摘要
目前全球激光测距网日臻完善!国内的激光测距网也已初具规模,上海、武汉、长春等的SLR站已投入了正常观测。本文利用两批武汉站的1985年激光测LAGEOS卫星的资料,与同期的全球SLR网的资料一起,应用动力法[1],精密测定了武汉站的地心坐标。在归算中为了减弱地球自转参数的误差和力学模型的不确定性对测定测站坐标的影响,我们设计了多级复弧法,在不同弧段长度内联合解算地球自转参数、卫星轨道和武汉站的坐标,测得的武汉站地心坐标:高度h=38.871m±0.053m经度λ=114°.3462470±1°.2×10-6纬度φ=30°.5418007±1°.
By operating the second-generation satellite laser ranging system at Wuhan satellite tracking station, 10 passes and 575 ranging points for LAGEOS were obtained from July 1985 to Sept. 1985. Incorporating these observational data with those obtained frotn laser ranging to LAGEOS at 16 satellite tracking stations all over the world during this interval. the geocentric coordinates of wuhan Station in the SSC (SHA) system have been determined accurately by dynamic method and multistage-multiarc method with 7 ares of 42 days. The mean geocentric coordinates are:
H = 38.871m (±0.053m)
λ=114°.3462470 (±1°.2×10-6)
φ= 30±.5418007 (±1.1×10-6)
