سؤال 80

What is the purpose of digital store-and-forward functions on an amateur radio satellite?

  1. To upload operational software for the transponder
  2. To delay download of telemetry between satellites
  3. To hold digital messages in the satellite for later downloadپاسخ درست
  4. To relay messages between satellites

توضیح

A low Earth orbit satellite is rarely in view of both correspondents at once, so a store-and-forward payload accepts uploaded messages, keeps them in onboard memory, and downloads them on a later pass over the recipient. Uploading transponder software and passing traffic between satellites are different functions.
