Results of Experimental Studies of Positioning Accuracy Using Various Satellite Navigation Systems
There is a constantly growing interest in tasks involving groups of autonomous mobile objects: environmental monitoring, elimination of consequences of technological disasters. A navigation system of an autonomous mobile object and the accuracy of navigation data play a key role in tasks of autonomous control of mobile objects. These tasks include: route planning, control over driving parameters of an autonomous mobile object, arrangement of interaction within a group of autonomous mobile objects. The accuracy of navigation data from satellite navigation systems essentially depends on such factors as: the number of visible satellites for any available navigation system, receiver characteristics, terrain features, environment properties. It is an important task to make a rapid choice from the available satellite navigation systems or their combination that provides the most accurate position when differential corrections are not available. This paper covers the technique that allows quick choosing of the most precise satellite navigation system or their combination. The choice is based on a statistical analysis of data received from satellite navigation systems.
