Fixed Base RTK

LH Agro’s bespoke RTK fixed base solution incorporates a Topcon GB-3 survey grade G3 RTK receiver with a G3-A1 antenna, linked to a 35W Digital UHF radio transceiver and 6db gain omni-directional antenna giving ultimate coverage across the base operational area*.

The Topcon GB-3 features the latest 72 Universal Channel G3 Technology capable of receiving signals from all present and future satellite constellations GPS, GLONASS and Galileo. The GB-3 can be configured to output either CMR or RTCM 3.0 correction packets.

As part of your RTK package, we can offer a variety of different mast options to suit your location. Building mounted masts are mounted to an internal vertical RSJ. Masts using grain storage/silo facilities are mounted to the supporting steel framework. We can also supply free standing lattice masts where no structure is available.
