Abstract. The paper presents algorithms for integrated processing of navigation data to determine the position of an object. A particle filter–based algorithm has been developed and tested using real flight data from a helicopter equipped with a standard onboard avionics suite. The feasibility of position correction using information from a digital elevation model (DEM) has been demonstrated. A comparative assessment of coordinate accuracy was conducted using data from various sources.
