顾及垂线偏差的对流层改正对精密单点定位解的影响

摘要

对卫星高度角计算的基准问题进行分析,研究测站点垂线偏差在GPS测量中对卫星高度角和对流层改正的影响,并分别进行精密单点定位解算,发现其对最终点位解的影响不应忽略.%The altitude angle of satellite is analyzed,and the influence of vertical deflections on altitude angle of satellite and tropospheric refraction corrections for GPS surverying is researched.The coordinates of stations are calculated using precise point positioning mode.The result shows that the influence of vertical deflection on station coordinate cannot be ignored.
