METHOD FOR DETERMINATION OF CO-ORDINATES OF DISTANT OBJECT ON TERRAIN AND DEVICE FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: instrument engineering, in particular, remote meters of co-ordinates of objects on the terrain.

SUBSTANCE: the method consists in measurement of the object co-ordinates, observer's co-ordinates and transmission of them via communication channels for further use. The observer performs terrain scanning through a sighting device up to getting to the sighting line of the respective object with fixation at this moment of the indications of the vertical, azimuth, target elevation sensors, device for determination of the observer's own co-ordinates. The obtained data are transmitted to the control and computation devices. The point of location of the observer in the space of the digital terrain model is de4termined from the obtained own co-ordinates of the observer. The position of the sighting line above the digital terrain is restored from the other indications of the sensors. The distance to the object is determined as the distance of the point of location of the observer on the digital terrain to the point of intersection of the restored sighting line and the digital terrain. The device has location and orientation sensors, control and computation device, transceivers, sighting device, which is connected to the vertical, azimuth, target elevation sensors. The outputs of the vertical, azimuth, target elevation sensors and the output of the device for determination of the observer's own co-ordinates and connected to the inputs of the control and computation device. The control and computation device has a storage unit, which has a digital observation terrain model and is connected to the transceiver. The device for determination of the observer's own co-ordinates has a navigation equipment of its own.

EFFECT: enhanced reliability of operation and simplified design of the device for determination of co-ordinates, absence of factors disclosing the operator.
