The invention provides a method for designing a space-based measurement and
control data format adapted to a Beidou short message, comprising the following steps:
telemetry data format definition: framing is completed through nested packaging to obtain a
telemetry frame, the frame length of the
telemetry data is within a 240
Byte limit, a direct short message
insertion mode is adopted, and the telemetry frame is divided into containing an
insertion field and not containing the
insertion field; direct instruction format definition: the length does not exceed the 240
Byte frame of the Beidou short message, a direct short message insertion mode is used, and a
remote control instruction is composed of a guide code, an
instruction code, an execution sequence and an end sequence; data injectioninstruction format definition: a data injection instruction consists of the guide code, length information, an injection
instruction code and the end sequence, moreover, when the injection instructioncode exceeds 226
Byte, the code is disassembled into multiple packages for sending, and an odd-even check redundancy packet is added. According to the method in the invention, the characteristics ofthe Beidou short message is analyzed, the instruction formats are all subjected to an
adaptive design, and a
data format support is provided for
spacecraft measurement and control management based onthe Beidou short message.
