PE2 - GNSS Content & Workflow

1. End State Visual Graphic

(U) At a high level, the mission workflow for PNT data is:

(U) The “system of models” in the center is a variety of NGA and mission partner systems. GNSS contributes to this workflow at the point noted on the upper left side – it is one of the “coordinate sources”, namely being the provider of AFSPACECOM GPS high accuracy

PNT and satellite ephemeris information. Multiple critical GEOINT mission workflows rely on this data source.

(U) The system architecture view is available on COE.

Epic Owner: Trevor

Garner

Epic Description: Value Proposition (what you’re building) (U) The NGA Precise

Navigation and Timing (PNT) mission area provided high accuracy navigational ephemeris data to NGA and external customers for a variety of missions. PNT data is essential for creating geographically precise GEOINT products, geolocating artifacts within GEOINT products, and for a number of NGA military support missions. Furthermore, the NGA network augments the core AFSPACECOM-owned GNSS (GPS) ground control network by providing additional sources of information from the on-orbit assets.

For NSG Analysts and DoD mission partners

Who require PNT data and products

Our implementation

Is a automated and streamlined content processing flow, and incorporation of new data sources

That provides highly reliable PNT data

Unlike the current solution

Our Solution provides dramatically increased distributed locations

Business Outcome Hypothesis: (U) Obtaining PNT content from a robust selection of sources so that customers are able to obtain high precision navigation and timing data to meet production needs.

Users and Markets Affected: Beneficiaries (U) All GNSS customers

Impact on Products, Programs and Services/ Buy-In

• (U) Requires continued SME support from NGA/SF for software development and data processing insight.

• (U) Requires AFSPACECOM as the mission partner and space constellation operator to provide an operational GPS constellation

• (U) Leverages international navigation satellite systems for augmenting data where appropriate.

• (U) Leverages worldwide navigation satellite expertise and science development to augment

NGA’s contributions for US systems.

Impact on Sales, Distribution, Deployment/ Deployment

(U) GNSS is a key contributor to the overall national navigation satellite capability operated by

AFSPACECOM. The AFSPACECOM mission partner has significant dependencies on NGA delivering its part of the overall enterprise solution. Additionally, multiple product productions rely on precise navigation and timing to generate highly precise GEOINT.

Type of Return:

(U) Continued availability of high accuracy PNT content to enable the production of GEOINT, and continued operation of the national GPS navigation system.

Anticipated Business impact Mission

Achievement:

(U) Deliver mission capability for all PNT consumers, both NGA and external.

In-house or Outsourced Development: (Adapt, Adopt, Buy, Build)

(U) Combination of in-house and outsourced. The AFSPACECOM GPS program is the key external source in that GPS mission data and science originate from there. Additionally, international PNT efforts – both government systems and academia – are leveraged to augment the body of knowledge and to advance the science. NGA/SF is the internal NGA provider of

PNT science SME.

Incremental Implementation Strategy:

(U) See program plan

Sequencing and Dependencies + Key Partners:

(U) GNSS is primarily driven by the AFSPACECOM GPS program. The NGA’s GNSS technical baseline must always conform to and integrate with the overall GPS constellation enterprise solution. This does at times limit what NGA can do with respect to changes / modifications, and also drives requirements to NGA that come from satellite block updates to

GPS as new satellites are built and launched.

(U) Gap Statement

(U) Statement Title

(U) Autonomously and continuously monitor the GPS Satellite System / WGS-84 Reference

Frame Collection Sites

(U) Description: WGS-84 Reference Frame Collection Sites

(U) The WGS-84 Reference Frame Collection Sites capability expands the current level of reference framing from our current GNSS limited set of sites of 16 NGA referenced sites and 30

ITRF GNSS Stations. There are approximately 1,500 GNSS sites, 50-80 Satellite Laser Ranging

(SLR) sites, 32 Very Long Baseline Interferometry (VLBI) sites, and an unknown number of

French Doppler Satellite DORIS capable sites. Below in Table 1: Satellite Geodesy techniques

Impact on Reference Frame Calculations, is shown the capabilities for each type of geodetic technique and the impacts to the Reference Frame Calculations.

(U) A reference frame is made up of 4 components, an origin, an axis, a scale and reference points.

1. Origin – simply the point in space from which everything is measured. ZERO

2. Axis - for each spatial dimension, a line for each direction, usually 3 lines, x, y and z.

3. Scale – units of length or distances within the reference frame

4. Reference Points – real world points that uniquely fix the coordinate system

1. NGA uses 16 GNSS Monitoring Stations

Figure 1 Reference Frame

(U) Expanding the GNSS base and incorporating the SLR and VLBI satellite data will enable

NGA and DoD to become independent of the ITRF reference frame services, by being able to produce our own scale and origin calculations for the WGS-84 Reference Frame service.

ITRF, inclusive of the French DORIS data set.

Figure 2: Comparison of the ITRF and WGS Reference Frame Data Sets

(U) Rationale for the Gap

(U) Current Rationale

(U) NGA is required to independently produce a reference frame capable of supporting the DoD.

Our current process relies heavily on the ITRF reference frame for its basic underpinnings.

(U) Recommend Rationale

(U) The WGS 84 Reference Frame (RF) is the official DoD terrestrial reference frame. All DoD maps and charts should be in the WGS 84 frame, and all DoD positioning and navigation are required to be in the WGS 84 frame. As such, the Global Positioning System (GPS) operates in the WGS 84 frame as do all GPS users.

(U) Current US policy is to keep the WGS 84 frame in alignment with the International

Terrestrial Reference Frame (ITRF), the international scientific reference frame. To meet this requirement, NGA aligns the WGS 84 RF to the ITRF rather than creating the RF from raw data.

(U) Without these expanded WGS-84 Reference Frame Collection Sites, DoD navigation, and charts, are fundamentally dependent upon an international scientific product.

(U) Who the Gap Benefits

(U) The ability of the agency to provide an independent WGS-84 Reference Frame to the DoD, commands, and the NSG.

(U) Rationale for Measures

(U) Original Statement

(U) NGA is required to independently produce a reference frame capable of support the DOD.

Our current process relies heavily on the ITRF Reference frame for its basic underpinnings.

(U) Recommended Statement

(U) NGA is required to independently produce a reference frame capable of supporting the

DOD, which means that NGA must be able to collect and process the components for a reference frame: the origin, the axis, the scale and the reference points. To accomplish this NGA needs to increase the number of collection sites and the type of collection sites, to include the additional

GNSS sites, SLR and VLBI sites. The addition of the SLR and VLBI sites will enable the reference frame for scale, and origin, which were vacant in NGAs current collection processes. A minimal set of these sites established the threshold level for the measures. The objective measure is to increase the resiliency and resolution of the quality of the product.

(U) Measures

(U) Current Measures

(U) Threshold: Autonomously and continuously monitor all GNSS data sources

(U) Objective: Autonomously and continuously monitor all WGS-84 data sources (GNSS, SLR, VLBI and Doppler-DORIS)

(U) Recommended Measures

1. (U) Autonomously and continuously monitor at least 50 GNSS data sources

2. (U) Autonomously and continuously monitor on each tectonic plate globally
