What is the purpose of digital store-and-forward functions on an amateur radio satellite?
- A.To upload operational software for the transponder
- B.To delay download of telemetry between satellites
- C.To hold digital messages in the satellite for later download (correct answer)
- D.To relay messages between satellites
WhyDigital store-and-forward functions let an amateur radio satellite hold digital messages in memory for later download. A digital store-and-forward function lets a satellite hold digital messages in its own memory so ground stations that aren't in view of each other, or in view of the satellite at the same time, can still exchange traffic, with the satellite delivering each message on a later pass, answer C. It isn't for uploading transponder software, delaying telemetry, or relaying live traffic directly between satellites, those are different functions from storing a message for later download.
