GNSS receiver subsystem IP from antenna to position

The Global Navigation Satellite Systems (GNSS) IP is a fully integrated alignment-free turnkey solution for GNSS enabled SoC devices. The dual channels share a common GNSS RF front-end, frequency synthesizer and other infrastructure, resulting in a small die area and inherent interference free coexistence between the two channels. The GNSS front-end supports concurrent reception of the GPS/GALILEO L1 standard and the GLONASS standard, which results in a faster time for first fix and provides a higher accuracy, reliability and coverage in difficult areas. The dual channel mode supports also concurrent reception of GPS/GALILEO L1 and BEIDOU.

The IP is optimized and silicon proven for modern CMOS technologies and includes dedicated features for interference-free co-existence with on-chip wireless standards like WiMAX/WiFi, Bluetooth, and cellular.

Applications

  • Dual core GPS / GLONASS , GPS / BEIDOU, GALILEO / GLONAS and GALILEO / BEIDOU
  • Multi-standard communication devices
  • Integrated cellular handset devices
  • Navigation devices
