The combination of a compact form factor, revolutionary Universal tracking technology, and multiple communication methods makes the Topcon GR-5 receiver the most popular and versatile option for high precision GNSS reliability.

  • Capable of tracking GPS, GLONASS, BeiDou, Galileo, QZSS constellations
  • Universal Tracking Channels capable of all-in-view tracking
  • Track every satellite constellation above today and tomorrow
  • Signal scrubbing Fence Antenna® to provide ultimate signal lock
  • Highest accuracy positioning for RTK, network, and more

RELIABLE AND PRECISE POSITIONING SOLUTION

The internal technology within Topcon's GR-5 receivers is small and out of sight, yet brings a powerful punch with the ability to listen and track each satellite available today and tomorrow. The Topcon GR-5 receiver harnesses the processing horsepower and intelligence of Topcon’s 226-channel Vanguard chip. Instead of dedicated channel assignments to track a particular signal or satellite, Topcon's Vanguard technology is smart enough to efficiently manage any signal of any constellation for you at speeds like you have never seen before.
