MODE OF CONTROLLING WORKING CAPACITY OF AIRBORNE RECEIVER INDICATOR OF SATELLITE RADIO NAVIGATIONAL SYSTEM Russian patent published in 2005 - IPC

FIELD: the proposed invention refers to radio navigation namely to modes of controlling working capacity of a receiver indicator (RI) of a satellite radio navigational system installed on the board of a flying vehicle.

SUBSTANCE: the mode is that the altitude H_RA of the flight of a flying vehicle is measured with the help of installed on it a radio altimeter (RA), the altitude h_r of an area above which a flying vehicle flies at the moment of the altitude measuring using for this purpose data about planned coordinates from the output of the receiver indicator of the satellite radio navigational system and digital map of an area, an absolute altitude H_a= H_RA +_{hr, is calculated and compared with the altitude HRI, taking from the output of the receiver indicator and a signal of its working capacity is formed if |Ha- HRI| is smaller than the installed threshold Th.}

EFFECT: using of the proposed mode allows in comparison with known modes to decrease the magnitude of the threshold Th. and buy this increase the reliability of RI control installed on a flying vehicle.
