Modeling potential transponder problems early in the design process can save expensive impairments in the finished product. Because the economics associated with link performance are severe (even a small amount of degradation will affect a system's data rate or coverage, both of which are related to capital and operating expenses), it is crucial to have all of the system design parameters optimized before committing to implementation. Additionally, when things go wrong during construction or initial operation, a simulation model can be used to track down the offending element. The simulation is also useful for pretesting any corrective action before implementation, either on the ground or in space. This article describes many of the real world impairments that affect the performance of a satellite based transponder communication link. By carefully implementing these effects via computer simulation, optimum operating points can be determined and and potential problems corrected in the design process before costly mistakes occur in the finished product.
