System accuracy is an important issue in control system design. The design goals for the different subsystems of a control system are often derived from 'rolling down' the total allowable error in the response of the control system to the different subsystems. Once the attainable subsystem errors are known (from analysis and/or tests), these values need to be 'rolled up' in order to determine the overall attainable system accuracy. The iterative process of rolling down the requirements, rolling up the attainable values, rolling down reviewed requirements, etc., is termed error budgeting. This paper defines different error budgeting approaches and illustrates some of the most important aspects by means of error budgeting for a satellite inertial measurement system.
