Using dual frequency phase measurements and corrections the cost effective and real time OmniSTAR.HP solution provides a robust and reliable decimetre level GPS service anywhere within the coverage area. Through use of dual frequency GPS receivers the true ionosphere delay can be measured at the reference and user location, thus eliminating this error.
OmniSTAR.HP utilises ionosphere free phase measurements with wide area network reference station correction information to generate positioning results of unmatched accuracy and performance. OmniSTAR.HP accuracies have been demonstrated as better than 10cm 95% (2sigma).
OmniSTAR is the global market leader in providing positioning data and is at the forefront in the design and development of Differential GPS positioning technology.
