Abstract

Abstract: Real-time precise point positioning is a cost-effective high-precision marine positioning technology. With the development of offshore precision operations, in addition to positioning accuracy, the reliability requirement for offshore high-precision position services has increased. The integrity monitoring of precise point positioning can ensure the high-precision reliability of offshore precision operations. Therefore, by constructing the advanced receiver autonomous integrity monitoring algorithm, the error limit of PPP at sea with strict integrity guarantee is established, which ensures the reliability of high-precision positioning under the condition of multiple interference. The actual measurement results of offshore drilling operation relying on a drilling platform show that the convergence positioning accuracy of BDS/GPS PPP can reach 10 cm, the probability of hazardous misleading information can meet the 10^-7 level and the continuity risk can meet the 10^-6 level.
