Content description
Marks the beginning of a message, the content is $S (0x2424) the protocol version number followed by the message. The version number adopts the form of "major version number.minor version number", the first byte is the major version number, and the second byte is the minor version number. The protocol version number of this appendix is 1.0 (0x0100)

The data segment consists of parameter items. Parameter items generally have a fixed length. For parameters with non-fixed lengths, the corresponding length parameter item is used to specify the specific length of the parameter. When a parameter is missing, the value of its length parameter item is 0 (0x0000).
The parameter items of each message are different according to the data content. The cyclic redundancy check code is used for verification. The verified data segment starts from the first byte after the start identifier and ends at the end of the parameter segment
The message is transmitted in bytes, using the data type specified in Table A.2. Table A.2

Message content
The message grouping of base station information data, equipment information data and satellite status data is shown in Table A3. Each message group consists of two or four messages. The setting message is completed by the data center to control the base station and set various parameters of the base station; the response message is completed by the base station to return the result status of the setting message; the acquisition message is completed by the data center to obtain various information and data of the base station; the reply message is completed by the base station to return the information required to obtain the message.
