| 释义 |
A satellite bus or spacecraft bus is a general model on which multiple-production satellite spacecraft are often based. The bus is the infrastructure of the spacecraft, usually providing locations for the payload (typically space experiments or instruments). Bus-derived satellites are opposed to one-off, or specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission.[1][2][3][4] They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples{{main|Comparison of satellite buses}} (only commercially available models)Some satellite bus examples include:
Components{{Main article|Spacecraft#Subsystems}}A bus typically consists of the following subsystems:[6]
