Abstract

The invention provides a data transmission system between noncontact double super satellite cabins and an operation method thereof. The integrated responder of a measurement and control subsystem supports measurement and control to the ground and measurement and control to the relay through different frequencies, and a load cabin and a platform cabin adopt the working mode of different pseudo-codes. The data integrated processor of a data transmission subsystem receives the high speed data of camera load, and the data are wirelessly transmitted to the platform cabin in real time to perform data transmission or the data are stored and arranged back to the platform cabin from a storage device and then data transmission is performed according to the situation of whether the satellite is within the border or the visual arc segment of the relay satellite. The inter-satellite communication responder adopts the modulation mode of an inter-satellite non-coherent direct sequence spread spectrum communication system and works in the S-band and the duplex mode, and the inter-satellite communication responder between the two cabins adopts the mode of different bands and different codes. The load cabin and the platform cabin communicate in a noncontact manner so that the problems of interference and fluttering caused by vibration of large flexible structures and moving parts can be solved, and the inter-satellite communication efficiency and the communication efficiency to the ground and the relay can be enhanced.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a non-contact double super-satellite inter-cabin data transmission system and an operating method thereof. Background technique [0002] Traditional satellites adopt a structure in which the load cabin is connected to the platform cabin and the load cabin is driven by the platform cabin, which is difficult to solve the interference and flutter problems caused by the large flexible structure and the vibration of moving parts. The master-slave non-contact double supersatellite platform breaks the traditional design idea of ​​fixed connection between the satellite load compartment and the platform compartment, and adopts a new design method of dynamic and static isolation non-contact, master-slave decoupling and high precision, which can fundamentally solve the problem of load pointing accuracy and stability A major problem that is difficult to significantly improve.
