3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Space link Communication links between spacecraft and between spacecraft and the ground. Note. A space link includes one or more one-way or two-way physical channels. 3.2 Adjacent space link Adjacent link It is a communication link for direct communication between spacecraft in the distance range of 1m to 100,000km. Used for the communication link between the main spacecraft and the auxiliary spacecraft. Note. Short-distance, two-way, fixed or mobile radio frequency links are mainly used to carry out between detectors, landers, patrol devices, orbital constellations, and orbital repeaters. Communication has the characteristics of small delay, medium signal energy (not weak signal), independent conversation and short time. 3.3 Adjacent link transmission unit A data unit composed of the CCSDS adjacent space link transmission frame plus ASM and CRC.
