CR-G5

Ultimate network performance

Ultra-reliable and rugged geodetic grade antenna for network applications

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

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

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.
