What is VRS?
RTK VRS is a correction signal delivered to the tractor or combine by using the GPRS mobile phone network. The actual data exchange is done by a SIM card & GPRS modem mounted in the vehicle cab. The correction data comes from a central Trimble VRS NowTM server which is continually monitoring and analysing data from 115 RTK Base stations.
