Space network communication method based on WIFI

Abstract

The invention provides a space network communication method based on WIFI. Specifically, a network topology structure which mainly comprises one main node and a plurality of slave nodes is built, wherein data communication between the main node and the slave nodes can be carried out based on the WI-FI standard; the main node and the slave nodes abide by network communication protocols, wherein the network communication protocols comprise the slave node access protocol, the main node active data sending protocol and the slave node active data sending and receiving protocol; a network communication protocol structure on which the network communication protocols are based comprises a data transmission layer, an interface layer and an application layer, wherein the data transmission layer has a data transparent transmission function based on the WI-FI standard, the interface layer serves as a data transmission channel between the data transmission layer and the application layer, and the application layer is responsible for terminal processing of data transmission. The space network communication method has higher suitability, flexibility and reliability and can be applied to fields like the minisatellite constellation formation communication field and the aircraft on-orbit service communication field.

Description

technical field [0001] The invention belongs to the field of space network communication, and in particular relates to a WIFI-based space network communication method, which is especially suitable for short-distance communication within a 3km range of small satellite constellations. Background technique [0002] The traditional small satellite constellation communication is specially designed, which not only requires a lot of manpower and material resources, but also prolongs the development cycle. The WI-FI standard has been widely used in various fields such as human daily life, industrial production, and service industries. The technology is relatively mature and the technology cost is relatively low; The short-distance communication requirements within the range of 3km of the satellite; the communication method based on the WI-FI standard adopts the anti-collision carrier sense multiple access mechanism, which has higher reliability and stability; because the satellite i...
