Embodiment 1

[0028] According to an embodiment of the present invention, an embodiment of a method for determining a command sending delay of a spacecraft is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer such as a set of computer-executable instructions system, and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0029] figure 1 It is a flow chart of a method for determining a command sending delay of a spacecraft according to an embodiment of the present invention. like figure 1 As shown, the method may include the following steps:

[0030] Step S102, acquiring the first period of time delay for the target command to be sent to the relay satellite via the ground control center.

[0031] In the technical solution provided by step S102 of the present invention, the ground control c...

Embodiment 2

[0067] The technical solutions of the embodiments of the present invention are illustrated below in combination with preferred implementation modes.

[0068] In this embodiment, since the communication characteristics of the sending equipment of the ground survey station are different from those of the forwarding equipment of the lunar relay satellite: the processing mechanism and delay of the two are different, and the sending code rate is also different. Among them, the ground control center The content of the instruction code sent to the lunar relay satellite by the ground station is different from the instruction code transmitted by the lunar relay satellite to the target spacecraft, and the length of the instruction code is also different. Therefore, this embodiment adopts a "two-stage" method to calculate the time delay for the ground control center to transmit to the target spacecraft via the relay satellite. The above-mentioned "two-stage method" refers to the time del...

Embodiment 3

[0096] The embodiment of the present invention also provides a device for determining the delay in sending commands of the spacecraft. It should be noted that the apparatus for determining a delay in sending a command of a spacecraft in this embodiment can be used to implement the method for determining a delay in sending a command of a spacecraft in an embodiment of the present invention.

[0097] image 3 It is a schematic diagram of an apparatus for determining a delay in sending commands of a spacecraft according to an embodiment of the present invention. like image 3 As shown, the device 30 for determining the command sending delay of the spacecraft may include: a first acquiring unit 31 , a second acquiring unit 32 and an accumulating unit 33 .

[0098] The first obtaining unit 31 is configured to obtain the first period of time delay when the target instruction is sent to the relay satellite via the ground control center.

[0099] The second obtaining unit 32 is con...

Abstract

The invention discloses a method and a device for determining instruction sending time delay of a spacecraft and a storage medium. The method comprises the following steps: acquiring a first section of time delay sent to a relay satellite by a target instruction through a ground control center; obtaining a second time delay of the target instruction processed by the relay star and forwarded to thetarget spacecraft; and accumulating the first section of time delay and the second section of time delay to obtain a target time delay of sending a target instruction to the target spacecraft by theground control center. According to the invention, the technical problem of low determination precision of the instruction sending time delay of the spacecraft is solved.

Description

technical field [0001] The present invention relates to the technical field of computer communication, and in particular, to a method, device and storage medium for determining a command sending delay of a spacecraft. Background technique [0002] At present, the following two methods can be used to determine the delay in sending commands of the spacecraft: [0003] (1) In the control process of some spacecraft, the ground directly sends commands to the spacecraft through the ground station, without passing through the relay communication satellite, and the spacecraft runs on a relatively fixed orbit. In this way, before the launch of the spacecraft, the ground control center communicates with the ground station and the spacecraft to test the time delay of the control loop, and directly applies the test results to the control process of the spacecraft’s in-orbit flight. However, this method is suitable for simple control links without relay satellites participating in the c...
