RTK GPS在钻井平台对接定位引导中的应用

Application of RTK GPS for Rig Alongside Jacket on Offshore Survey Engineering

RTK GPS的主要功用是进行相对定位,移动台之间以及其与基站间的基线向量具有很高精度和稳定性。讨论了由RTK GPS组成的定位引导系统的组成及工作原理,并给出基线长和方位的求解公式,用以取代传统的海上光学交会测量,为海上对接工程提供更加方便快捷、稳定可靠和实时的高精度测量和定位引导,确保对接工程作业安全。

The main function of RTK GPS is at relative survey. The baseline vector between base and mobile station has high precision and stability. This paper provides the formulae of base line length and azimuth and discusses the structure and principle of survey system. Instead of the conventional photics survey, this system can provide survey and position for rig alongside jacket with high conveniency, rapidness, credibility and stabilization.
