Abstract:
Scientists and researchers have always been inspired to identify the three-dimensional coordinates of satellite communication. The critical aspect that highly accurate requires is the use of the Global Navigation Satellite Systems (GNSS) in static or semi-static mode. However, it was necessary to study ways of improving the accuracy use of such systems in a dynamic environment, which is of great significance for several applications, because of the substantial improvement of the abilities of satellites and the signaling structure. The objective of this research is to analyze and improve the accuracy of the point positioning technique. The model of the essential positioning point was evaluated. It was proposed to establish a technique of kinematic point positioning. The suggested procedure was tested. A study was carried out. The raw data was extracted from real rover data and simulated databases observed. In order to produce simulated base data, the final products of the International Global Navigation Satellite Network Service (IGS) were used. The results show that using simulated base data, horizontal and vertical accuracy can be increased by 75 % and 72 %, respectively. The Chi-square test is used to evaluate the alternative solution improvement for various cases. The Chi- square test states that two base stations are more accessible to be used during evaluation than one base station.
