UPMSat-2

Communications

  • Ground-satellite communications will be carried out in the UHF band, 400MHz.
  • The flight system will consist of a transmitter/receiver, with modem, and an antenna with an omnidirectional radiation lobe.
  • The receiver consumption will be minimal, in the order of 2W (it must remain always on).
  • The transmitter will have a 50W power stage (TBC), which will only operate during the periods of connection with the ground station (around 10min).
  • The downlink speed will be at least 19,200 bsec.
  • For debugging and ground testing, the satellite will have a connector that allows access to the OBC and other relevant signals.
