Volume controllable inflatable antenna

Abstract

The invention relates to a volume controllable inflatable antenna which at least comprises a satellite thruster, at least one acquisition module and at least one adjusting module, wherein the first adjusting module is configured as that first antenna adjustment and control information is confirmed on the basis of orbital transfer environment monitoring information, estimated consumption of the satellite thruster in executing a specific event is confirmed, orbital transfer demand mixing ratio coefficients corresponding to the satellite thruster and the inflatable antenna, and a first control instruction and a second control instruction corresponding to the coefficients are confirmed on the basis of the first antenna adjustment and control information and the estimated consumption, then a first control instruction is received by the first adjusting module of the inflatable antenna in a mode that aerodynamic compensation is implemented to a second adjusting module of the satellite thruster for receiving a second control instruction, and on the basis of second aerodynamic information which is acquired by a second acquisition module at a second moment and is related to an area of an ignition orbital transfer position, at least one time of adjustment modification is implemented to execute at least one related specific event.

Description

technical field [0001] The invention relates to the technical field of aerospace technology, in particular to a volume-controllable inflatable antenna. Background technique [0002] The orbit of low-orbit satellites can quickly reach the predetermined orbit and start work because of its relatively low operating altitude. In addition, low-orbit satellites have a relatively short orbital period, and the time interval for passing the same point is less, and they are more frequent in reconnaissance than traditional satellites, so they can obtain more information. But at the same time, because the orbital height of low-orbit satellites is lower than that of traditional satellites, the aerodynamic force on low-orbit satellites is dozens of orders of magnitude higher than that of traditional satellites. The existence of the atmosphere has already had a non-negligible impact on the operation of spacecraft. Under the action, the spacecraft will decelerate faster, so it is necessary ...

[0007] Chinese patent (publication No. CN103928743B) discloses a loading and unfolding control mechanism of a rib-type air-inflatable unfolding parabolic antenna, which belongs to the technical field of rib-type air-inflating unfolding paraboloid antennas, and solves the problem that there is currently no effective The loading mechanism and the problem of being unable to effectively control its deployment process include a loading mechanism and a deployment control mechanism; the connecting parts of the loading mechanism are arranged below the fixed disk of the deployment control mechanism and are connected by bolts, and the loading mechanism The number of blades is the same as the number of support bars and rib pressing bars of the deployment control mechanism. The support bars are set corresponding to the gaps between the blades, and there are gaps on both sides of each blade.

However, in the orbit transfer optimization method provided by this patent, only a single power assist method using aerodynamic force is used, resulting in an extremely low utilization rate of aerodynamic force. the method of spacecraft control still suffers from low fuel savings and long transfer times
