Fastrax IT600 GNSS Receiver Module
Fastrax IT600 GNSS Receiver Module provides ST Teseo II GNSS receiver functionality using the state of the art ST STA8088EX chip. The module provides simultaneous GPS, Glonass, QZSS, Galileo, and Compass (BeiDou 2) open service L1 reception capability. The Fastrax IT600 GNSS Receiver Module supports Dead Reckoning using a 2 or 3-axis digital Gyro, magnetometer, accelerometer, odometer, and DWP. Can BUS hookup is also available for Dead Reckoning. The IT600 also supports AGPS, has 3 serial ports and a 1PPS output.
The Fastrax IT600 module is an advanced multi-constellation positioning receiver IC which has a single RF input with separate GPS/Galileo and Glonass IF outputs, combined with 32 dedicated tracking channels that can be assigned to acquire and track any mix of GPS, Glonass, QZSS, Galileo, and Compass signals. Unused tracking channels can be turned off for power saving. By enabling GPS + Glonass reception, the number of visible satellites typically goes up by a factor of two, compared to, for example, a GPS-only receiver. This means that in urban canyons with limited visibility of the sky, a GNSS fix is guaranteed with higher accuracy when compared to GPS-only receivers. IT600 is also Galileo and Compass ready with future software upgrades.
IT600 supports St Microelectronics ST-AGPSTM Self Trained Assisted-GPS technology, able to provide both fully-autonomous Ephemeris prediction and server-based, predictive assistance using GPStream™ Server technology provided by Rx Networks. The autonomous predictions provide an accurate fix for 5 days on observed satellites with no server needs. Using server-based GPStream™ technology from Rx Networks, the access of very compact information (2KB payload) ensures full-constellation predicted ephemeris, valid for 7 days.
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 MEMS sensors, EEPROM, or other I2C compatible peripherals. A standard 1PPS output is also available, and CAN bus is available for DR. The I/O voltages are 3.3V CMOS levels.
