Topcon CR-G5 GNSS antenna

Topcon Positioning Systems (TPS) announced the company’s new CR-G5 high-performance, GNSS choke ring antenna.

Based on the company’s new TA-5 full-spectrum GNSS antenna element, the CR-G5 geodetic antenna offers excellent vertical phase center stability over the GNSS frequency band superior performance in tracking low elevation satellite signals, according to the company.

Based on the company’s new TA-5 full-spectrum GNSS antenna element, the CR-G5 geodetic antenna offers excellent vertical phase center stability over the GNSS frequency band superior performance in tracking low elevation satellite signals, according to the company.

The TA-5 technology utilizes an array of vertical convex dipoles to provide “full wave” tracking for all existing and future GNSS signals. A “white paper” on the TA-5 can be found on-line in Inside GNSS’s eLibrary here. The antenna element possesses a relative bandwidth that more than covers the entire GNSS band from 1160 up to 1615 MHz.

The CR-G5 is designed for the long-term installations required for reference network and monitoring applications. The unit is shock tested to withstand repeated one-meter drops onto concrete, and meets environmental ratings for IPX7 (waterproof) and IP6X (dustproof), Topcon sources say.
