3 Terms and definitions

The following terms and definitions apply to this document:

3:1

Spacelink

A communication link between a spacecraft and the corresponding ground system or between two spacecraft:

Note: A space link contains one or more unidirectional or bidirectional physical channels:

3:2

Proximity space linkproximityspacelink

Proximity linkproximitylink

It is a communication link for direct communication between spacecraft in the distance range of 1m to 100000km:

Used for communication links 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

Asynchronous datalink

A data link composed of variable length and not necessarily continuous transmission PLTU:

3:4

Caller caler

The initiator of the adjacent space link establishment process and the management subject of the session negotiation process:
