Webremoved by a technique known as differential GPS (dGPS). dGPS involves placing a stationary GPS receiver at a known position and measuring the supposed range to each satellite. Corrections are then calculated and used by receivers in the nearby area. dGPS can give sub-metre accuracy, but is limited by distance from the reference receiver. WebDGPS are summarized in figure 1.1. Figure 1.1: Benefits of INS/DGPS Integration [Skaloud, 1999]. The overall performance of the direct orientation method is limited primarily by the …
