METHODS FOR DETERMINING MOBILE LOCATION IN ZONES WITHOUT GPS RECEPTION

P. M. Porvatov, S. M. Elsakov

Abstract


The paper is devoted to methods of determination of mobile device location in zones where GPS signal does not get, using only sensors of the mobile device. Most mobile devices are completed only with GPS sensors and accelerometers. Less often mobile devices are completed with a gyroscope, a magnetic compass. The problem is to choose the best method of determination of mobile device location using only sensors of device. In reality it is not possible to use only accelerometer, gyroscope and magnetic compass, because it is necessary to calculate an object location from the already known point. The known point can be received from GPS or from points of the wireless Internet.


Keywords


location determination methods, inertial navigation, comparison of methods of location determination, determination of location in zones of GPS lack, notation of a way in the enclosed space, the accelerometer, longitude, latitude.
