Model analysis of baseline processing for high-precision GPS network

GPS baseline processing is an important step for GPS data processing.To research the model and method of high-precision GPS network baseline processing is full of significance on practical application.The author principally studies the model and method of GPS baseline processing for high-precision GPS network and analysed the key problems of baseline processing,Such as selecting reference frame and ephemeris,feference stration's coordinate,restriction Condition and the Parameters of the model.Combining with an example,the author processes the GPS data using GAMIT software and analyses the result.It analyses the key problem of baseline processing,such as selecting reference frame and ephemeris,reference station's coordinate,restriction condition and the paranaeters of the model.
