The Accuracy Indicators Analysis of GPS and GLONASS Receivers

This article deals with the analysis of the accuracy of the receiving devices of the rangefinder signals of satellite global positioning systems. The structure of universal devices for analyzing the accuracy characteristics of navigation receivers based on averaging the received positional data both over time and over a set is considered. The results of GPS+GLONASS navigation based on the use of real measurements are given. All navigation measurement data were obtained using five combined GPS+GLONASS receivers Ublox-7, located at one point in space. All statistical processing of positional data streams from all GPS receivers included in the system is carried out by software and hardware of the IBM PC. Data input into the computer is realized based on the use of the GinZZU USB hub through a free USB port.The fundamental possibility of constructing high-quality receivers for satellite navigation signals based on the processing of a set of received signals from receivers of a low price category is analyzed.
