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.

Successful GPS Block IIR-M Spacecraft Launch

Launch of GPS Block IIR-M satellite, October 17, 2007

A Block IIR-M GPS satellite was launched successfully today (October 17, 2007) from Cape Canaveral Air Force Station, Florida. Expected to be set healthy for use in early November 2007, the spacecraft will be designated as PRN15/SVN55, referring to its pseudorandom noise code and space vehicle number, respectively.

Lack of Launcher Module Delays Galileo Launch

Lack of Launcher Module Delays Galileo Launch

GIOVE-A satellite with Fregat module

Unavailability of an upper stage of the Soyuz launcher will delay launch of the second Galileo In-Orbit Validation Element satellite (GIOVE-B) until at least March 2008. The most recent schedule had called for a late-December launch from the Baikonur Space Center in Kazakhstan.

Already behind schedule as the result of an electrical short that caused widespread damage to the spacecraft during laboratory tests in summer 2006, the Galileo program’s latest postponement reportedly stems from the lack of a Fregat module. Fregat is the portion of the Russian rocket that releases the spacecraft into its final orbit (shown with GIOVE-A in accompanying ESA photo).

Transport Ministers Leave Galileo Procurement Unresolved

Transport Ministers Leave Galileo Procurement Unresolved

The European Transport Council generally reaffirmed its commitment to the Galileo program in an October 2 meeting without resolving some underlying differences of how to finance the system following abandonment of the public-private partnership (PPP) approach earlier this year.

In its first look at the European Commission (EC) plan to complete the system by 2013 under a more traditional public procurement process, the council confirmed its intention “to take an integrated decision on the European GNSS before the end of the year.”

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

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.

Block IIF Satellite Heads for Key Tests

Block IIF Satellite Heads for Key Tests

Boeing technicians and first Block IIF satellite

The Boeing Company has successfully assembled and integrated all flight hardware onto the first GPS Block IIF (follow-on generation) satellite. Launch is now scheduled for the second half of 2008.

GPS llF spacecraft will bring new capabilities to the GPS constellation, such as a new encrypted military code, a new civil signal, crosslink enhancements, increased signal power, and longer design life. Boeing is building 12 GPS Block IIF satellites under contract from the GPS Wing at the Space and Missile Systems Center at Los Angeles Air Force Base.

NovAtel Confirmed for Long-Term Galileo Contracft

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).

GLONASS has “preliminary approval” to transmit CDMA GLONASS signals at L1, L5

GLONASS has “preliminary approval” to transmit CDMA GLONASS signals at L1, L5

GLONASS has gotten “preliminary approval” to add code division multiple access (CDMA) signals to future satellites.

Since its initiation in the early 1980s, the Russian GNSS system has employed frequency division multiple access (FDMA) techniques in which the same code is used for the signals broadcast by the system, with individual spacecraft being distinguished from one another by a specific frequency allocation. Russia would almost certainly continue broadcasting FDMA signals on existing frequencies.
