Incredibly rugged and reliable high-accuracy GNSS choke-ring antenna for CORS applications. Utilizing an array of vertical convex dipoles, the CR-G5 is a full choke ring antenna designed for high accuracy networking applications, based on our TA-5 full spectrum GNSS element.
By providing Full Wave tracking technology for existing and future GNSS signals, including Galileo, BeiDou and QZSS, the CR-G5 addresses the evolving requirements for reference networks and infrastructure monitoring applications.
The CR-G5 is a newly designed choke ring antenna based on Topcon’s new TA-5 full spectrum GNSS antenna element. This new antenna provides Full Wave tracking technology for existing and future GNSS signals. The antenna addresses the evolving requirements for reference networks and infrastructure monitoring applications.
