CR-G5 Full Wave
The CR-G5 Full Wave Geodetic Antenna replaces the CR-G3 antenna and supports more signals and constellations. The CR-G5 is a newly designed choke ring antenna based on Topcon’s new TA-5 full spectrum GNSS antenna element. The TA-5 antenna element utilizes an array of vertical convex dipoles. This new antenna provides Full Wave tracking technology for existing and future GNSS signals including:
- GPS
- GLONASS
- Galileo
- Compass
- QZSS
The antenna addresses the evolving requirements for reference networks and infrastructure monitoring applications.
