20 dgps: how it works dgps: how it works differential gps (dgps) is a technique used to improve the accuracy of the global positioning system. Dgps reduces the effects of ionospheric variations and can improve position accuracy typically to 1-5 meters. The dgps beacon transmitter is placed at a know...

21 sources of error using a dgps beacon receiver with your existing gps receiver can provide substantial improvements in accuracy; however, there may be occasions when the best possible accuracy will not occur. Several factors can contribute to a degraded dgps accuracy. Loss of dgps beacon signal — ...
