说明：  《载波相位相对定位双差方程原理》验证 《载波相位相对定位单差方程原理》验证 《载波相位相对定位双差方程原理》验证 《载波相位相对定位双差方程原理》验证当基站离流动站很近，并假设流动站概略坐标等于基站坐标，那么双差方程中距离向量就为0(&quot Double difference carrier phase relative positioning equation theory&quot test &quot single-difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation principle&quot is verified when the base station from the mobile station near, and assuming that mobile station is equal to the base station coordinates approximate coordinates, so double-differential equation from the vector is 0)
