| 摘 要： | 深水动力定位(DP)石油钻井平台依赖于高精度的位置参考基准，精密单点定位(PPP)技术是提供海上高精度位置服务的首选方式。目前海上石油钻井平台DP系统所需的高精度位置参考基准以GPS为主。随着我国北斗卫星导航系统(BDS)的全球组网，BDS实时PPP必将为全海域作业提供自主高精度的位置参考基准。本文就自主研制的BDS实时PPP产品开展实船应用研究，并接入南海作业的某DP系统。结果表明，相比于国外同类产品，收敛后的三维位置差异性小于50 cm，接入DP系统后BDS与GPS信息所占的权值一致，验证了BDS单系统实时PPP在海洋石油钻井平台DP系统应用的可行性。

| Abstract: | The dynamic positioning (DP) offshore drilling rig depends on the high precision position reference datum. Precise point positioning (PPP) technology based on global navigation satellite system is the best choice to provide ocean high precise position service. At present, the high-precision position reference datum of offshore drilling rig mainly depends on GPS. With the completion of BeiDou Navigation Satellite System (BDS), the BDS real-time PPP will provide independent and high-precision position reference in the global ocean. In this paper, a self-developed receiver based on BDS real-time PPP is carried out and connected to a DP system in the South China Sea. The results show that compared with similar GPS receiver, the three-dimensional position difference after convergence is less than 50 cm. Meanwhile, the weight of BDS and GPS information is the same in Kongsberg DP system. It verifies the feasibility of DP offshore drilling rig operation based on single BDS position reference datum. |
