The AST - 500 is a Multi GNSS baseband Receiver SOC which handles the signals fromGPS, GLONASS, NavIC, BeiDou, GALILEO, QZSS and GAGAN (L1/L2/L5 and S band) constellations.

The dual band reception capability of this chipset provides robust positioning performance with elimination of ionosphere errors. The multi-GNSS capability coupled with wide bandwidth signal processing brings superior navigation performance in urban settings. The SoC also features secure boot and data encryption offering an end-to-end secure solution.

The SoC supports configurable interface options like CAN, UART, SPI, I2C and GPIOs, facilitating integration into multiple application platforms.
