METHOD OF CONTROLLING DATA FROM SATELLITE NAVIGATION SYSTEMS AND DEVICE THEREFOR Russian patent published in 2016 - IPC G01S19/08 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and specifically to satellite navigation systems (SNS), and can be used for determining integrity of data from SNS. Control of output parameters of SNS is carried out on two levels, at first level "rough control" determines latitude, longitude and altitude with given accuracy, wherein thresholds on coordinates are defined proceeding from area limited by maximum possible range and flight altitude and speed thresholds is controlled by speed module, which shall be within operating range. At second level control over sliding observation interval is carried out, where control over speed measurement is performed and calculation of variation of magnitude of velocity, as well as control of coordinates measuring and calculation of variation of increment of track. In case of exceeding of velocity variation magnitude or path increment variation specified threshold value malfunction symptom is formed Pr=1. Control output of same values of parameters of SNS is performed till "n" matches, when SNS malfunction symptom Pr = 1 is formed. Proposed device comprises receivers of satellite signals of SNS, inertial navigation system, coordinates of first level control unit, control unit of parameters of first level, four switches, coordinate increments of second level control unit, control unit variation magnitude of velocity of second level and correction unit. Said result is achieved by fact that method involves measurement of data coming from navigation satellites, location and speeds of consumer, compared with tolerable threshold values directly output parameters of SNS.

EFFECT: technical result is increase of reliability of integrity of information directly on consumer facility.
