Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0031] When the satellite is in orbit, the transponder loaded on the satellite platform, due to the use of a digital chip, will cause a single event function interruption to the interference of a single event, that is, the in-orbit communication function of the two transponders will fail at the same time. At this time, the ground The remote control command sent by the measurement and control system to the satellite cannot be received normally, and the satellite is out of control. The present inven...

Abstract

The invention provides a method and a system for recovering an on-orbit latch of a satellite-borne transponder. The method comprises the following steps that a ground station or a relay satellite sends a remote control uplink instruction or data injection to a satellite; whether the two transponders on the satellite are latched or not is judged, if no response exists on the satellite, the two transponders are latched at the same time, and a double-channel fault mode is entered; if a response exists on the satellite, the two transponders work normally, or one of the transponders A and B is latched, and a single-channel fault mode is entered under the condition that one transponder is latched; the fault responder B is restarted after power failure; the ground station or the relay satellitesends a remote control uplink instruction or data injection to the satellite by using the transponder channel restarted after power failure; and if the satellite normally receives the instruction or the data, the fact the transponder restarted after power failure recovers normal work is indicated. According to the invention, when the two transponders are latched, the satellite can automatically make a judgment, autonomous power-off restart is carried out on the latched transponders, and the measurement and control communication function is recovered.

Description

technical field [0001] The invention relates to a satellite measurement and control communication system, in particular to a recovery method and system for an on-orbit latch of a satellite-borne transponder. Background technique [0002] When the satellite is in orbit, two transponders are generally used to communicate with the ground measurement and control system. The two transponders serve as backups for each other, that is, when one transponder fails, the other transponder is used for normal communication. At present, with the development of digital technology, a large number of digital chips such as FPGA, DSP, PROM and other digital components are used in the design of the two answering machines. The weight of the machine is reduced to achieve the purpose of miniaturization and lightening. However, when the satellite is in orbit, these components are sensitive to space single events, especially the transponders loaded on the satellite platform. Due to the use of digita...
