Annihilation method for gps integer ambiguity with residual probability scoring

摘要: A method of locating a first GPS receiver relative to second receiver. The includes the steps of: providing and receiver, spaced apart by distance D along baseline; receiving finite number observables from plurality satellites in period time; performing batch mode following series calculations on observables: calculating least squares estimate position for each receiver; single difference residuals; double an geometry free solution; applying geometric annihilation solution provide measurement D. processing differential apparatus is also described.
