Fastrax integrates GPS, Glonass in GNSS receiver module

Fastrax Ltd. said it has integrated GPS, Russian-based Glonass, Japanese QZSS and SBAS in a single receiver module. In addition to Global Navigation Satellite Systems, the IT600 will support other positioning systems such as European-based Galileo and Chinese Compass/Beidou2 in the future.

Fastrax IT600, designed to address the automotive market, is based on the newly introduced STMicroelectronics' Teseo II GNSS chipset (STA8088EX).

The chip is an advanced multi-constellation positioning receiver IC. It has an embedded RF input with separate GPS/Galileo and GlonassIF outputs combined with 32 dedicated tracking channels that can be assigned to acquire and track any mix of GPS, Galileo, QZSS and Glonass signals.

Unused tracking channels can be turned off for power saving. Enabling Glonass in urban canyons with limited visibility of the sky, the number of visible satellites go up typically with a factor of two compared to, for instance a GPS-only receiver. IT600 is also Galileo and Compass/Beidou ready with future software upgrades.

IT600 offers a wide range of interfaces in a tiny form factor. Two UART’s are available for NMEA and RTCM104. A third UART/USB is also available. I2C provides a convenient interface for adding for instance MEMS sensors, EEPROM or other I2C compatible peripherals. A standard 1PPS output is also available. CAN bus is available for DR. The I/O voltages are 3.3V CMOS levels.

Fastrax IT600 features:
. Multi GNSS support (GPS/Galileo and Glonass)
. DR support (Odometer/Gyro or CAN DWP)
. Small form factor –16.2mm x 18.8mm x 2.3mm
. Low power consumption: 80 – 150mW
. Ultra High Sensitivity -162 dBm (Tracking)
. Cold start sensitivity -146dBm
. I2C for MEMS sensors and other I2C peripherals
. Three serial ports
. 1PPS output
. SPI and GPIO available for custom purposes
. AGPS & PGPS support
. Anti-Jamming detection and removal
. JTAG for SDK and debugging

Samples of the module are expected to be available in Sept. 2011.
Volume production is estimated to start in Oct. 2011.
