The Jupiter SL871 is the representative of a new multi- constellation GNSS module family in the Telit portfolio aiming to be the ideal solution for battery-life sensitive GNSS applications that do not require Dead Reckoning, TRAIM and support of communication ports like USB or CAN bus. The SL871 is designed for global compliance with the whole set of GNSS constellations, either already in place (GPS, QZSS and GLONASS) than under deployment – (Galileo and Compass / BeiDou). The SL871 is capable of tracking GPS + Galileo and GLONASS (or GPS + Galileo and Compass / BeiDou) con- stellations simultaneously, providing the positioning data though standard UART. The SL871 is packaged in a 9.7 x 10.1 mm LCC package with an ARM7 baseband processor, embedded Flash memory and integrated LNA. Its ultra-sensitive RF frontend enables multi-GNSS indoor fix, fast fix and navigation in challenging outdoor scenarios such as dense urban areas.
