摘要：
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 based 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 derived from BDS is better than 1 mm for the horizontal components, better than 2 mm for the vertical components, which is still a little lower than GPS. © 2016, Surveying and Mapping Press.
