METHOD FOR FINDING ONE'S BEARINGS ON THE GROUND AND DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: applicable in instrument engineering, in particular, in instruments using remote control of the actions of the observer-operator on the ground.

SUBSTANCE: the method consists in measurement of the object coordinates, observer's coordinates and transmission of them for further use, as well as in finding of the observer's bearings with due account of obtaining of target designation and determination of the error of the preset and current coordinates. The observer performs scanning of the ground with fixation of the readings of the azimuth and elevation angle sensors, readings of the device for determination of the observer's own coordinates at detection by it of the object of observation. These data are transmitted to an individual control device of the observer. The own coordinates of each observer via individual transceivers are transmitted to the control and computations device of a group equipment, having a storage unit, which contains a digital model of the ground relief of observation and a data base for target distribution and renewal. The obtained data on location of the observers, as well as of the targets from the data base for target distribution are applied to the relief digital model. The data on the relative location of the observer and the target distributed to him are transmitted via the transceivers to the observer's control device, in which they are compared with the data obtained from the azimuth and elevation is transmitted to the indicators of the vertical and horizontal turning of the observer's scanning device. The device for finding one's bearings on the ground has location and orientation sensors, control and computations device, transceivers, scanning device for the observer with indicators of vertical and horizontal turning, sensors of the location in space in azimuth and angle of elevation, device for determination of the observer's own coordinates, having a navigational equipment linked with a satellite. The observer's transceiver is coupled to a group transceiving device connected to the control and computations device of the group equipment. The control and computations device of the group equipment comprises a storage unit, having a ground relief digital model and a data base for target distribution.

EFFECT: simplified and enhanced reliability of use of the system of transmission to the operator of the information on the direction on the ground.
