A method for reconfiguring on-orbit functions of satellite processing payloads

Abstract

The present invention discloses a method for reconstructing an in-orbit function of satellite processing type loads, including the steps as follows: a data transmission is processed between a ground terminal and a satellite terminal; the data reconstruction transmission and a data inputting are processed among satellite system equipment / parts; and the ground terminal real-time controls and monitors the data reconstruction loading control and state through remote control and remote metering information. The method can support an out-of-order transmission and a breakpoint resumption of single satellite and more satellites at the same time so as to efficiently ensure an integrity and validity of the data; and simultaneously, the method supports the data transmission control among equipment and parts of the equipment, and realizes the reconstructing data loading, state monitoring and exception handling by utilizing an existing measurement and control data transmission channel and a protocol of satellite processing equipment.

Description

Technical field [0001] The invention relates to a method for reconstructing on-orbit functions of satellite processing loads, which can be widely used in the design and realization of on-orbit functional reconstruction of various satellite processing loads, and belongs to the technical field of satellite communication system design. Background technique [0002] For satellite communication systems, having the ability to reconfigure the system's on-orbit functions, on the one hand, can change the original functions of the system through on-orbit reconfiguration, so that the system has new capabilities and responds to changes in market and user application requirements in a timely manner; on the other hand, In view of the defects and deficiencies in design and implementation, the system can be continuously improved and perfected, so that the system has the ability to repair and improve on track.

AI Technical Summary

Problems solved by technology

[0003] Traditional functional reconfiguration methods pay less attention to system-level functional reconfiguration, and often only target specific devices / components; reconfigured file data is transmitted through a dedicated satellite-to-earth transmission channel, and the transmission process is mostly controlled by an improved ARQ protocol. Star route forwarding does not support out-of-order transmission and breakpoint resume transmission; the designed function reconstruction method generally requires a dedicated reconstruction control device, and the on-star processing only involves reconstruction data transmission between devices in the device, and is not designed for general use Reconfigured data transmission control protocol between specific devices / components; reconfigured data loading and status monitoring are generally realized through a dedicated transmission channel combined with a custom protocol
