10 cm High Performance
The OmniSTAR HP service is the most accurate solution available. It is a L1/L2 solution requiring a dual frequency receiver. Data from OmniSTAR’s network of reference sites is utilized together with atmospheric corrections. Carrier phase measurement is used to maximize accuracy. OmniSTAR HP will usually have a 2-sigma (95%) horizontal error of about 6 centimetres and a 99% horizontal error of less than 10 centimetres. It is particularly useful for Agricultural Machine guidance and many surveying tasks. It operates in real time and without the need for local Base Stations or telemetry links. OmniSTAR HP is a true advance in the use of GPS for on-the-go precise positioning.
