The U.S. Air Force launched the fifth modernized GPS Block II Replenishment (IIR-M) satellite at 3:04 p.m. EST (20:04 UTC) December 20 from Cape Canaveral Air Force Station, Florida, (December 20) aboard a United Launch Alliance Delta II rocket. Air Force controllers set the spacecraft to "healthy" status on January 2, in what is probably a record time of 13 days.

Finland’s farflung mobile phone manufacturer Nokia and Dutch personal navigation device (PND) vendor TomTom continue to make progress toward their multi-billion-dollar acquisitions of navigable digital mapmakers Navteq and Tele Atlas, respectively. But a regulatory challenge in Europe may complicate TomTom’s effort, while Nokia appears likely to sail through unchallenged in the United States.

Inside GNSS • November/December 2007
More and more GPS-enabled devices are entering the consumer marketplace, many incorporating assisted-GPS (A-GPS) technology. These include not only cellular phones, but laptop datacards, PDAs, and other mobile equipment.
Increasingly, GPS devices that were previously standalone now incorporate a cellular modem for such applications as mapping download or live traffic alerts. The proliferation of GPS in the consumer space can also be seen in the availability of GPS automotive navigation systems in local supermarkets or large grocery stores.

Space weather accounts for the most substantial errors experienced by GPS/GNSS systems and their users. It is the single largest contributor to the single-frequency GPS error budget, and a significant factor for differential GPS.
But exactly what is space weather? And how does it affect satellite navigation systems?

Thinking Aloud • November/December 2007
Technology-agnostic. Now there’s an interesting term.
I first heard it from engineering staff at the Federal Communications Commission as they backpedaled away from a premature assumption that network-based solutions would meet the agency’s E911 mandate for wireless phones. After, that is, their assumption was confronted with a more accurate, more far-reaching GPS technology.

Even as the fate of the inland portions of the Nationwide Differential GPS (NDGPS) reference network hangs in the balance, the U.S. Coast Guard (USCG) has awarded a contract to Trimble for up to 400 high-accuracy GPS reference receivers.
The Trimble NetRS reference receivers will be installed over the next three years as part of the coast guard’s modernization of the Maritime DGPS Service, which is not part of the NDGPS elements that being considered for termination.
