Description
Technical Field
The invention belongs to the technical field of satellite net-capture waste satellites, and relates to a net-capture load emission window selection method based on the nutation characteristic of the attitude of a waste satellite.
Background
The method for cleaning the track environment is safe and effective by capturing the abandoned satellites by using the net-capture load and dragging the abandoned satellites to the track of the grave. In-orbit attitude of a satellite rejected will generally rotate about its axis of maximum inertia and will nutate with varying degrees of attitude and the nutation angle will be periodic, with a maximum nutation angle and a minimum nutation angle. The attitude nutation of the abandoned satellite makes the large-size accessories of the body, such as the tail end position of the solar sailboard, change constantly in space.
According to published data, the current net capture load adopts a direct transmission mode, namely, after the net capture load carried by a satellite approaches to a waste satellite to reach a proper distance, the net capture load is directly transmitted to capture a target, and the problem of transmission window selection is not considered. The direct launching mode can realize reliable capture for the abandoned satellite with stable posture or small posture nutation, but when the posture nutation of the abandoned satellite is large, the nutation of the abandoned satellite can lead the net body to contact the tail end of the large-size accessory of the abandoned satellite body in advance for a period of time during capture, and the net body is wound due to nutation motion, so that the net body configuration is disordered, and the net capture fails. And in addition, due to engineering constraints, the size of the net capture load cannot be infinite, so that the net capture load adopting a direct transmission mode inevitably has a certain nutation angle capture adaptive range, and the direct transmission mode aiming at the abandoned satellite with a large attitude nutation cannot realize capture. Therefore, the emission window needs to be selected according to parameters such as the attitude nutation rule of the abandoned satellite, the nutation angle adaptive capacity of the net-caught load, the time width from the emission moment to the capture of the net-caught load and the like, and the problem that the reliable capture of the abandoned satellite with large attitude nutation cannot be realized due to the direct emission of the net-caught load is solved.
