GEM1305 dual-band RTK smart antenna

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
