Research on the Real Time Formation of Optional Equivalent GPS Observations in GPS Fiducial Stations

To make full use of GPS fiducial stations and to adapt them to multipurpose applicaitons such as geodesy, WADGPS, geodynamics and etc., with the aim of resolving the basic problem regarding the adaptability of GPS fiducial stations, this paper employs an orthogonal fitting approach to forming equivalent observations in real time with optional sample rates. Practical tests show that the algorithm is steady and ideal.
