V-Flex Mobile and Base
DOWNLOAD SPEC SHEET>

V-flex mobile is a new development of DGPS 4u Ltd. It is a totally flexible system, you can start off with just normal DGPS using the EGNOS SBAS Free Service.

As you progress and need better accuracy for drilling or using auto-steer, you have the option to change from DGPS to RTK L1 Or RTK L1 / L2 by software upgrade but still retaining same housing, power supply, cable, antenna etc. A UHF radio Modem is added to receive the correction, which slides into the housing making it a very compact RTK all in one system.The GPS antenna and UHF antenna are combined in one unit (No other company currently offer this type of combined antenna in the agricultural market).

VFlex Guidance systm for agricultural machinery
By building on the system you are using, you are taking on step at a time. By using the next option RTK it is not necessary to have auto-steer. You can use your normal guidance system (Jethro etc) with RTK but with manual steer etc, for your drilling etc. You will need a base station whichwe can also supply with the system range is 10Km or more depending on what the terrain is and which RTK system you use, you can also lock into local RTK network if one is available.
