The Modification of Tropospheric Correction Bias in Vertical Direction in Network RTK
Abstract We propose a new method which modifies users’ tropospheric corrections based on the height information of stations and users. We use data from six CORS stations in America and seven stations in the SatRef network in Hong Kong to analyze our method. Results show the method can modify tropospheric correction bias in vertical directions effectively, that the method performs well while the elevation difference is above 100 m, bringing the precision of tropospheric correction to the cm level.
Key words :
network RTK
troposphere correction
height
bias correct
