中文摘要	The differencing, technique is useful in global positioning system (GPS) positioning when two or more GPS receivers collect simultaneous observables from common satellites at each epoch, and all carrier-phase observables have the same normal distribution. An analytical probability distribution of the single-, double-, triple-, and multi-difference GPS observables is obtained. This analytical model. called ISO2002, has a good matrix structure, in which I indicates the number of receivers, S indicates the number of observed satellites, and O indicates the number of epochs. The variance-covariance matrix can be expressed as the Kronecker product Of several small matrices. so its inverse is equal to the Kronecker product of the inverses of those sub-matrices. Moreover. the small matrices are circulant or symmetric diagonal Toeplitz matrices. so their inverses have analytical solutions. The analytical model ISO2002 proposed to compute the inverse variance-covariance matrix is shown to be very effective.
