摘要(Abstract)：

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。
