Description
Technical Field
The application belongs to the technical field of deep space exploration, and particularly relates to a method and a device for judging the delayed transmission control effect of multiple spacecrafts.
Background
In the multi-spacecraft control process, one survey station is generally adopted to implement command control on one spacecraft, and the command control of a plurality of spacecrafts is relatively independent. However, when the deep space exploration task or the measurement and control resources are in shortage, in order to save the ground measurement and control resources, the ground center realizes the multi-spacecraft control by a transmission command mode, namely: the ground sends an instruction to a certain spacecraft A through a survey station, and the instruction of another spacecraft B is sent to the spacecraft A from the ground and forwarded to the spacecraft B by the spacecraft A. The generation transmission command is divided into real time transmission and delay generation transmission, wherein the real time transmission and the delay generation transmission are adopted, and the spacecraft A immediately transmits to the spacecraft B after receiving the command; after receiving the instruction, the spacecraft A is switched to the spacecraft B at regular time according to the delay time. For the multi-spacecraft delay transmission instruction, how to judge the execution condition of the multi-spacecraft instruction is a relatively complex problem, and a multi-spacecraft delay transmission control effect judging method needs to be designed to realize accurate and comprehensive judgment of the instruction transmission process and result.
In the existing multi-spacecraft control process, an instruction forwarding control mode of a relay communication satellite is mostly adopted. In this control mode, the relay communication satellite is only a forwarding path of the instruction, the execution condition of the instruction is not judged, and the ground center only judges whether the target spacecraft normally receives the instruction and the final execution condition of the instruction. The ground center does not judge the relay satellite forwarding process, so that the conditions of instruction forwarding and execution cannot be comprehensively judged.
