中文摘要	针对传统的GPS相对定位模式已不能满足石油工程项目快速发展的需求,如在非洲或沙漠地区,通常难以获取高精度的参考点来进行GPS相对定位,而且GPS单系统则严重依赖于其单系统的稳定性、观测值数目及质量。随着我国北斗导航定位系统(BDS)的发展,使得GNSS多系统日趋完善,使用GNSS多系统精密单点定位方法则可满足现今的石油工程要求。因此,基于目前已建成运行的GNSS多系统(BDS/GPS/GLONASS)对多系统组合的精密单点定位进行了研究,采用精确的时间系统模型,并综合了抗差Kalman滤波估计及Helmert方差分量估计的方法来增强系统的抗粗差能力及合理分配各GNSS系统的权比关系。基于该研究,自主研发了BDS/GPS/GLONASS精密单点定位软件,并采用实测数据对理论及软件进行验证。结果表明,采用BDS/GPS/GLONASS多系统能够有效提高定位结果的稳定性及精度,可为石油工程行业提供定位技术支持。
英文摘要	The traditional method of GPS relative positioning has been unable to meet the request of rapid development of petroleum engineering,such as in Africa or desert areas.It is often difficult to obtain the high-precision reference points for GPS relative positioning,and GPS single system is heavily dependent on its single system stability,number of observations and its quality.With the development of BDS, the GNSS multi-system is becoming perfect,and the method of GNSS multi-system precision point positioning(PPP)can meet the requirements of today’s petroleum engineering project.Therefore,based on the GNSS multi-system(BDS/GPS/GLONASS),the PPP of multi-system combination is studied.The exact time system model is adopted.The system’s anti-gross tolerance and reasonable allocation weight relationship among the GNSS systems is improved by the robust Kalman filter and Helmert variance component estimation method.Based on this research,BDS/GPS/GLONASS PPP software is developed independently, and the theory and software are verified by the measured data.The results show that the BDS/GPS/GLONASS multi-system can effectively improve the stability and accuracy of the GNSS positioning results,and can provide the positioning technology support in the petroleum engineering industry.
