Telit’s Jupiter SE868-V3 module. Telit Wireless Solutions has released a new GNSS module, the SE868-V3. The positioning module combines GPS, GLONASS, Beidou, Galileo and SBAS, which enables the creation of high-performance position reporting and navigation solutions. The SE868-V3 can navigate to -162 dBm and track to -166 dBm, providing improved performance in harsh environments. It is pin-to-pin compatible with the former SE868-V2 as well as the JF2. This advanced GNSS module can track GPS and GLONASS or GPS and Beidou constellations simultaneously and it is Galileo-ready. The 11 x 11 mm QFN package contains a powerful baseband processor, SQI Flash memory and GNSS chip with integrated low noise amplifier (LNA). The ultra-sensitive RF front-end enables multi-GNSS indoor fix and high-quality navigation in challenging outdoor scenarios such as dense urban areas, Telit said. In addition, the SE868-V3 supports ephemeris file injection (A-GPS) as well as Satellite-Based Augmentation System (SBAS) to increase position accuracy. Its onboard software engine is able to locally predict short-term ephemeris starting from data broadcast by GNSS satellites received by the module and stored in the internal Flash memory. “The SE868-V3 is yet another addition to our positioning product portfolio, which is the result of over 20 years of experience in GNSS applications,” said Felix Marchal, chief product officer, Telit. “Our products are compatible with the GPS constellation as well as its Russian counterpart GLONASS and China’s Beidou.”
