The Loran terrestrial radionavigation system might well be pulled back from its 12-year-long dance on the brink of extinction, while the Nationwide Differential GPS (NDGPS) radiobeacon-based augmentation system may have finally been pushed over the edge.

Successful launch of the second modernized Block IIR satellite, IIR-15(M2), on September 25 and scheduling of another IIR-M launch on November 14 underlines recent progress in the GPS program.
IIR-15(M2), also identified by its space vehicle number (SVN58) and pseudorandom code number (PRN31), will be placed into orbital plane A, slot 2. The U.S. Air Force has designated the satellite to be launched in November as GPS IIR-16/M3, PRN15/SVN55.

The GPS Block IIF program continues to lose ground, with first launch of a satellite now projected as no sooner than May 2008 and as late as January 2009 in a “worst case,” scenario, according to the U.S. Air Force. Program costs are also increasing.

This is what happens when the grandchildren of Mickey Rooney and Judy Garland go out and “rent the old barn and put on a show!”
First, there was an independent Seattle, Washington–based filmmaker named Eric Colley and a screenwriter named Hallie Shepherd who knew about the 150,000 actual GPS-guided scavenger hunts now taking place in 200 countries.

The GPS program appears to be struggling on several fronts recently.
GPS III, the next-generation modernization project for the space and ground segments, is facing renewed uncertainty and possible schedule delays. At the same time, anticipated first launch of the follow-on block of satellites (Block IIF) with the new civil L5 signal has been postponed.

Within weeks of a bilateral working group’s recommendation for a common civil GNSS signal design, the European Galileo and U.S. GPS programs have filed draft interface specifications (IS) or interface control documents (ICDs) for the new signals planned for the L1 frequency (around 1575 MHZ).

The Bush Administration’s Fiscal Year 2007 (FY07) budget proposal for the Department of Defense (DoD), announced in February, allocates $315,314,000 in advanced technology development for GPS, including work on the GPS III program. If approved by Congress, that would represent a sizable increase from the FY06 expenditures of more than $85 million and $33 million in FY05.
