中文摘要：
针对高精度GPS基线向量网平差所涉及的理论技术问题，系统地论述了GPS基线向量网平差的流程，着重研究讨论了基线协方差、抗差估计、系统参数、基准模型等在GPS基线网平差中的应用，最后介绍了基于上述理论方法所编的高精度GPS基线向量网平差软件HPGPSADJ1．0，通过解算实例，与精密水准结果相比较，分析讨论软件解算精度。
英文摘要：
Based on the theoretical and technical questions of adjustment for high-precision GPS baseline network, this paper discusses systematically the steps of GPS baseline network adjustment. Applications of baseline covariance, robust estimation, system parameter and reference model etc in the adjustment are analyzed emphatically. Finally, the adjustment software HPGPSADJ1.0 for baseline vectors is introduced, comparing with high-precise leveling, resolving precision of this software is analyzed.
