What do the letters in a satellite’s mode designator specify?

  1. Power limits for uplink and downlink transmissions
  2. The location of the ground control station
  3. The polarization of uplink and downlink signals
  4. The uplink and downlink frequency rangesپاسخ درست

توضیح

Each letter in a mode designator stands for a band, the first for the uplink and the second for the downlink, so V/U means a 2 meter uplink and a 70 centimeter downlink. The designator says nothing about power limits, ground station location, or polarization.
