Note : Your request will be directed to Quectel.

The LC79D from Quectel is a Multi-Constellation GNSS Module that simultaneously supports L1 and L5 bands for GPS, Galileo and QZSS satellites. It uses the L1 band for GLONASS and BeiDou satellites and the L5 band for IRNSS. Based on Broadcom's BCM47755, this AIS-140 compliant module has an integrated LNA and SAW filters. It can provide positioning accuracies near 1m in weak signal areas and has excellent performance in deep urban canyons. The module has an acquisition sensitivity of -147 dBm and tracking sensitivity of -162 dBm. It is available in an ultra-compact package that measures 10.1 x 9.7 x 2.4mm with SPI, UART, and I2C interfaces. The LC79D is suitable for IoT, tracking, precision agriculture, and drone applications.
