Communication system based on Beidou system and communication method thereof

The invention discloses a communication system based on a Beidou system, and the system comprises a data splitting module which is used for splitting to-be-transmitted data, and forming a plurality ofdata segments; a data information extraction module used for extracting key data information in each data segment; a data compression module used for compressing each data segment and the key data information in the data segment; a data transmission module used for transmitting the compressed data segment and the key data information; a data verification module used for verifying the received data segment by using the key data information; and a data reorganization module used for reorganizing the verified data segments to obtain complete data. According to the invention, the defects in theprior art can be improved, and the data transmission efficiency is improved on the premise of ensuring the transmission accuracy. 本发明公开了一种基于北斗系统的通讯系统，包括数据拆分模块，用于对待传输的数据进行拆分，形成若干个数据段；数据信息提取模块，用于对每个数据段中的关键数据信息进行提取；数据压缩模块，用于分别对每个数
