technical field

The utility model relates to the field of wireless communication, in particular to a Beidou data sending device based on a multi-card mechanism.

Background technique

The Beidou navigation test system is the first generation of satellite navigation and positioning system independently developed and built by my country. It is the third actually operating navigation and positioning system in the world after the US "GPS" system and the Russian "GLONASS" system. In addition to the characteristics of large coverage, no communication blind spots, safety and reliability, Beidou satellite communication also has a special short message communication function, which enables users to realize short message communication through satellites, and is not affected by terrain conditions and environmental climate Impact. This function can be used to solve short message communication in sparsely populated rural areas, pastoral areas, remote mountainous areas, sea areas, and areas that cannot be covered by existing wired and wireless communication networks, as well as emergency communications for disasters.

With the development of my country's Beidou business and the extensive use of Beidou short message functions, there are still the following limitations in the application of Beidou short messages in remote data transmission and control: using short message communication, there is a communication capacity limit for one communication, That is, the length of each communication content is limited, and the communication capacity is small. In general, the civilian communication capacity is only about 70 bytes; the communication frequency is limited, that is, there is a certain time interval between every two communications. Moreover, this time interval is relatively large. Under normal circumstances, the civilian communication cycle is about 60 seconds. That is, the Beidou short message system has a small communication capacity and a low communication frequency. These characteristics make the amount of data transmitted in real time generally small. When a large amount of data needs to be transmitted in real time, the transmission data rate is far from enough, and in a The Beidou communication system can only send data once in a cycle, and the transmission efficiency is low.
