A new method for GPS fast ambiguity resolution
Ji Sheng · Journal of the China Railway Society · 2000
A new method for GPS fast ambiguity resolution is proposed, which has following advantages:(1)if current observation data is not enough to determine the integer ambiguity,more observations are needed to re initialize,the new method does not require to renew the calculation with all data,only needs supplement the changes of sum of squares of residuals due to new data added,so it shortens the calculating time,saves computer memory;(2)the new method ,searching on integer ambiguity,uses the integer Gauss transformation and constructs extremum conditions to accelerate the searching speed. Experiments shows that the newly developed method has faster solving speed and more efficient than the existing methods.
