GEM1105-4040A00
GEM1105 is a high performance single-band RTK module with built-in antenna, which is based on TAU1308.
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 raw data output, easy for 3rd party integration
- The best cost-effective high precision GNSS positioning solution integrated with antenna
