Abstract

The present invention discloses a multi-mode satellite navigation-based parafoil flight path control system, which comprises a comprehensive solution module arranged on a parafoil, a multi-mode positioning module and a path planning module. The multi-mode positioning module and the path planning module are connected with the comprehensive solution module. The path planning module is also connected with a flight control tracking module. The system further comprises a meteorological testing module and a landform data acquisition module, wherein the meteorological testing module and the landform data acquisition module are arranged at an air-drop place. According to the technical scheme of the invention, the navigation reliability and the navigation precision are improved. At the same time, the blind-action problem during the conventional parafoil flight path control process can be solved. Therefore, the achievable rate of the landing precision is improved.

Description

technical field [0001] The invention relates to the field of parafoil control, in particular to a parafoil flight track control system using multi-mode satellite navigation. Background technique [0002] In the remote control airdrop system, firstly, the position, altitude, speed and other information of the airdrop system in the air are obtained through the navigation module. The track completes the flight. [0003] In the prior art, the parafoil flight track controller adopts a single GPS satellite positioning and navigation, and obtains navigation information by receiving GPS satellite signals for positioning calculation. A single GPS navigation control system can normally perform navigation and positioning functions under good conditions of use, such as open areas, no occlusion, stable system working conditions and no interference. However, due to the limitation of a single navigation system, when used in special environments such as limited use in local areas and exte...
