CR-G5

Ultimate network performance

Reliable and rugged geodetic-grade antenna for network applications

Product Info

High-accuracy GNSS choke ring antenna designed for all CORS environments

If you’re establishing a new CORS network or upgrading an existing service, the CR-G5 is the perfect antenna for all high-accuracy 24/7 GNSS signal reception needs.

  • High-end geodetic antenna
  • TA-5 vertical convex dipole antenna element for full-spectrum GNSS signal tracking
  • Topcon-designed choke ring ground plane
  • Environmentally robust and sealed
  • Improved phase-center stability in vertical over expanded GNSS frequency band

 

Build a network you can trust

Utilising an array of vertical convex dipoles, we designed the CR-G5 full choke ring antenna 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.
