GEM1301 is a high-performance dual-band high precision GNSS positioning module with antenna built-in, which is based on the state of the art CYNOSURE III GNSS SoC chip. It supports BDS-3 signals, along with global civil navigation systems, including GPS, BDS, GLONASS, Galileo, QZSS, and SBAS.
Feature
- Supports GPS, BDS, GLONASS, Galileo, QZSS, and SBAS
- Integrated Real Time Kinematics (RTK)
- State-of-the-art low power consumption design
- Supports multi-band multi-system high precision raw data output, easy for 3rd party integration
- The best cost-effective high precision GNSS positioning solution integrated with antenna
