TOTAL-RANGE-MEASURING MODEL OF POSITIONING A RADIO-TECHNICAL CONTROL COMPLEX BASED ON UNMANNED AERIAL VEHICLES

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

The paper considers the problem of ensuring navigation of a radio-technical control complex based on unmanned aerial vehicles (UAVs) using a total-range-measuring local navigation system. A combined positioning algorithm has been developed that does not require synchronization of reference transceiver points. The metric of calculating the lower bound of Cramer-Rao is proposed as an assessment of the quality of this algorithm. It has been established that the accuracy of determining the coordinates of the UAV using the proposed local positioning model depends on the number and spatial arrangement of reference transceiver points, as well as on the accuracy of determining the moments of time of receiving navigation signals. Computer modeling of the proposed algorithm has been carried out, which confirmed the operability and required accuracy of the developed LNS.

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