About this file
This document is a Questions and Answers (Q&A) file for a Draft Statement of Work (SOW) for Space Weather Observations Antenna Network Commercial Services. The document covers ten key questions from potential contractors regarding NOAA's planned commercial antenna services, with specific focus on two observatory missions: SWFO-L1 and SOL-A. Key details include NOAA's intent to procure commercial antenna services for global X-band downlink coverage and Southern hemisphere S-band ranging, with the base contract period spanning April 2026 through March 2027. NOAA has not yet decided whether to award single or multiple contracts and allows contractors to propose team agreements and subcontractors.
Notable technical requirements include operational availability for each observatory separately, integration of Commercial Antenna as a Service (CAaaS) with the Space Weather Observations Antenna Network (SAN) system, and a preference for locally-hosted solutions at ground sites to meet cybersecurity and data storage requirements. The contract aims to provide continuity to existing global X-band coverage for SWFO-L1 and prepare for future integration of the SOL-A mission, with contractors expected to conduct their own analysis to fulfill system requirements such as operational availability, global visibility, and service gap considerations.

DRAFT SOW: Space Weather Observations Antenna Network Commercial Services
Notice ID: DraftSOW-SWO-SAN-CommercialSVCS-2025
Questions to the SOW:
1. Regarding 3.2.1 Baseline Service: Are the existing SWFO OCONUS antennas sufficient to support service for one observatory at a time?
Answer: The availability and G/T requirements for ground antennas supporting SOL and SWFO-L1 are the same, so if the existing OCONUS antennas meet the needs for SWFO-L1 then they will be sufficient to support one observatory at a time. The expectation is that contractors will conduct their own analysis to determine the ground station assets needed in order to fulfill the relevant system requirements such as Operational Availability, Global Visibility, and the Service Gap.
2. Regarding 3.2.2 Option 1: Does operational availability apply to each SWO Observatory separately, or to both as a unit? Are the spacecraft redundant?
Answer: Operational availability applies to each SWO Observatory separately. The spacecraft are not redundant.
3. Regarding 3.4 and the anticipation that the SAN interfaces will be modified, please elaborate on what interface development is expected of the contractors, is there any additional information about these functional interface modifications?
Answer: The current SAN interface was developed to support the SWFO-L1 mission. Interface development will be required to expand the SAN to interface with additional NOAA-owned ground station assets and enable support of the SOL-A mission in addition to SWFO-L1, but no significant changes to the commercial antenna as a service interface are expected. This contract has not been awarded yet so no additional information is available at this time.
4. Does NOAA intend to award multiple CAaaS contracts for X-Band Global Coverage or a single contract to a single provider?
Answer: No decision has been made about the one versus multiple contracts for global X-band coverage. Contractors are allowed to propose team agreements and identify subcontractors needed to meet performance requirements.
5. Does NOAA intend to award multiple CAaaS contracts for Southern Hemisphere S-Band Ranging or a single contract to a single provider?
Answer: No decision has been made about the one versus multiple contracts for Southern hemisphere S-band Ranging. Contractors are allowed to propose team agreements and identify subcontractors needed to meet performance requirements.
6. Does NOAA intend to award different contracts for X-Band Global Coverage & Southern Hemisphere S- Band Ranging?
Answer: The global X-band downlink coverage and Southern hemisphere S-band ranging could be different contracts or different options on one contract.
7. Are the dates listed as April 2026 through March 2027 accurate such that NOAA is only looking for existing providers of existing capacity in S/X and Southern Hemisphere Ranging?
Answer: The base year of April 2026 through March 2027 is accurate. During this year and until the launch of SOL-A, NOAA is looking to provide continuity to the existing global X-band coverage for SWFO- L1, but that does not necessarily imply using the same provider(s).
8. How long does NOAA expect the integration of CAaaS with the SAN system to take?
Answer: The integration of CAaaS with the SAN system could be a multi-step process, with a comparatively quick turnaround for service to SWFO-L1 using the existing SAN system and a longer process to eventually integrate SOL-A into the expanded SAN system. Please provide your estimated timeline(s) to onboard SWFO-L1 and SOL-A.
9. Does NOAA intend to procure additional services in the event of Launch, Anomaly, or Space Weather Events over the existing baseline requirements?
Answer: NOAA does not intend to procure additional commercial antenna services to support Launch, Analogy, or Space Weather Events.
10. Does NOAA prefer a Public cloud-hosted solution to meet NIST cybersecurity requirements?
Answer: NOAA prefers a locally-hosted solution at each ground site to meet storage requirements to guard against the possibility of lost data in the event that the ground site becomes isolated from the network.
