Complete GNSS receiver module with extreme performance
|Fastrax IT600 key features|
OEM receiver for Automotive Applications
IT600 is Fastrax solution to address Automotive market. It uses STA8088EX IC from ST. Optionally an AEC-Q100 automotive qualified IC from ST can also be used (STA8088EXA). Manufacturing is done in an ISO/TS 16949 qualified site. Qualification tests on IT600 module are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”
IT600 supports DR using traditional 1-axis analog Gyro and Odometer Pulse from car. Support for DWP (Differential Wheel Pulse) based DR through CAN interface will be available later.
Multi GNSS Support
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. This means that your fix is guaranteed in most cases. 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.
IT600 supports Assisted-GPS technology, able to provide both fully-autonomous Ephemeris prediction and server-based, predictive assistance using GPStreamTMServer technology provided by Rx Networks. The autonomous predictions are providing accurate fix for 5 days on observed satellites with no server needs.
Using server-based GPStreamTMtechnology from Rx Networks, the access of a very compact information (2KB payload) ensures full-constellation predicted ephemeris valid for 7 days.
A JTAG interface is also available for custom firmware implementations and debugging. Currently ARM Realview 3.1 compiler and Lauterbach ICE are supported. Support for GNU compilers will be available later.
