CR-G5

    Next Generation Full Wave Geodetic Antenna

    The CR-G5 is a newly designed choke ring antenna based on Topcon’s new TA-5 full spectrum GNSS antenna element. The TA-5 antenna element utilizes an array of vertical convex dipoles. 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.

    Features:

    • Competitive high-end Geodetic Antenna
    • Topcon’s TA-5 vertical convex dipole antenna element for full spectrum GNSS signal tracking
    • Topcon designed choke ring groundplane
    • Environmentally robust and sealed
    • Improved phase center stability in vertical over expanded GNSS frequency band.

    CR-G5 Full Wave

    The CR-G5 Full Wave Geodetic Antenna replaces the CR-G3 antenna and supports more signals and constellations. The CR-G5 is a newly designed choke ring antenna based on Topcon’s new TA-5 full spectrum GNSS antenna element. The TA-5 antenna element utilizes an array of vertical convex dipoles. This new antenna provides Full Wave tracking technology for existing and future GNSS signals including:

    • GPS
    • GLONASS
    • Galileo
    • Compass
    • QZSS

    The antenna addresses the evolving requirements for reference networks and infrastructure monitoring applications.
