ASYNCHRONOUS DIFFERENTIAL-RANGE ALGORITHM FOR POSITIONING AN UNMANNED AERIAL VEHICLE IN THE ABSENCE OF GLOBAL SATELLITE NAVIGATION SYSTEM SIGNALS

Kopyltsov Vladimir Yuryevich  (Deputy General Designer, Head of Department, Special Technology Center, St. Petersburg)

The paper considers the problem of positioning a UAV performing a target task in conditions of GNSS signal suppression. The source of the navigation signal, which is a sequence of pulses, is a navigation object (UAV), which transmits this signal to reference points for estimating the pulse arrival time and then determining the coordinates of the navigation object. As a positioning method, an asynchronous differential-range method is analyzed, the essence of which is to find the differences in the pulse arrival time between N reference points and their shifted, for the pulse repetition interval, copies. Modeling has shown the efficiency of the proposed approach for determining the coordinates of the UAV.

Keywords:local navigation systems, asynchronous total-range method, radiotechnical control, determination of UAV coordinates
