CLASS interference analysis system

The Communications Link Analysis and Simulation System (CLASS) project team of the NASA Goddard Space Flight Center Network Division, Code 530, has developed the CLASS interference analysis system (IAS) to support satellite communications scheduling by NASA's Network Control Center, IAS is designed to analyze communications problems arising from two or more spacecraft communicating with the same tracking and data relay satellite (TDRS) simultaneously. This system is currently composed of two major components: the CLASS automated conflict resolution system (ACRS) and the CLASS interference monitor (IM). ACRS is designed to be used in a mission-current manner, producing through interference estimates for any and all currently operating TDRS users. The IM is employed as a long-term interference predictor, taking planned spacecraft and producing broad-based statistical results concerning the resulting communications interference with and/or by other planned or existing spacecraft. Together, these two packages form a comprehensive tool for accurately analyzing potential interuser communications interference between concurrently operating space missions.<
