Abstract
In this paper, a GPS positioning algorithm using the H/sub infin// filter is presented. The algorithm is derived by combining the H/sub infin// filter with the LAMBDA (least squares ambiguity decorrelation adjustment) method which can efficiently solve an integer least squares problem. In the H/sub infin// filtering, the filter performance strongly depends on the design parameter /spl gamma/, so that the choice of the value of /spl gamma/ is very important. After briefly reviewing the H/sub infin// filter, we also propose a simple algorithm that gives adequate value of /spl gamma/. Finally, the proposed algorithm is examined by using the real receiver data which were obtained at two static points.
