Power budget
In telecommunication, a power budget (or system budget) is the allocation, within a system, of available transmitter power output to achieve the desired effective radiated power, among the various functions that need to be performed.
An example of a power budget in a communications satellite is the allocation of available power among various functions, such as maintaining satellite orientation, maintaining orbital control, performing signal reception, and performing signal transmission.
