SE873 GNSS module

SE873 GNSS module Datasheet SE873 GNSS module Product User Guide SE873 GNSS module Evaluation Kit User Guide The SE873 is able to track and navigate simultaneously up to three of the four GNSS available (GPS+Galileo & Glonass or GPS+Galileo & BeiDou). The SE873 contains an internal TCXO, RTC, Flash memory and LNA for high RF sensitivity (up to -165 dBm). The SE873 provides GNSS information over a serial port (UART, I2C, or SPI interface) using either the NMEA or (SiRF) OSP protocol. Its low power-processing core delivers several customizable power-saving modes to optimize current draw for the desired use case. The SE873 supports both local and server-based A-GPS for the GPS and GLONASS constellations, thus improving TTFFs. Satellite-Based Augmentation System (SBAS) corrections from WAAS, EGNOS, MSAS, and GAGAN can be used to increase positioning accuracy. The internal flash memory allows Firmware (FW) updates and customization as well as Extended Ephemeris (EE) storage. Key Benefits World smallest flash based GNSS module Complete GNSS module, including TCXO, RTC, and LNA and Flash memory Full GNSS compliance: GPS, Glonass, Galileo and BeiDou Flexible power management modes allow the user to conserve battery life Ultra-sensitive (tracking) RF front-end Supports both active and passive antennas with internal LNA Supports both local and server-based A-GPS for improved TTFFs Satellite Based Augmentation System (SBAS) corrections increase positioning accuracy QTI SiRFstarV (B02) based Over-the-Air firmware update Battery-friendly 1.8 V GPIO Additional Features Product Features Frequency Band: GPS L1, Glonass L1, Galileo E1 and BeiDou B1 Standards: NMEA and OSP binary SBAS (EGNOS, WAAS, GAGAN and MSAS) capability RTC for efficient power management Jamming rejection Data logging Local and server-based A-GPS Environmental Dimensions: 7 x 7 x 1.85 mm 20-pad QFN package Weight: 0.5 g Temperature range: Operating temperature: -40 to +85°C Storage temperature: -40 to +85°C
