A link budget is the summation of all of the power gains and losses that occur in a communication system. A link budget is a design aid and is one factor used to help ensure the information is received intelligibly. To figure out if a signal can be received at any given location, we need to determine what the received power will be.

Japan’s OMOTENASHI, the world’s smallest moon lander, will have an X-band and UHF communication system, although it will not carry an amateur band transponder. OMOTENASHI is a 6U CubeSat set for launch via a NASA SLS rocket as early as February 2022. It will have a mission period of from 4 to 5 days. The name is an acronym for Outstanding Moon Exploration Technologies demonstrated by Nano Semi-Hard Impactor. Wataru Torii of the Japan Aerospace Exploration Agency (JAXA) Ham Radio Club, JQ1ZVI, said radio amateurs can play a role in gathering data from the spacecraft.
