UNNO Statement of Objectives Summary
This is a Statement of Objectives (SOO) document for the Unified Network and Navigation Operations (UNNO) contract issued by NASA's Marshall Space Flight Center. The UNNO contract consolidates operations, maintenance, sustainment, and integration of NASA's Near Space Network (NSN) and applicable portions of the Deep Space Network (DSN) under a single contract vehicle. The resulting PWS and SOW will serve as the basis for a Task Order under the UNNO IDIQ contract. Offerors may propose either Firm-Fixed-Price (FFP) or Cost-Plus-Award-Fee (CPAF) contract types, with a minimum of 10% of work proposed on an FFP basis. Offerors must submit an Objective Fulfillment Narrative (OFN) explaining how proposed solutions satisfy the objectives with direct cross-references to applicable PWS or SOW sections, and modification of the attached Functional Construct Set is permissible if clearly explained and aligned within the OFN.
The SOO identifies six primary government objectives: (1) Mission Continuity with uninterrupted network operations achieving specific service availability thresholds (NSN Nominal ≥97%, NSN Critical ≥99%, DSN Nominal 95%, DSN Mission Critical 98%); (2) Efficiency in contract execution through unified management, configuration commonality, standardized mission interfaces, automation, sustainment discipline, supply chain integration, and continuous improvement; (3) Safety culture and compliance with integrated Safety, Health, and Environmental programs, hazard control, qualified personnel, rigorous reporting and investigation, extended enterprise safety, and mission assurance integration; (4) Transition of developed CapDev capabilities into operations with early operations participation, disciplined transition processes, cross-regime integration, and Enterprise Service Management framework; (5) Augmentation of NSN capacity through commercial services with integrated demand/capacity management, effective use of commercial aperture portfolio, provider and mission interface establishment, and service continuity across boundaries; and (6) Unified cybersecurity standards with a single cybersecurity program covering IT and OT systems, compliance with current Federal and NASA standards (NPD 2810.1, NPR 2810.1, NIST SP 800-171 Rev. 3, NIST SP 800-172, CMMC 2.0, and related standards), authorization and continuous monitoring, interconnection governance, incident response, space asset protection, unified security metrics, and third-party cyber assurance. Key scope includes all CONUS-based DSN facilities, NSN services (TDRS and DTE), unified network management, flight dynamics services, and Mission Integration and Special Studies support across multiple principal facilities and sites.

1.0 PURPOSE
This Statement of Objectives (SOO) describes the Government's desired outcomes for the Unified Network and Navigation Operations (UNNO) contract. Following the solicitation instructions of Section L, offerors are to use the Government objectives described in Section 4 below along with the attached Functional Construct Set (FCS) to propose a PWS, SOW and Performance Requirements Summary mapped to measurable performance standards. Each objective in Section 4 is followed by the Government's expected outcomes. These outcomes represent a non-exhaustive list of desired end results, and offerors may propose outcomes not explicitly detailed herein.
Offerors may propose either a Firm-Fixed-Price (FFP) or a Cost-Plus-Award-Fee (CPAF) contract type to accomplish the stated objectives based on contractor risk profile. Objectives proposed on an FFP basis shall be incorporated into the PWS and mapped to measurable performance standards within the PRS. Objectives proposed on a CPAF basis shall be incorporated into the SOW. Offerors must propose at least 10% of the work as FFP.
Offerors’ proposal must include an Objective Fulfillment Narrative (OFN) explaining how the proposed solutions satisfy the objectives, including direct cross-references to the applicable PWS or SOW sections. Modification of the FCS, including significant structural changes, is permissible, provided that the transformation is explained, and the alignment of objectives is clearly demonstrated within the OFN.
The resulting PWS and SOW will be used as the basis for a Task Order under the UNNO IDIQ contract. Nothing contained in the below Section 3 Scope limits the overall scope of the UNNO IDIQ as described in the UNNO Scope of Work document.
2.0 BACKGROUND
NASA's Space Communications and Navigation (SCaN) Program, within the Research and Technology Mission Directorate (RTMD), serves as the Program Office for all NASA space communications and navigation activities. SCaN provides services anywhere in the solar system across the full mission life cycle, from launch through end of life and/or deorbit.
These capabilities are currently delivered through two separately managed projects:
Table 2.0-1 Current Networks
Network Managing Center Domain Principal Services
Deep Space Network (DSN)
Jet Propulsion Laboratory (JPL)
Beyond ~2 million km
Deep space TT&C, Radiometrics, Radio Science, VLBI
Network Managing Center Domain Principal Services
Near Space Network (NSN)
Goddard Space Flight Center
(GSFC)
Up to ~2 million km from Earth
Space Relay (TDRS), Direct-to-Earth (DTE) services
Both networks operate continuously, 24 hours a day, 7 days a week, providing telemetry, tracking, and commanding (TT&C), high-rate data downlink, and radiometric tracking services. SCaN is evolving its management and operational structure to form an integrated network operations team advancing a single "One Network" operational construct.
SCaN's capabilities will continue to evolve through increasing use of commercial services across the Earth, lunar, Mars, and deep space domains; however, not all capabilities will be fully commercialized. Certain mission-critical functions will continue to rely on Government-owned systems where necessary to ensure performance, resilience, and global coverage. UNNO is intended to consolidate operations, maintenance, sustainment, and integration of the NSN and applicable portions of the DSN under a single contract vehicle to improve efficiency, interoperability, resiliency, and cost-effectiveness.
3.0 SCOPE
The following networks and functions are anticipated to be within scope:
• Unified Network Management — enabling the "One Network" operational construct including Flight Dynamics Services, integration of operational Capability Development (CapDev) projects and planning for use of increased commercial services.
• Deep Space Network — all CONUS-based facilities (Goldstone DSCC, JPL Mission Operations Center, and current functions from DSN Operations and Maintenance (O&M) Facility), plus global logistics and selected activities needed to coordinate with the worldwide DSN footprint (MDSCC and CDSCC operations and maintenance are obtained through international agreement).
• Near Space Network — Space Relay (TDRS) and Direct-to-Earth (DTE) services
• Mission Integration and Special Studies (MI&SS) support
Principal facilities and sites are identified in the reference documentation and include, but are not limited to:
• White Sands Complex (WSGT, STGT, ETGT, TOCC)
• Blossom Point Remote Station
• Guam Remote Station
• Australian TDRS Facility
• Blue Mesa
• BRTS sites
• NSOCC, MMA, BATCAVE, SNAS Test Bed
• Alaska Satellite Facility
• McMurdo Ground Station
• Wallops Ground Station
• Bermuda Tracking Station
• Launch Communications Segment (Ponce de Leon, Kennedy Uplink Station/MIL- 71)
• Goldstone DSCC (SPC-10, Emergency Control Center)
• Space Flight Operations Center/DSOC
• DSN O&M Facility (DTF-21, CTT-22, ROC, DSN Logistics Facility)
• Flight Dynamics Facility (FDF)
4.0 GOVERNMENT OBJECTIVES
4.1 UNNO-SOO-1
Objective 1 — Mission Continuity: Uninterrupted Network Operations
Desired Outcome: No mission customer experiences a degradation of service as a consequence of contract transition, network unification, organizational change, or the introduction of new systems and providers. Service delivery is continuous, proficient, and resilient.
Expected Result:
1.1 Zero-Impact Transition. 24x7 operational continuity across all sites throughout contract transition, including retention of critical skills, uninterrupted certification currency for operations and maintenance personnel, seamless assumption of Government property accountability, and continuity of mission customer interfaces.
Transition risk should be actively managed and reported, with clearly defined off-ramps and contingency plans.
1.2 Sustained Service Performance. Achievement of, or improvement upon, established service performance levels:
Table 4.1-1 Operational Performance
Network Measure Threshold Basis
Near Space Network (NSN)
Service Availability — Nominal ≥ 97% Averaged over one month
Service Availability — Critical ≥ 99% Averaged over one month
Network Measure Threshold Basis
Operational Service Proficiency (SR Only)
≥ 99.90% Averaged over one month (Standard of Excellence ≥ 99.97%)
Operational Service Proficiency (DTE Only)
≥ 99.0% Averaged over one month
Deep Space Network (DSN)
Service Availability — Nominal 95% Per Applicable Agreements
Service Availability — Mission Critical Event
98% Per Applicable Agreements
Note:
Proficiency – Proficiency is the percentage of time services that were provided out of the total service time scheduled in a period.
Proficiency = (Tsch – Tloss) / Tsch, where Tsch is the total of all service time scheduled in the period, and Tloss is defined as the total of service times lost in the period.
Availability – Availability is the percentage of time services that are available for customer support.
Availability = (Texp – Tdown) / Texp, where Texp is defined as the time the service is expected to be available (24x7), and Tdown is defined as the total amount of time the service is not available.
Performance must satisfy or exceed customer requirements documented in mission requirements and interface documentation.
1.3 Follow-the-Sun Continuity. Reliable execution of Follow-the-Sun Operations (FtSO) across the DSN complexes, including disciplined transfer of network control between complexes and timely, direct technical support to CDSCC and MDSCC.
1.4 Continuity of Operations and Disaster Recovery. Management of network systems and facilities for continuity of operations in accordance with NPD 1040.4C and NPR 1040.1A, including maintenance and exercise of Continuity of Operations Plans and Emergency Preparedness and Disaster Recovery Plans, and maintenance of the Goldstone Emergency Control Center (ECC) in a state of operational readiness with regular activation exercises.
1.5 Critical Event Assurance. Readiness for launch and early orbit, critical maneuvers, planetary encounters, Artemis operations, reentry, and spacecraft emergencies, including immediate response to discrepancies during critical support periods.
1.6 Space Asset Longevity. Safe and secure operation of the TDRS constellation to maximize useful on-orbit life, including conjunction assessment and avoidance, anomaly response, trending, and end-of-mission planning.
1.7 Facility Operations. Maintain hardware and software assets to ensure continuous network operations, resiliency, and targeted improvements. Identify prioritized sustainment tasks with network uptime return on investment.
4.2 UNNO-SOO-2
Objective 2 — Efficiency in Contract Execution and Network Operations
Desired Outcome: UNNO to deliver credible, auditable baseline and method for quantifying efficiencies for example: (cost per service hour, cost per supported event, labor hours per deliverable, mission onboarding cycle time, mean time to repair, discrepancy closure rate, and similar measures).
Expected Result:
2.1 Unification Efficiencies. Elimination of duplication created by parallel NSN and DSN management structures — consolidated management systems, common tools and processes, consolidated training and certification programs, unified reporting, and a single set of integrated plans in place of parallel network-specific plans.
2.2 Configuration Commonality. Configuration of underlying layers of hardware, operating systems, applications, scripts, settings, and tailoring made similar across SCaN One Network systems to facilitate reuse and eliminate duplication.
2.3 Standardized Mission Interfaces and Onboarding. A standardized interface experience for missions, with standardized interfaces, protocols, and data exchange across the integrated networks to the maximum extent practicable, reducing per-mission integration cost and cycle time. A simplified concept-of-operation and onboarding construct that reduces per-mission customer interfaces and reduces cost over time to cover the mission set.
2.4 Automation and Digital Transformation. Automated collection and reporting of contractor progress, network health, Discrepancy Reports, status, and network metrics
— reducing manual reporting labor while increasing Government insight. Automation of routine operational configuration, monitoring, scheduling, and product generation where it demonstrably reduces cost or risk without reducing reliability.
2.5 Sustainment and Obsolescence Discipline. A single integrated Sustainment Plan with an annual assessment capturing the basis of estimate for Non-Recurring Engineering (NRE), design, implementation, testing, and fielding of each candidate item, described in sufficient detail that labor, cost, and schedule impacts can be estimated without significant rediscovery effort. Sustainment items shall be ranked in priority order and supported by risk and life-cycle cost-benefit rationale to inform the Government's annual five-year budget formulation.
2.6 Supply Chain and Logistics Efficiency. Integrated Supply Chain Management (ISCM) capability spanning both networks, including reliability/maintainability analysis, early obsolescence identification and escalation, common sparing philosophy, and consolidated global logistics coordination.
2.7 Continuous Improvement as a Standing Obligation. Established, documented, and implemented processes to improve performance, reduce cost, and increase customer satisfaction, with improvement opportunities and realized savings reported at recurring management reviews. The Government expects the contractor to bring forward ideas for improvement proactively rather than solely in response to direction.
4.3 UNNO-SOO-3
Objective 3 — Safety Culture and Compliance with Safety Standards
Desired Outcome: No serious injuries, no preventable mishaps, and a workforce at every site that visibly owns safety as a personal and organizational value.
Expected Result:
3.1 A Genuine Safety-First Culture. A workplace culture in which personnel are empowered to identify unsafe conditions and exercise stop-work authority when conditions present imminent danger to personnel, property, or operations — with work placed in a safe condition, appropriate notification made, and resumption only upon authorization by the appropriate authority. Hazard reporting, employee involvement, mutual accountability, and procedural compliance shall be encouraged without fear of reprisal.
3.2 Integrated Safety, Health, and Environmental (SHE) Program. A comprehensive SHE program integrating environmental compliance, occupational safety, and worker health protection across all locations where contract work is performed — Government-controlled and contractor-controlled alike — in accordance with applicable international, Federal, state, and local requirements; environmental Executive Orders; NASA Procedural Requirements; and Center directives.
3.3 Hazard Control Commensurate with Risk. Identification and control of hazards associated with maintenance, testing, construction-like activities, facility modifications, transportation, material handling, machine operations, hazardous energy (lockout/tagout), electrical systems, elevated work (including antenna structures and aerial work platforms), confined spaces, pressure and cryogenic systems, hazardous materials, high-power RF radiation, laser operations, fire hazards, and environmental conditions.
3.4 Qualified and Current Personnel. Personnel that are trained, qualified, certified, medically cleared, and otherwise authorized before performing hazardous, specialized, or regulated work.
3.5 Rigorous Reporting and Investigation. Routine workplace inspections; prompt reporting, documentation, and investigation of incidents, injuries, illnesses, close calls, and unsafe conditions; preservation of evidence; determination of root causes and contributing factors; and corrective actions tracked to closure, consistent with NPR
8621.1 and Center anomaly notification requirements.
3.6 Extended Enterprise Safety. Flow-down of applicable safety requirements to subcontractors, vendors, temporary personnel, and visitors, with hazard communication, control verification, and oversight commensurate with activity risk.
3.7 Mission Assurance Integration. An integrated Mission Assurance Program applying disciplined processes for risk management, quality assurance, reliability, readiness, anomaly resolution, corrective action, and continuous improvement — with mission assurance considerations incorporated into hazard analyses, work planning, change implementation, and operational decision-making.
4.4 UNNO-SOO-4
Objective 4 — Transition of Developed Capabilities into Operations
Desired Outcome: Every capability delivered by the SCaN CapDev portfolio enters UNNO-managed operations on its committed date, fully verified, documented, staffed, sustainable, and integrated into the One Network service model — without creating a parallel operating model, an orphaned system, or technical debt inherited by the Government or by successor contracts.
Expected Result:
4.1 Early and Continuous Operations Participation in Capability Development (CapDev).
Operations engagement across the CapDev workflow — from unmet-need capture and requirements/CONOPS refinement through the CapDev Control Board decision points, formulation memorandum, implementation strategy and capability roadmap, and ultimately the Operational Readiness Review decision — such that operability, sustainability, staffing, and lifecycle cost considerations are reflected in the delivered design rather than discovered at handover. The Government's expectation, consistent with CapDev tenets, is that no capability is received into operations without a demonstrated user commitment and a defined operational home.
4.2 Disciplined Transition-to-Operations. A repeatable, documented transition process covering entry and exit criteria, ORR support, verification and validation, interface control documentation, operations and maintenance procedure development, operator and maintainer training and certification, spares and sustainment baseline, security authorization, and formal operational acceptance. Transition schedules shall be integrated with mission need dates and with the network's existing operational commitments.
4.3 Integration Across All Three Regimes. Capabilities delivered for Earth, cislunar, and Mars/deep space regimes shall be integrated into a single service model, so that a mission experiences one service interface irrespective of regime, network, or provider, including missions whose trajectory crosses regime boundaries.
4.4 Enterprise Service Management as the Integration Spine. New capabilities shall be integrated through the common Enterprise Service Management framework — common scheduling, monitoring, data management, service accounting, and reporting spanning Government and commercial providers — rather than through capability-unique interfaces.
4.5 UNNO-SOO-5
Objective 5 — Augmentation of Near Space Network Capacity Through Commercial Services
Desired Outcome: Integration of commercial services used as a routine, primary means of meeting Government near-space demand during oversubscription;
Government-owned near-space capacity is thereby optimized for priority demand.
Expected Result:
5.1 Demand and Capacity Management Across Government and Commercial Assets.
An integrated, forecast model to identify the balance of commercial services to augment the mission portfolio demand matched against available Government-owned and commercially contracted capacity.
5.2 Effective Use of the Commercial Aperture Portfolio. Augmentation of UNNO capacity through use of the commercial antenna portfolio available under commercial services, with no organizational conflict of interest, across the Earth-proximity, GEO-to-cislunar, and beyond-cislunar subcategories.
5.3 Establishment of Provider and Mission Interfaces. Establishment and sustainment of the interfaces required for commercial providers and missions to operate through the Government's scheduling and cloud interfaces.
5.4 Continuity Across Service Region Boundaries. An operational and scheduling approach for missions whose trajectory or transfer crosses the near-space subcategory boundaries, and for missions that transition between commercial and Government providers or between near-space and deep-space support, with no loss of service, no unplanned mission cost, and no dependence on a single provider.
4.6 UNNO-SOO-6
Objective 6 — Unified Cybersecurity Standards and Modern Cyber Compliance
Desired Outcome: A single, coherent, modern cybersecurity posture spanning the unified network, eliminating the divergent, network-specific security regimes inherited from separate NSN and DSN arrangements, that protects mission-critical space and ground systems against evolving threats while maintaining Authorizations to Operate.
Expected Result:
6.1 One Unified Cybersecurity Program. A single Cybersecurity Program covering all systems, networks, applications, devices, services, and data used in contract performance — spanning both information technology (IT) and operational technology (OT), including mission-critical control systems, antenna control, SCADA, and spacecraft command paths. Where NSN and DSN currently apply differing standards, tools, or processes, the Government seeks convergence to a single, defensible baseline.
6.2 Compliance with Current Federal and NASA Standards. Compliance with applicable cybersecurity laws, regulations, standards, and directives, including but not limited to:
Table 4.6-1 Compliance Standards

Offerors must propose to the current revision of applicable standards; where the reference documentation cites superseded revisions, the current revision governs.
6.3 Authorization and Continuous Monitoring. Obtaining and retaining Authorizations to Operate (ATO); maintaining IT System Security Plans in NASA's system of record;
developing, implementing, and maintaining Plans of Action and Milestones (POA&M);
and supporting NASA-mandated security audits, the annual Security Assessment and Authorization exercise, and annual penetration testing.
6.4 Interconnection Governance. Management of Interconnection Security Agreements (ISAs) covering service interfaces with external entities not overseen by a SCaN Authorizing Official, including commercial service providers, international partners, and mission operations centers.
6.5 Incident Response. Prompt identification, reporting, containment, investigation, and recovery from actual or suspected cybersecurity incidents, unauthorized access, malicious code events, data spills, and losses of confidentiality, integrity, or availability
— with evidence preservation, root cause analysis, and corrective actions tracked to closure.
6.6 Space Asset Protection. Maintenance and exercise of protection strategies for the TDRS space segment and support to NASA end-to-end threat assessments.
6.7 Unified Security Metrics. Monthly reporting of security status and metrics reflecting boundary control, configuration management, contingency planning, incident response, system monitoring, user access control, and vulnerability mitigation — reported on a common basis across both networks rather than in incompatible network-specific formats.
6.8 Supply Chain and Third-Party Cyber Assurance. Flow-down of cybersecurity requirements to subcontractors, suppliers, cloud providers, and external service providers, with contractor responsibility for their compliance and integration into the overall program.
5.0 CONSTRAINTS AND ASSUMPTIONS
1. 24x7 operations are non-negotiable: Both networks operate continuously; no proposed efficiency, transition step, or contract-type conversion may compromise continuous service.
2. International complexes are outside operations scope: MDSCC and CDSCC operations and maintenance are obtained through international agreement; UNNO scope is limited to global logistics coordination and selected coordination activities for those complexes.
3. The Government-owned footprint may decrease: Commercial capability growth may reduce Government-owned assets over the contract life; proposed approaches should be scalable in both directions.
4. Data deliverables are governed by the CDRL/DRL: Contract documentation shall be produced, controlled, and maintained in accordance with the Data Requirements Descriptions and Data Requirements List.
5. Government-furnished property will be provided: Certain facilities, office space, administrative computing/LAN services, IT systems, and heavy equipment will be Government-furnished at defined locations; the contractor is expected to provide the remainder.
