Probabilistic properties of GNSS integer ambiguity
Yang Xiao-yun · Journal of Liaoning Technical University · 2007
In order to describe the reliability of GNSS positioning result and probability distribution of ambiguity,successful rate of solving ambiguity with various methods are deduced based on theories and practice and the TCAR/MCAR method used in the GPS and Galileo which have multifold frequencies after their being modernized in future are analyzed.It is indicated that LAMBDA algorithm can be used to dramatically improve successful rate of solving ambiguity and TCAR/MCAR method is just a special form of LAMBDA under multi-frequency.With the view of probability theory,the solution of integer ambiguity can be newly treated.The research result is also useful to improve the reliability of GNSS positioning result in practice.
