Everything you need is packed into the BASELINE HD housing – there’s the GPS receiver, a GPS aerial, battery and transmitter. Outside all you see is the radio aerial, aerial clip and the telescopic tripod. The mobile unit is installed quickly wherever it’s needed so you can get on with the job in hand without delay. On the receiving end, the machine is fitted with a roaming box with a built in radio receiver and aerial plus the aerial cable.

The BASELINE HD transmits the correction signal in a range of 3 to 5 km, depending on the topography. Within this radius, any number of machines can run with this signal simultaneously, provided of course that each one is fitted with the roaming unit.
