随着差分GPS技术的发展,其应用于工程测量也越来越及,但随着基线长度的增加,常规差分GPS定位精度亦随之降低。为此,本文研究了基于虚拟参考站(Virtual Reference Station,VRS)的差分GPS定位算法,它能有效克服常规差分GPS存在的缺陷,使移动测量用户可在较大空间范围内获得均匀、高精度和可靠的定位结果。 更多还原

【Abstract】 VRS has been very common to be used in engineering survey with the development of difference GPS(DGPS).However,with the increasing of baseline length,the precision of routine DGPS will be decreased.In this paper,we research the algorithm of DGPS based on the virtual reference station(VRS),which can avoid the defect brought by the routine DGPS and make mobile measuring user to get an average and reliable precision in a large zone. 更多还原
