Assessment of the mobile positioning accuracy in cellular networks

The paper considers the prospects of using existing cellular communication networks to create an integrated communication, navigation and surveillance system (iCNS). The main attention is paid to the problem of using iCNS to solve a navigation problem. Classical methods for solving the problem of positioning unmanned aircraft are considered, for which expressions are given that allow estimating the accuracy of positioning. The methods unique to cellular communication networks and their main features are also considered. A methodology for conducting field experiments to assess the accuracy of positioning of a subscriber terminal is presented, and the results obtained for a city of regional subordinance are compared to the results of an experiment in a large city. The prospects of using existing cellular communication networks to solve CNS problems have been determined.
