Improve determining the location of a moving body on map by low cost GPS receiver
Student Conference on Research and Development - Trang 242-244
Tóm tắt
The ability to determine the accurate global positioning of a vehicle has many useful commercial and military applications. We study the way of using a low cost GPS receiver for determining position and propose an algorithm for vehicle navigation on a map. First we measure the parameters of the fixed position, such as dilution of precision (DOP) and signal to noise ratio (SNR). Then the parameters feed in to a fuzzy system. The output fuzzy system is reliable factor. We can select the more accurate position fixes according to the values of reliable factors. The position fixes are used provide the digital map. The stages of algorithm implementation are stated. Real road experiments demonstrate the effectiveness and applicability of the proposed algorithm and the developed car navigation system.
