研究了北斗卫星导航系统（BeiDou Ncivigation Safellte System，BDS）毫米级精度变形监测算法。首先改进了TurboEdit方法，以能够探测到1周的小周跳；针对BDS星座结构给出更为高效的独立双差观测值搜索方法；对于模糊度固定，采用决策函数和序贯模糊度固定相结合的方法。在此基础上，研制了BDS变形监测软件。最后，利用变形监测试验平台的实测数据，从星座分布、解算精度等方面分析了BDS在变形监测中应用的可行性。结果表明，目前在试验区域内BDS与GPS在卫星几何分布等方面基本相当。BDS的短基线解算精度略低于GPS，但仍可达到平面1mm以内、高程2mm以内的精度水平。...

| Notes | BeiDou Navigation Satellite System; deformation monitoring; software achievement;precision analysis 11-2089/P The deformation monitoring algorithm with millimeter level precision based on BeiDou Navigation Satellite System （BDS） was researched. The TurboEdit method was improved to detect small cycle slips, e.g. 1 cycle. Focusing on BDS constellation, a more efficient algorithm used to construct double-differenced observations was developed. The Bootstrap＋Decision function method was utilized to improve the probability of biases fixing. Based on the improved algorithm above, a deformation monitoring software bused on BDS was achieved. Afterwards, the availability of BDS in the field of deformation monitoring was analyzed in terms of satellites distribution and precision and accuracy of solutions, utilizing the observations acquired from the experimental platform. The conclusion was drawn that currently BDS is similar to GPS in terms of satellites distribution in the test area. The precision of short baselines de |
