The Teseo-LIV3F is a standalone positioning receiver IC that works simultaneously in multiple constellations (GPS, Galileo, Glonass, BeiDou and QZSS), being an easy to use GNSS (Global Navigation Satellite System) module. It brings the proven accuracy and robustness of the Teseo chips into the hands of everyone.
Besides being able to integrate this module into your projects, the EVB-LIV3F standalone solution allows you to evaluate its performance using only a computer, pretty easy!
Looking at the specifications of the Teseo-LIV3F, there is:
- Simultaneous multiconstellation
- -163 dBm tracking sensivity
- 1.5 m CEP position accuracy
- Operating voltage range from 2.1 V to 4.3 V
- UART and I2C port available
- Tiny LCC 18 pin package, measuring 9.7 mm by 10.1 mm
- Extended operating temperature range, from -40 ºC to 85 ºC
- Free firmware configuration
- 17 µW standby current and 75 mW tracking power consumption
Aside from the list of specs, there are some other interesting functionalities to highlight: firstly, the on-board TCXO (Temperature Compensated Crystal Oscillator) allows for superior accuracy and a reduced TTFF (Time to First Fix) that relies on its dedicated 32 kHz RTC (Real Time Clock) oscillator. Other interesting feature is the embedded 16 Mb flash memory, which enables the chip to offer many interesting extra functionalities, such as data logging, 7 days autonomous assisted GNSS, besides firmware reconfigurability and upgrades. The Teseo-LIV3F also provides the Autonomous Assisted GNSS, which enables it to predict satellite data based on previous observation of the satellite. Lastly, the module is a certified solution, that optimizes the time to market of the final applications, with a wide operating temperature range.
