Abstract :
In this paper, the kinematic GPS positioning method for dual frequency (L1 and L2 bands) observations is presented by applying the Kalman filter. And the method is examined by using real receiver data. As a result, if the baseline length is short, the method can resolve the integer ambiguity much faster than using only single frequency data. The method could also instantaneously (epoch by epoch) resolve the ambiguity for 94.8% of 1000 epoch data.
