experiment example

[0121] The flight trajectory of the aircraft is simulated by the aircraft simulation system. In the simulation experiment, three aircraft of the same type are launched to the same target position at the same launch site. For each aircraft, the target point is within the range. The distance between the target point and the launch point is 20,000 meters, the speed of the aircraft is controlled at 6-10 rpm during the travel process, and the overload on each aircraft is above 10,000g, and the flight trajectory of each aircraft is mapped. And then get image 3 ;

[0122] During the simulation process, the position and speed information of the aircraft is calculated by computer simulation in real time, and converted into satellite signals, which are sent to the control system of the aircraft in the form of satellite signals. Suspend the transmission of the satellite signal, or reduce the number of satellites of the satellite signal to make it a lost satellite signal.

Abstract

The invention discloses a satellite signal fitting reconstruction system and method applied to a high-dynamic aircraft. According to the system, the receiving capability of satellite signals is improved through a sheet-shaped antenna and the possibility of satellite loss under high dynamic is reduced; with multiple receivers, stable and reliable satellite signals are provided for the aircraft to the greatest extent. Furthermore, when the satellite losing is determined, satellite signals are self-fitted and reconstructed, the position and speed information of the aircraft required for calculating the required overload is provided for the microprocessor module, so that the stability of the aircraft is maintained in the satellite loss period; and when the satellite is not lost, the satellitesignal with the largest number of satellites is selected to calculate the position and speed information of the aircraft, the required overload is calculated, so that the aircraft is controlled.

Description

technical field [0001] The invention relates to a system and a method for coping with an aircraft when a satellite is lost, in particular to a satellite signal fitting and reconstruction system and method applied to a high dynamic aircraft. Background technique [0002] Star loss is the most common problem encountered by satellite-guided aircraft during flight, especially for high-dynamic aircraft. The problem of star loss is even more serious. This type of high-dynamic aircraft has the following disadvantages during flight: [0003] (1) Poor autonomy and susceptible to interference, including various signal interference, regional factor interference, etc.; [0004] (2) Susceptible to weather conditions, especially in harsh environments, may cause the satellite receiver on the aircraft to fail to receive satellite signals; [0005] (3) Its own high dynamic characteristics will also affect the reception of satellite signals; [0006] (4) When the star is lost, the high dyna...
