Trimble Snares USCG DGPS Contract; NDGPS Imperiled

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.

STM Launches 32-Channel GPS Processor

STMicroelectronics has introduced Cartesio, its new automotive-grade application processor with embedded GPS for navigation and telematics. The processor couples with ST’s GPS RF chip (STA5620) to provide a core receiver unit.

Cartesio (STA2062) integrates a 32-bit ARM CPU core with a high-sensitivity 32-channel GPS subsystem and a large set of connectivity peripherals, including CAN, USB, UARTs, and SPI. It also provides on-chip high-speed RAM and real-time clock functionality, according to the company.

Cornering the Market on Navigable Maps? Nokia/NAVTEQ, TomTom/Tele Atlas Deals

The stunning sequence of multi-billion-dollar buyout offers for the two leading navigable map data providers TeleAtlas and NAVTEQ — by TomTom and Nokia, respectively — raises issues not only of access to critical intellectual property (IP) and a long-delayed explosion of location-based services (LBS) but may also determine the outcome of the long-debated platform of choice for GNSS-enriched consumer applications.

NovAtel Confirmed for Long-Term Galileo Contracft

Thales Alenia Space Italia (TAS-I) has awarded NovAtel Inc. a €440,000 milestone award for continued development of the Galileo ground reception Chain (GRC) reference receiver. Although the incremental size of the award is modest, the agreement provides for confirmed, longer-term funding of a two-year-old contract valued at €6.3M (US$8.6 million).

Sunspots Blank GNSS Receivers

Researchers at Cornell University recently released their analysis of the effects of solar radio bursts (SRBs) during a solar flare last December that produced “unprecedented” fades in received GPS signal power at L1 and L2 over an extended period.

Galileo Plods On

Europe’s Galileo program continues to take small steps as it waits to see if it can get through an impasse between the European Commission (EC) and the consortium of companies seeking a concession to complete and operate the Galileo system.

Russia Labors to Bring Latest GLONASS Satellites On Line

The Russian Space Forces are continuing efforts to bring the final two GLONASS spacecraft launched December 25 into operation.

One of the trio of satellites (SV798 in slot 19) went on the air in late January. Reports from the Russian news agency RIA Novosti, quoting Russian space officials, subsequently attributed the delay to frozen fuel lines in the satellites.

GPS L2C is on the air

Civil GPS users now have a second full signal available to them — albeit on only one satellite and “at the user’s own risk” — courtesy of the first modernized Block IIR (IIR- 14M) spacecraft launched last September. And the world’s geodetic community is already moving to take advantage of it with announcement of an addendum to the receiver autonomous exchange (RINEX) format used to combine high-precision position data from different types of GPS receivers.
