The GB-500 provides advanced Topcon dual-frequency, dual-constellation, GPS+ receiver board design inside a rugged, compact housing featuring a simple MINTER display with LEDs providing satellite tracking, battery, and recording status.
The GB-500 features:
At its core is our Paradigm® chip featuring 40 universal channels capable of tracking L1 and/or L2 frequencies for both GPS and GLONASS satellite systems. It incorporates our new innovations in signal processing, multipath mitigation and co-op tracking, making Topcon GPS+ the best in the field for under-canopy and low signal strength reception.
