Study Launched to Quantify the Economic Benefits of GPS

Irving Leveson

A new study is underway to estimate the economic benefit of GPS and quantify what’s at stake if anything interferes with its navigation signals.

Launched at the request of the National Executive Committee (ExCom) for Space-Based Positioning, Navigation, and Timing (PNT), the first segment of the two-part study would look at major uses of GPS. It will estimate the benefits derived from the system and describe the costs that would be incurred if GPS became unavailable, compiling the results in an interim report.

Errant Galileo FOC Satellite Signal Helps Provide First Positioning

Galileo satellite geometry and received signal strength for the December 9 fix using the first Galileo FOC satellite, as received by the Septentrio Test User Receiver at ESTEC. The first Galileo FOC satellite corresponds to E19 on the left display; IOV PFM to E11, IOV FM2 to E12 and IOV FM3 to E19. ESA figure

Galileo’s fifth satellite (and first fully operational capability, or FOC, spacecraft) — recently salvaged from an incorrect orbit  — has been combined with three predecessors to provide its very first position fix.

Test receivers at the European Space Agency (ESA) ESTEC technical center in Noordwijk, the Netherlands, and at the Galileo In-Orbit Test station at Redu, Belgium, received the signals at 12:48 GMT on December 9 from a quartet of Galileo satellites and fixed their horizontal positions to better than two meters.

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.
