摘要
提出一种网络RTK的基准站 (一般相距几十公里或上百公里 )单历元双差模糊度搜索方法 ,并详细地给出该方法的数学模型、方法步骤与数据检验结果。该方法的主要思想为 :使用双频GPS载波相位数据 ,不需解算双差观测方程组 ,直接利用测站坐标已知、模糊度为整数和双频模糊度之间存在线性关系这 3个条件 ,对基准站的双差整周模糊度进行搜索。特点为快速、简单、实用 ,不受周跳影响 ,只需
An ambiguity searching method for Network RTK beselines between base stations at single epoch is proposed in this paper. The mathematic models, resolution process and results analyses are given in detail. The main idea of this method is composed by using carrier phase data of dual frequencies but not solving the corresponding observational equations, and using the linear relation between dual frequencies ambiguities and the known coordinates of base stations directly to search the double difference integer ambiguities by only one epoch. The main advantages of this method are fast, simple and useful, and this method avoids the effect of cycle slips, it only needs one epoch data to resolve the double difference integer ambiguities.
