摘　　要：通过对国内外部分观测量较多的卫星激光测距站夜间和白天观测资料的统计,分析了激光测距回波探测成功率实际值和理论分析的差别,探讨了影响夜间、白天激光测距探测率的各种因素,为进一步提高数据探测成功率提供了实践依据。本文还介绍了近几年兴起的高重复频率卫星测距的方法,应用此测距方法可以获得更多的观测数据,有效地提高标准点精度。According to the statistics of the number of the returns in night and daytime of a few SLS stations national and international,the paper analyzes the difference between actual detection probability and theoretical probability.It also discusses various factors that affect the successful detection probability of the returns in night and daytime.These works provide practical reference for further improving data detecting probability.In addition,the paper introduces a new SLR technology at a high repetition rate.With this technology,data quantity will have an impressing promotion and the precision of the normal point will be improved evidently.
