Assessing the Accuracy of Navigation Algorithms Using a Combined System of GPS Satellites and Pseudolites

摘要

The purpose of this work is to assess thernaccuracy of different navigation algorithmsrnutilized for a combined system of GPS satellitesrnand pseudolites. The algorithms underrninvestigation are the ordinary pseudorange leastrnsquare algorithm (LSA), single difference andrndouble difference Kalman based algorithms, andrnthe newly derived algorithm which employs thernDoppler measurements. An integrity measure ofrnthe combined system for the differentrnalgorithms is also provided along with thernnavigation accuracy. A list of pros and cons forrndifferent algorithms follows the last section ofrnthe paper.
