摘　　要：在研究利用GPS的高精度载波相位问题中,GPS超短基线解算是一个研究热点,但是多集中于GPS双差模型设计、整周模糊度搜索算法、精度分析和论证等方面。从工程实用的角度出发,通过在不同环境多次对GPS超短基线解算的实测,分析了影响GPS超短基线解算成功率的若干因素。总结出了由载波相位周跳、可用星数和观测环境等因素影响GPS基线解算成功率的一般性规律,对于GPS工程实践具有指导意义。The problem of solving GPS super short baseline has been received considerable attention recently, but most researches focused on model designing, ambiguities search algorithms, accuracy analysis and evolvement. In this paper, some factors that effect GPS baseline solution are discussed and analyzed in detail based on experiments results of GPS baseline calculation in different environments which include carrier phase cycle slip, visible satellite number and observation environment etc. Finally, some general rules for engineering applications are summarized.
