CONOPS FOR THE UNITED STATES NATIONAL DATA CENTER
1.0 INTRODUCTION
1.1 Purpose
The CONOPS for the United States National Data Center (US NDC) describes how the Air
Force Technical Applications Center (AFTAC) employs this system, and describes operations, maintenance, and support responsibilities among various stakeholders.
1.2 Background
1.2.1 The US NDC is an operational geophysical data processing system for nuclear explosion monitoring. The US NDC continuously collects seismic, hydroacoustic, and infrasonic waveform data in near-real-time from sensors situated all over the world. These data are from a mixture of sources ranging from AFTAC-unique sensors, International Monitoring System
(IMS) data from the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO), and open-source data from the United States Geological Survey. The US NDC automatically processes acquired data to detect signals and it associates those detections to a common source to create an initial event hypothesis. The system presents the data and processing results to skilled analysts for further interactive processing and reporting using US NDC software tools.
1.2.2 Assistant Secretary of Defense for Atomic Energy (ASD/AE) assigned AFTAC the responsibility to develop and operate the US NDC effective 29 April 1994. These responsibilities were reaffirmed by the Chief of Staff of the Air Force on 2 May 1996. Further, the designation of AFTAC as the US NDC is reaffirmed annually by the Department of State and the U.S. Mission in Vienna via the Registration Form and Questionnaire for National Data
Centers and Authorized Users.
1.3 Relationship to Other CONOPS
This document directly supports the CONOPS for The United States Atomic Energy Detection
System (USAEDS) and describes the operational concept for US NDC in support of AFTAC’s treaty monitoring mission. Additionally, this CONOPS supports the CONOPS for the
Geophysical Field System.
2.0 REQUIREMENTS
• Comprehensive Nuclear Test Ban Treaty (CTBT), 24 September 1996 (U)
• Limited Test Ban Treaty (LTBT), 5 August 1963 (U)*
• Peaceful Nuclear Explosion Treaty (PNET), 28 May 1976 (U)
• Threshold Test Ban Treaty (TTBT), 3 July 1974 (U)
3.0 MISSION
Analyze and report on events using multi-technique data available from independent USAEDS sources, the International Data Center (IDC), bilateral sources, and other assets to detect, locate, identify, attribute, and characterize nuclear explosions.
4.0 COMMANDER'S ANALYSIS
4.1 The Assistant Secretary of Defense for Atomic Energy assigned AFTAC the responsibility to develop and operate the US NDC.
4.2 The US NDC provides the U.S. a unique capability to receive, process, archive, and report on worldwide near-surface and subsurface events of interest. It acquires, integrates, processes, analyzes, and archives data from seismic, infrasonic and hydroacoustic sensors, with inputs from
AFTAC-unique sites, IMS data from the CTBTO, and open-source data from the United States
Geological Survey. The US NDC provides the capability to create initial event assessments with a high-confidence level to AFTAC’s customers. The assessments are sent within one hour of identification for high priority events such as nuclear explosions and 24 hours for routine events such as earthquakes (which must be reviewed to discount a nuclear explosion). Reports from the US NDC are combined with reports from other USAEDS monitoring systems to produce integrated, multi-technique analysis products unique to AFTAC.
5.0 US NDC OVERVIEW
AFTAC
Figure 1: US NDC Overview
6.0 CHALLENGES
The US NDC and IDC software was designed 30 years ago and the system cmTently known as the US NDC became operational in 1995. The system cunently suppo1is approximately 1.2 million lines of executable software and the problems with this platfo1m are similar to other large, antiquated, legacy software systems. The system requires modernization for the following reasons:
6.1 AFT AC has patched and modified the software thousands of times leading to brittle software. Brittle software refers to changing a line of code and unintentionally breaking other functions, resulting in fmiher patching to fix those functions. This phenomenon of software entropy results in continuous change and increasing costs.
6.2 The methods and languages AFT AC programs the US NDC with is cmTently outdated and increases the technical difficulty and cost to maintain or add functionality to the system.
6.4 Information Assurance (IA) requirements have evolved dramatically since 1995; US NDC modernization must include compliance with applicable IA requirements.
7.0 ASSUMPTIONS
New data sources will be acquired from seismic, hydroacoustic, and infrasonic sensors to meet the requirements in section 2.0 of this CONOPS. These data will be acquired by the US NDC for analysis and reporting purposes. At all times, US NDC operations and maintenance personnel will maintain the persistent US NDC processing and storage capability sufficient to meet all anticipated data inputs known via a 5-year projection.
8.0 EMPLOYMENT CONCEPT
8.1 US NDC Data Flow
8.1.1 Sensor Interface to the US NDC
8.1.1.1 The USAEDS provides the means to verify signatory compliance with the LTBT, TTBT, PNET, and current nuclear explosion moratoria. The USAEDS is comprised of data sensors in the following techniques: seismic, materials (airborne and surface-based particulate debris and gas), infrasonic, hydroacoustic, and satellite including optical, infrared, and prompt radiation sensors (i.e., neutron and gamma ray). The US NDC is a critical component of the USAEDS.
The US NDC also collects and selectively processes data from other sources.
8.1.1.2 The US NDC acquires all IMS radionuclide and noble gas data available from the IDC.
The US NDC retains this data in order to meet data distribution requirements. The materials data processing system uses this data, although materials data processing is not performed on the US
NDC platform, it is performed on systems dedicated and optimized for the materials data collection mission.
8.1.2 International Data Center Interface
The US NDC receives all available IMS and IDC data products from the IDC and integrates it so that the US NDC contains a superset of IMS data, USAEDS data, bilaterally available data, and data from specified sources outside the USAEDS and IMS.
8.2 Sharing of International Data
The US NDC serves as the data distribution point for all U.S. Government and authorized users of IMS data. It is U.S. policy that U.S. IMS data should be openly available to the public. To fulfill this policy, U.S. IMS stations forward data to the United States Geological Survey and to the Integrated Research Institutes of Seismology, where they are publicly available. AFTAC provides IMS data from non-U.S. stations to any U.S. Government user for their official business, by request.
8.3 Training
The 312th Training Squadron Special Instruments Training Flight at Goodfellow Air Force Base, TX trains
8.4 Maintenance
The 709th Support Group (709 SPTG) performs hardware maintenance, system administration, and database administration on the operational system. The appropriate contracting office acquires US NDC software support (sustainment and maintenance) as a separate line item under the US NDC contract. As the US NDC is a geophysical data processing system, the Systems
Digital Division performs technical oversight of software modifications. The 709 SPTG hosts a
24/7 maintenance liaison/repair capability in the Maintenance Operations Control Center
(MOCC) to assure rapid system restoral and reduce outages to the minimum possible.
8.5 Program Management
The Treaty Monitoring Systems Division (SDA) will continue to execute the program to meet the requirements identified in the US NDC System Requirements Document as funding becomes available.
8.7 Remote Operating Center for the US NDC
The Remote Operating Center (ROC) provides login and analysis capability to the US NDC, or the ALT US NDC, from building 710 on PSFB. The ROC provides short-term mission coverage during scheduled and unscheduled outages. It is important to note that, unlike the ALT US
NDC, the ROC is not a replication of the US NDC. The ROC provides remote access to either the US NDC or the ALT US NDC, but the ROC does not have its own data acquisition, processing, or storage capability. Due to the limited number of workstations and slower interactive responsiveness, data analysis at the ROC will be prioritized as follows: 1) interactive review of events formed in the look-forward process, 2) interactive analysis of regional data, and
3) interactive analysis of global data.
8.8 US NDC Enhancements
The portion of the USAEDS mission performed by the US NDC is continuously improving capability. Enhancements to the USAEDS field systems must include performance and sustainment upgrades to existing sensor stations. The US NDC portion of the enhancement program consists primarily of software development to advance the state of automated detection, location, magnitude/yield, and classification functionality. In addition, as the number of events increase, AFTAC requires advance software development to increase the efficiency of the interactive data analysis.
8.9 Phased Development of US NDC
AFTAC developed the US NDC in a phased approach, allowing for planned upgrades and enhancements during the development lifecycle. During each phase, functionality has been delivered, with each incremental build providing new capabilities and easing the transition into the new software. However, the current US NDC software platform is beyond any reasonable expectation of its lifecycle. In order to address the challenges outlined in Section 6, AFTAC redirected its limited US NDC Research and Development (R&D) funding away from additional expansion of the current platform towards the definition of a modernized US NDC architecture.
AFTAC established the US NDC Modernization program to address system obsolescence.
