Task control packet generating method and executing method for satellite-borne relay user terminal system

Abstract

The invention provides a task control packet generating method and executing method for a satellite-borne relay user terminal system. The task control packet generating method comprises the following steps: planning a task control packet valid data area according to a bus communication protocol data packet format of a given satellite; classifying parameters into first type parameters and second type parameters, and encapsulating the first type parameters and the second type parameters respectively to form a relay user terminal working packet and a parameter correction packet; and completing task execution of a relay user terminal once with the relay user terminal parameter correction packet in cooperation with the relay user terminal working packet, and completing a task once only by the relay user terminal working packet if the relay user terminal parameter correction packet does not need to be changed. Through adoption of the task control packet design scheme, the packet storing capability of the satellite-borne relay user terminal system is enhanced greatly, and the use efficiency of the satellite is increased. Moreover, a soft interface of a satellite-ground operation room is standardized. The task control packet generating method and executing method have guiding significance to transplanting of the relay user terminal system to various satellite platforms.

Description

technical field [0001] The invention relates to a satellite-borne relay user terminal system, in particular to a method for generating a task control packet of the relay user terminal system and task execution. Background technique [0002] The space-borne relay user terminal system enables a satellite to have both ground-based and space-based transmission capabilities, and solves the timeliness of existing low-orbit satellite data transmission due to the limitations of on-board storage device capacity and ground receiving arcs. The status quo of poor reliability and availability, and provides a channel for timely discovery and rescue once a satellite fails. At present, the application of domestic satellite-borne relay user terminals is still in the initial and popularization stage. Due to many inconvenient factors in the application, such as many control parameters, many restrictions, and many sources of mission control package parameters, the application and promotion of t...
