Problems solved by technology
Therefore, new problems will be brought about. For example, the aircraft onboard navigation system drift accumulates for a long time, which may lead to excessive accumulation of navigation drift and affect the flight.
Furthermore, there may also be a problem of satellite positioning occlusion: there is a pylon connected to the aircraft and the aerostat, and power supply equipment and control equipment are placed on the pylon to facilitate the control of the aircraft. However, the pylon is located above the aircraft. And the volume is usually relatively large, so it may have an occlusion effect on the satellite positioning effect of the aircraft, so that the satellite receiving equipment onboard the vertically hoisted aircraft is prone to "receiving less satellites", that is, it can only receive signals from a small number of satellites. location data for
For example, due to the vertical hoisting of the aircraft, the satellite navigation receiving antenna located on the back of the aircraft can only receive less than half of the satellites under horizontal conditions, which affects the navigation accuracy

The invention discloses a near space vertical launching system. The system comprises a navigation auxiliary mechanism, a fixed connection support, a fixed connection control mechanism and a satellite signal receiving mechanism arranged on the fixed connection support. A temporary fixed connection mechanism is arranged in the fixed connection support; according to the near space vertical launching system provided by the invention, the connection between the aircraft and the fixed connection bracket can be temporarily changed into fixed connection (rigid connection) from flexible connection through the temporary fixed connection mechanism,so that satellite attitude determination data is transmitted through the navigation auxiliary mechanism mounted on the fixed connection support; and aircraft launching navigation enhancement before near launching is realized.
Description
technical field [0001] The present application relates to the technical field of aircraft launch, in particular to a system for launching vertically in near space. Background technique [0002] A flight vehicle is a device that flies in the atmosphere or in the space outside the atmosphere (space). The aircraft is launched into the air by the static buoyancy of the air or the aerodynamic force generated by the relative motion of the air. [0003] The traditional way of launching aircraft mainly includes rocket-assisted launching and aircraft-mounted aerostat-mounted launch. However, each has some defects. There will be extremely strong constraints, and when the aircraft is mounted, the airflow of the external storage will also cause severe interference to the aircraft platform. In this context, aerostat mount launch came into being. The aerostat-mounted launch is to mount the flight gas through the aerostat and launch the aircraft vertically in the adjacent space. In act...
