Narrowband satellite communication system and method

Abstract

The invention discloses a narrowband satellite communication system and method, and the method comprises the steps: receiving first to-be-transmitted data from a first data transmission interface through a central processing module, enabling the central processing module to carry out the subpackaging of the first to-be-transmitted data, and obtaining a plurality of first to-be-transmitted data packets; enabling the central processing module to sequentially send a plurality of first to-be-transmitted data packets to a plurality of corresponding satellite communication sub-modules according to a preset satellite communication priority ranking table, and enabling the plurality of corresponding satellite communication sub-modules to respectively perform protocol conversion processing on the plurality of first to-be-transmitted data packets to obtain a plurality of corresponding first target to-be-transmitted data packets; enabling the plurality of corresponding satellite communication sub-modules to respectively perform satellite network transmission on the plurality of first target to-be-transmitted data packets, so the data transmission rate of the narrowband satellite communication system can be greatly improved, and meanwhile, the transmission delay and the transmission interval are greatly reduced.

Description

Technical field[0001]The present invention relates to the field of satellite communication, and more particularly to a narrowband satellite communication system and method.Background technique[0002]With the rapid development of the Internet of Things, more and more equipment have the needs of the network. However, the existing cellular mobile communication network only covers 5% of the land area on the earth, and the large-scale areas such as oceans, deserts, mountains, etc. are not covered, so the monitoring equipment, large machinery, drones, no one in these areas. Internet accessories such as boats, animal monitors can only be networked by satellite communication.[0003]At present, mainstream satellite communication equipment is mainly divided into narrowband satellite communication equipment and broadband satellite communication equipment. Among them, the narrowband satellite communication device is small, light, low price, low data transmission rate; broadband satellite communic...

AI Technical Summary

Problems solved by technology

[0004] However, there are still deficiencies in the application of these devices in the field of satellite Internet of Things. The main disadvantages are that the data transmission speed of these devices is too low, the transmission delay is high, and the message transmission interval is large.

This makes users have to make corresponding sacrifices in terms of functions when using them, such as reducing the amount of transmitted data and increasing the interval between message transmissions

At the same time, it also limits the application scenarios of narrowband satellite communication equipment. For example, unmanned aerial vehicles, unmanned ships, etc. have high data transmission delay and certain requirements for data transmission rate, so the current narrowband satellite communication equipment cannot be used.
