Influence of observation mode and number of GPS receivers in accuracy of calculating coordinates of points


Abstract in English

GPS technology considers the essential tool for establishing geodetic networks. Static method of GPS is used often in observing geodetic network points. Establishing geodetic networks using GPS requires accuracy, consistency and economency. This paper discusses influence of observation mode and number of GPS receivers in accuracy of calculating of coordinates of points. Coordinates of network points are clculated using tow and three GPS receivers and with diferent methods like radial, traverse, network. Comparison between coordinates for network points obtained by several cases is performed. The differences between coordinates indicate accuracy of network method in calculating coordinates when three or more receivers are avlible. When tow receivers are avilable the radial method is the best in accuracy and consistency.
