Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] It should be noted that a plurality referred to in the present invention refers to two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship. In...

Abstract

The invention provides a communication synchronization method, device and equipment, which are used to solve the problem in the prior art that the synchronization performance is poor and affects the efficiency of satellite communication. The method is applied to a terminal device, including: obtaining the satellite ephemeris of the target satellite, and determining the first position of the target satellite at the first time based on the obtained satellite ephemeris when receiving the synchronization signal sent by the target satellite at the first time. position; according to the first position of the target satellite and the satellite ephemeris, determine the second moment to send the response signal of the synchronization signal to the target satellite, so that the target satellite can receive the response signal when it moves to the second position; The time difference between the third moment and the second moment corresponding to the second position determines the advance time required for the terminal device to send communication data to the target satellite.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication synchronization method, device and equipment. Background technique [0002] Satellite communication uses communication satellites as relay stations to forward microwave signals to realize microwave relay communication between multiple ground terminal equipment, such as ground stations. Frequent data interaction is required between satellites and ground stations. [0003] At present, in order to ensure that the data transmitted between the satellite and the ground station can be reached, the time service time corresponding to the satellite is usually used to correct the local time of the ground station, so as to unify the time of the ground station and the time of the satellite. However, in satellite communication, the data transmission process needs to go through two links, the uplink and the downlink, and the transmission delay is relatively large....
