  • 摘要:

    This paper is a result of the work done by the authors in the field of movement evaluation at low speed in the atmosphere and low costs of the movement execution. Theoretical and constructive solutions are offered for telemetry of the following features of movement: instant and average speed movement sense and direction, instant position related to a fixed referential. The presented solution, the Doppler radio telemetry system with active fixed referential-described in the paper-was practically realized and experimentally its utility has been demonstrated.
