The SL871 represents a new age of receiver that can simultaneously search and track satellite signals from multiple satellite constellations. This multi-GNSS receiver uses the entire spectrum of GNSS systems available: GPS, GLONASS, Beidou, Galileo and QZSS. Operation in a high interference signal environment is common practice in today’s electronic age. By incorporating embedded interference suppression, the SL871 is able to remove interfering signals pre- and post-correlation.Operating on a single 3.3V power supply, this module combines a GNSS engine, TCXO, SAW Filter, RTC and LDO. Communication is done over a UART serial port using NMEA message format. As a the Standard GNSS Module, the SL871 offers high sensitivity, low power consumption, jamming immunity and fast time to first fix. As a Timing Module, the SL871 provides best-in-class timing performance with an extremely stable synchronized 1PPS output.
