Abstract:

Controls are useful in all survey works and how they are established must be treated with great caution. Recent increase in the use of Global Positioning System (GPS) as a way of fixing positions of survey beacons as compared to the traditional methods brings to mind how certain precautions about GPS must be adhered to so that GPS technique in position fix is used with the least problem. The commonly used GPS receivers in Ghana for most cadastral surveys are the single frequency GPS receiver. This paper investigate the use of Single frequency GPS for position fix by differential GPS technique. Ten controls on the University of Mines and Technology campus were coordinated by Precise Traversing and GPS techniques. Single frequency GPS receivers were employed to obtain the coordinates of the selected beacon at different epochs and orientations of the GPS receivers. The results shows average standard deviations for morning observations for the planimetric coordinates to be 0.007 and 0.0112 m for receivers oriented to the north and not to the north respectively. Afternoon and evening obtained coordinates gave 0.0132 and 0.012 m; and 0.0098 and 0.01136 m average standard deviations for orientations of the receivers to the north and not to the north direction respectively. From the analysis of the results obtained, the morning and evening observations with GPS receiver oriented to the north direction produced better accuracy.
