The normal equation of GPS observation equations in short time observation are usually ill condition, the correlated study is performed. The method of restricted condition is used to eliminate the ill condition of the normal equation, and the LAMBDA method is used to fix the integer ambiguity. The corresponding experiments have been executed based on these techniques. The experiments results show that, for single frequency GPS receiver, the fixed ambiguity can be finished in 5 epochs and centimeter-level of positioning accuracy is achieved.
