SE873K5

The SE873K5 is a multi-constellation receiver in 7x7x2.25 mm QFN-like package including embedded Flash memory, RTC, TCXO. SE873K5 is able to track and navigate simultaneously all four GNSS constellations (GPS + Galileo + Glonass + Beidou). The SE873K5 provides GNSS information over a serial port (UART, I2C, or *SPI interface supported) using the NMEA protocol, and its low power-processing core delivers customizable power-saving modes to optimize current draw for the desired use case. The receiver supports both local and server-based Assisted GNSS (A-GNSS) for improved TTFF. 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 syntethic ephemeris storage.
