Ultra high sensitivity is 162dBm (tracking) and cold start sensitivity is rated at 146dBm
The IT600 utilises the STA8088EX integrated circuit from ST providing a suitable solution to the automotive tracking market. 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.
