摘要

GPS has been widely used in engineering surveying and deformation monitoring. Based on the comparison and analysis of the solutions of three types of representative on-line GPS data processing software,it is concluded that: (1) if 1hr data amount is used to generate the solution, the precision of coordinate generated by AUSPOS is cm level,while the precision of coordinate generated by SCOUT and CSRS-PPP is dm level; (2) if the data amount used to generate the solution is between 2 hr and 6 hr, the precision of coordinate generated by AUSPOS, SCOUT and CSRS-PPP is all up to cm level; (3) if the data amount is more than 6 hr, the precision of the solution generated by AUSPOS and SCOUT can be up to mm level, while the precision of coordinate generated by CSRS-PPP is still cm level. The result of this research has a value of reference in selecting proper on-line GPS data processing software and determining data collecting time in engineering surveying and deformation monitoring.
