Altus - Model APS-3 - Precision Satelite Surveying Positioning Systems Brochure

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).
