The SE873K5 from Telit is a Multi-Constellation GNSS Receiver that can track and navigate all four GNSS constellations (GPS + Galileo + Glonass + Beidou) simultaneously. It has an acquisition sensitivity of up to -146 dBm and tracking sensitivity of up to -163 dBm. This GNSS receiver provides positional information with an accuracy of better than 1.5 m and includes a jammer detection feature. It has an integrated TCXO, RTC & flash memory and supports both local and server-based A-GNSS for improved TTFFs. This GNSS receiver requires a DC supply from 1.75 to 1.85 V and consumes 58 uW of power in hibernate mode and 37 mW of power in acquisition mode.
The SE873K5 provides GNSS information over a serial port (UART, I2C, or SPI interface) using the NMEA protocol, and its low power-processing core delivers several customizable power-saving modes to optimize current draw for the desired use case. It is available in a QFN package that measures 7.00 x 7.00 x 2.25 mm and is ideal for wearable, light portable devices, and battery-powered solutions.
