Abstract

A Beidou long message transmitting device and a method thereof are provided. That transmitting device comprises a plurality of Beidou virtual smart cards, a single chip microcomputer, a baseband processing unit, an up-down frequency conversion circuit, a low noise amplifier, a pow amplification circuit and a Beidou transmitting antenna. The transmitting device splits the long message to be transmitted into a plurality of short messages, and each short message matches a transmitting authentication code and is transmitted to the Beidou satellite after being packed. The invention realizes the function of quickly sending the Beidou long message through a plurality of preset satellite inbound transmission authentication codes of Beidou users in advance and a special packing protocol, and the sending device has the advantages of simple hardware design, low manufacturing cost, greatly improving the user experience and widening the use scene.

Description

technical field [0001] The invention relates to the field of Beidou No. 2 communication, in particular to a Beidou long message sending device and method. Background technique [0002] The Beidou-2 satellite navigation system (BD2, Beidou-2) is a global satellite navigation system independently developed by China. As of the end of 2012, there are currently 14 satellites serving the Asia-Pacific region, including 5 GEO satellites, 5 IGSO satellites and 4 MEO satellites. Among them, the five GEO satellites of Beidou-2 provide short message communication functions, and other satellites provide navigation and positioning functions. 5 GEO satellites, each of which contains 2 independent beam signals, that is, a total of 10 independent beam signals provide short message communication services. [0003] The Beidou user machine was limited by the system design at the time. Each user machine was equipped with a Beidou user IC card, and the Beidou user machine was limited by the fre...
