Criteria Analysis of GPS Observational Data Quality
摘要
Abstract
It is important to evaluate the GPS observing data. The threshold values in current evaluating grade models have no criterion which influence the objectiveness of the observing data' s evaluation. In this paper statistical analyses have been carried out on main quality elements with 2000 stations' GPS observational data from CMONOC in 2011 and the related mathematical precision distribution rule has been found out. Consequently using the mathematical model of normal distribution the grade evaluation criteria indices have been determined. In the end the criteria indices have proved rational by evaluating GPS products quality observed in GPS integrated standardization site.关键词
