Cut to GPS OCX Civil Funding Could Trigger New Delays as Scrutiny, Pressure Mount

With final passage of the Omnibus spending bill on December 13 Congress deepened by $17 million the fiscal ditch in which the new GPS ground system finds itself, possibly further delaying the completion of a modernized operational control segment (OCX) and increasing costs just as the Department of Defense’s top acquisition official steps in to take a closer look at budget overruns.

The launch of the first GPS III satellite could slip to as late as March 2017, further delaying a modernization program that already has been pushed back repeatedly by budget cuts and technical problems.

“The first GPS III launch is tentatively considered for the first half of FY17, based on booster availability and Air Force launch priorities,” a spokesman for the Space and Missile Systems Center told Inside GNSS.

OCX Program Restructured, Delayed Again

Editor’s Note: An exclusive interview with Gen. Hyten is available here with more details.

Details are emerging about another restructuring of the contract for the new GPS ground system, a deal that pushes completion of the project back another two years and recasts the remaining work to fit within the Air Force’s strained financial profile.

IFEN Launches SX3 Software Receiver

IFEN SX3

IFEN introduced its new SX3 GNSS software receiver, a major upgrade of the company’s SX-NSR, last week at the ION GNSS+ conference in Tampa, Florida. Redesigned hardware frontends feature four wideband RF frequency bands that can be split into a maximum of eight sub-bands per unit. At the same time the bandwidth has been expanded to a full 55 megahertz, offering additional signal power especially in the Galileo E5 band.

ESA Outlines Efforts to Rescue Wayward Galileo Satellites

Orbits of the fifth and sixth Galileo satellites launched together on August 22, 2014, in red, compared to their intended position, in dashed green, and the position of the four IOV satellites launched in 2011 and 2012 in solid green. This view looks down over Earth’s South Pole, helping to illustrate how the two satellites’ orbital inclination relative to the equator is less than was intended ESA illustration.

The European Space Agency (ESA) released dramatic illustrations today (September 16, 2014) of the orbital locations of the two errant Galileo spacecraft launched on August 22, the intended orbit, and the locations of four In-Orbit Validation (IOV) satellites.

Air Force Weighs Switching to Multiyear GPS Procurements

The Air Force says it might ask Congress for permission to implement bigger buys of GPS satellites beginning in fiscal year 2016 (FY16) once it sorts out whether to drop Lockheed Martin as the GPS III prime contractor and switch to a different manufacturer for the navigation payload.

The department told Congress in a recent report on multiyear procurement (MYP) that while its current approach “allows the government the flexibility to adapt to a changing budget profile and constellation needs, it prevents the program from realizing savings that MYP could provide.”
