STMicroelectronics offers the first GNSS modul (Global Navigation Satellite System) called Teseo-LIV3F.
The module could be interesting for your project beacuse it contains a few useful features.
The GNSS module supports GPS, Galileo, GLONASS, QZSS and also BeiDou.
The dimension of module is 9.7 x 10.1 mm and the communication interface is standard UART and I2C (100/400KHz).
The Teseo-LIV3F module contains temperatured-compensated 26 MHz oscillator for higher quality data receipt.
Except of this feature you can use real-time clock (RTC).
The I2C address is configurable through “firmware configurator” (PC Tool Teseo-Suite Light). The The firmware of module can be easily updated.
The power consumption of GNSS module can be affected by two standby modes – software and hardware standby.
When you use hardware standby mode, the consumption is wonderful 6 uA, if you use software standby mode you achieve the power consumption only 12 uA.
The module also contains “data logging” feaure.
The position data can be saved up 12 hours with 1 Hz and you can use standard or circular buffer.
Teseo-LIV3F contains odometer, the measurement of distance.
