EVALUATION OF THE LOW-COST SINGLE FREQUENCY GPS RECEIVERS' ACCURACY IN CASE OF KINEMATIC AND STATIC RELATIVE POSITIONING
SINOPSIS
The objective of the work carried out in this paper is to evaluate the accuracy of the low-coast GPS receivers in the case of relative positioning for static and kinematic mode. The evaluation was applied on a navigation receiver implemented on a Smartphone. The collected raw data was processed by two software packages; TBC and RTKLIB in addition to our developed MATLAB program. In static mode the observation zones are chosen according to their distance from the reference station (5, 10, 20, 30, and 50 Km) to study the behavior of the precision according to the baseline. It can be seen from the results obtained in this mode compared with these obtained by the Trimble NetR9 that the planimetry position error is a few decimeters and the altimetry position error does not exceed two meters fifty. For the kinematic mode, the observation is done with the Trimble R10 and the navigation receiver embedded in a car in a road of about twenty Km length. Under favorable observing conditions, the position error in this mode is about two meters.
