Budget Battle: GPS Program Funding Appears Solid

The GPS program appears well positioned to weather another round of budget cuts, although some contractors that support the program may not be so fortunate.

“I would expect GPS will be relatively protected (with) continued investment and modernization of the satellite constellation.” said Robert Levinson, a senior defense analyst for Bloomberg Government during an October 28 briefing.

“GPS is in fairly good shape,” confirmed an expert familiar with the Air Force’s budget.

Bring Real-World GNSS Satellite Signals Back to the Lab . . . with More Detail Than Ever

Spirent GSS6425 Record and Playback System

Spirent Communications has unveiled a new system for recording real-world GNSS RF signals and replaying them in the lab.

“Record and Replay” is popular as a more rigorous — and, crucially, repeatable — approach to GPS and GNSS testing than using live signals in real time, where satellite positions and atmospheric conditions are constantly changing.

GAO Report: More Research Needed to Determine GPS Program Changes

Air Force officials should get more cost and user information and determine how many GPS satellites they will support before making decisions about revamping the navigation system, the Government Accountability Office (GAO) has told Congress.

Although an Air Force report about program options was “a good starting point, more information on key cost drivers and cost estimates, and broader input from stakeholders would help guide future investment decisions,” the GAO wrote in an assessment of the defense agency’s analysis.

Building a BeiDou Simulator

BeiDou-2 Is Born
The year before the main release, China surprised the global community when it published just a test version of the promised ICD for the BeiDou-2 B1 open signal. In this document, the modulation scheme for the signal was confirmed and the pseudorandom code generator for the ranging signal was described.

Last month, USAF Col. Bernard Gruber stepped down after three years of running the Global Positioning Systems Directorate at Los Angeles Air Force Base.

The GPS Directorate, originally established in 1974 as the NAVSTAR GPS Joint Program Office, is responsible for development, acquisition, fielding and sustainment of all GPS space segments: the modernized operational control segment (OCX), the next-generation GPS III satellites, and modernized GPS user equipment (MGUE).

Lockheed Martin has delivered a full-sized, functional prototype of the next generation GPS satellite to Cape Canaveral Air Force Station.

The GPS III Non-Flight Satellite Testbed (GNST) arrived at the Cape on July 19 where it will be used to test facilities and pre-launch processes in advance of the arrival of the first GPS III flight satellites, which will undergo similar testing. The first flight GPS III satellite is expected to arrive at Cape Canaveral in 2014, ready for launch by the U.S. Air Force in 2015.

FAA and Defense Department Work to Fix Civil GPS Funding

Federal officials are working to fill a funding shortfall nearly certain to occur next year given that both the House and Senate have cut an already halved budget request for GPS civil funding.

Sources confirm the Federal Aviation Administration (FAA) and the Department of Defense (DoD) are in talks about finding money to make up for the dramatic reduction. One source familiar with the situation said the FAA was searching its accounts for resources to address the loss.

Congress Slashes Civil GPS Funding

Congress Slashes Civil GPS Funding

In a set of decisions that could potentially slow GPS modernization both the House and Senate Appropriations Committees this week slashed funding for the civil community’s contribution to the GPS system from the Fiscal Year 2014 (FY14) budget.

The House eliminated the entire amount of the White House budget request for $20 million, which is paid through the Federal Aviation Administration (FAA). The Senate cut a mere $5 million — 25 percent of what had been the requested.

House Committee Makes Deeper Cuts to FY14 GPS Budget

House Committee Makes Deeper Cuts to FY14 GPS Budget

The House Appropriations Committee has made a series of cuts to GPS programs that, if agreed to by the Senate, suggest an overall slowdown in the pace of GPS modernization.

While lawmakers on the House Authorization Committee agreed to the full amount of each of the president’s GPS-related requests, their counterparts on the Appropriations Committee cut a total of just over 9 percent from the total budget request for GPS spacecraft, ground systems, and user equipment.
