Time Optimization Propagation Model of Meteorological Message Propagation and Information in Satellite Communication

Abstract

The sharing of meteorological message transmission of information in satellite communication was researched. It was found that the meteorological message information collected by satellite communication equipment was 100 characters, while the transmission capacity was 158 characters. The content of the information sent by each meteorological observation station was at most one and a half of meteorological message information. Each observation station received all the information sent by other stations and the relationship expression between the number of stations. Thus, the minimum propagation time was obtained, and the corresponding information transmission aggregation model was established. According to the transmission of the specified station, the rules were found, and the information of other stations received by each station in each round was obtained. The transmission scheme of the meteorological message of the master station was as follows. The first round adopted closedloop sequential transmission, that is $2\rightarrow 1,3 \rightarrow 2,\ldots, 1\rightarrow$ n, while from the second round, each round adopted the mode of transmission from the i+2 station to the i station ($i \leq n-2$). The mode 1$\rightarrow$n-1,2$\rightarrow$n was adopted by the first and second stations. Based on the result, a transmission model is established to find out the rule of station information sharing at a certain time. Finally, the number of stations N=9 was used to verify the feasibility of the propagation model.
