Single point positioning using low cost single frequency GPS receiver

Since the Selective Availability (SA) was set to zero, the point positioning becomes an interesting field of study. This study was to develop the single point position solution with accuracy better than 2 m using a low cost single frequency GPS receiver. The positioning algorithm was written in Matl...
