METHOD FOR LANDING OF AIRCRAFTS WITH APPLICATION OF SATELLITE NAVIGATION SYSTEM AND LANDING SYSTEM ON ITS BASIS Russian patent published in 2009 - IPC G01S13/91 

FIELD: radio engineering.

SUBSTANCE: current coordinates of aircraft (AC) are detected by orientation relative to several satellites with available coordinates, for this purpose satellite signals are received with the help of onboard receiver, board pseudodistances are defined through code measurements, simultaneously satellite signals are received on local control-correction station (LCCS) with available location using ground receiver, defining surface pseudodistances by means of code measurements, coordinates of specified glide path are translated on board of aircraft in common packet of information through data transmission line, and coordinates of specified glide path are received on board. Besides on LCCS and on board of AC, accordingly, for ground and onboard receivers, simultaneously with code measurements of ground and onboard pseudodistances, phase measurements of mentioned pseudodistances are carried out by detection of phase of satellite signals carrier frequency, phase correction is calculated for phase measurement of pseudodistance for each satellite with compensation of time scale deviation in ground and onboard receivers, then jumps of phase measurement of ground and onboard receivers are detected for each satellite, mentioned jumps of phase measurements are compensated, pseudodistances are corrected with account of compensation of jumps in phase measurements of pseudodistances, corrected values of ground and onboard pseudodistances are formed. Using corrected values of ground pseudodistances, they define corrected differential corrections, specified differential corrections are translated to AC board in common packet of information together with coordinates of specified glide path, and on board they receive specified differential corrections, using mentioned specified board pseudodistances and specified differential corrections, they calculate final pseudodistances, which are used to form deviations of specified coordinates of aircraft from specified glide path. Landing system is suggested, using suggested method.

EFFECT: higher accuracy of aircraft coordinates detection.
