摘要
实时精密单点定位(PPP)是一种经济高效的高精度海上定位技术。随着海上精密作业深入发展,除定位精度外,对于海上高精度位置服务的可靠性要求不断提高。精密单点定位完好性监测是海上精密作业高精度定位的可靠性保障。为此,通过构建接收机端高级自主完好性监测算法,建立严格完好性保障的海上精密单点定位误差界限,保障了海上多重干扰条件下的高精度定位可靠性性能。本文依托南海某DP动力定位钻井平台开展远海钻井作业,实测结果表明,北斗/GPS PPP收敛定位精度可达10 cm,危险误导信息概率满足10^(-7)水平,连续性风险概率满足10^(-6)水平。
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.
