GPS Budget On Track for Near-Full Funding

Senate Seeks Report on OCX Alternative

Both the Senate Appropriations Committee and the Senate Armed Services Committee have now passed their spending bills, largely agreeing with the White House and their House counterparts on funding levels for the GPS program with the exceptions of nearly tripling the House cut to the GPS IIIF program and taking a shot across the bow of the new GPS ground system.

FAA Now Has Improved GPS Coverage Across U.S. as GEO 5 joins WAAS

The Federal Aviation Administration’s Geosynchronous Earth Orbiting 5 Wide Area Augmentation System (WAAS) navigation payload, developed by Raytheon’s Intelligence, Information and Services business, is now operational and fully integrated into the WAAS network. The GEO 5 payload joins two others already on orbit in correcting GPS satellite signal ionospheric disturbances, timing issues, and minor orbit adjustments, giving users increased coverage, improved accuracy, and better reliability.

GPS IIIF: The Air Force Decides to Stick With Lockheed

Over at least half a dozen years the GPS III Follow On program has taken a number of dramatic turns only to wind up, in true soap opera fashion, with the same leading characters headed to the altar.

At the end of the latest episode, the field of suitors for the multi-billion-dollar GPS IIIF contract narrowed suddenly in April when two of the three corporate hopefuls abruptly left the field.

Letter About Ligado in Limbo

The issue at hand is whether the Federal Communications Commission (FCC) should allow a change in the use of frequencies close to those used by GPS. Virginia-based Ligado Networks wants to repurpose its satellite frequencies to also support ground-based telecom services. Testing done several years ago and expanded upon more recently has shown such a system could seriously interfere with GPS receivers.

Some three months after a meeting of the key federal agencies using and running the GPS program, they have yet to release a letter stating their recommendation on whether to allow the development of a potentially interfering telecommunication service.

Broadgnss Releases High Precision GPS Receiver

Broadgnss Technologies recently announced at the 9th China Satellite Navigation Conference a new high precision satellite position receiver with patented RAC(Real-time Array Calibration) technology. It features positioning accuracy better than one meter (up to 10 centimeters). By receiving only single frequency (GPS L1) satellite signals, the RAC technology in high precision satellite positioning frees the dependence on traditional augmentation network and significantly reduces the cost to enable high precision satellite positioning to enter large-scale applications, according to the company.
