CR-G5

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

Ultimate network performance: Ultra-reliable and rugged geodetic grade antenna for network applications.

If you are 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 requirements.

  • 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-centre stability in vertical over expanded GNSS frequency band

CR-G5 is perfect for:

  • Land Surveying
  • Topography & As-Built
  • OEM Manufacturing

Build a network you can trust

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.
