Method for positioning aircraft based on 1090ES data chain ground stations

Abstract

The invention discloses a method for positioning an aircraft based on 1090ES data chain ground stations. The method for positioning the aircraft based on the1090ES data chain ground stations comprises the following steps that firstly, the four 1090ES data chain ground stations are selected and respectively receive air position information sent by the aircraft, timestamps are added to the air position information, and the air position information is transmitted to a monitoring terminal; secondly, the monitoring terminal receives the air position information, containing the timestamps, transmitted by the four ground stations and uses one 1090ES data chain ground station as the central station, the remaining three 1090ES data chain ground stations are used as peripheral stations, the monitoring terminal conducts time difference processing on the same air position information, at the same second, of the same aircraft, the intersection point of three unilateral hyperboloids is worked out through three time difference equations, and then the target position is determined. The method for positioning the aircraft based on the 1090ES data chain ground stations does not depend on S-mode intermittent broadcast position information, can be used for position information accuracy verification and can also be used as a standby monitoring means.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an air traffic control monitoring technology for ensuring aircraft flight safety. Background technique [0002] The 1090ES data link system intermittently broadcasts information such as aircraft identification code, position, altitude, speed, direction and climb rate through the S mode, and the ground station receives the information and displays it on the pseudo-radar display. The monitoring and management of aircraft by the 1090ES data link ground station depends on the intermittent broadcast of the airborne Mode S transponder. If the position information source of the S mode transponder is invalid or wrong, the 1090ES data link ground station will receive and transmit the invalid and wrong aircraft Location information seriously affects the control effect. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention...
