Spectrum Considerations for Satellites and Ramifications for RF Interference

Choosing the right frequencies is critical to proper operation of small satellites and essential to reducing RF interference. Satellites rely on radio frequency spectrum for telemetry, tracking and control (TT&C) and data downlinks. This spectrum requirement applies not only to the satellites but also for the associated ground stations providing TT&C functions. Small satellites place unique demands on the regulatory process, which is due to their short time in development. Selecting the proper transmit and receive frequencies in bands that are allocated for a small satellite application and operations type is essential to successful operation of the satellite and reduction of radio frequency interference (RFI).
