1、石油工程GNSS精密单点定位研究及软件研发贺凯飞卢晓鹏刘加收张彪张林杰鲁洋为中国石油大学（华东）地球科学与技术学院湖州市城青岛中油岩土工程有限公司针对传统的GPS和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申系统的稳定性、观测值数B及质量。随着我国北斗导航定位系统（BDS）的发展，使得GNSS多系统口趋完善，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

2、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宄，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,白主研发丫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。关键词：石油工程;GPS;GLONASS
