Link budget analysis for a proposed Cubesat Earth observation mission

A Cubesat with payload for characterizing electromagnetic and geomagnetic field is proposed. We review the link budget requirements for this mission to enable high data rate communication between a low Earth orbiting satellite and an Earth station. Multiple frequency bands, typically used in Cubesat operations, are evaluated, including attenuation and other link impairments along the communication path. We also review the communication parameters in currently deployed and active Cubesat missions.
