TerraStar land DGNSS services can be used for precise positioning at all stages of onshore hydrocarbons exploration and production, from initial reconnaissance, planning and seismic acquisition programmes, to drilling, pipelaying and facilities layout and construction. TerraStar receiver and processing capability is now fully integrated into a range of TerraStarcompatible receivers including pole mounted survey and vehicle mounted units. These are available from several TerraStar
Seismic acquisition benefits especially from the use of TerraStar for the initial layout, and TerraStar-D can be used for the positioning of the recording and source vibrator vehicles during the acquisition operations. There is a clear benefit for the efficiency of these survey intensive operations through the reduction of the need for RTK base stations and their progressive coordination and re-coordination during geographically large acquisition programmes, which may involve 15-20 recorder and vibrator vehicles, and numerous surveyors. With the embedding of the TerraStar receiver technology directly into the GNSS receivers, the resulting physically small and robust package is easily integrated directly onto the recorder and vibrator trucks, feeding high accuracy positioning continuously and directly into the vehicle tablet PCs, vibrator electronics packages and the radio network. The antenna can be directly mounted on the vibrator pad structure.
