Universal Alice-SC™ ground station is intended for receiving and processing of the imagery transmitted from polar-orbital satellites in 1.7GHz frequency.

The station provides for the RS data reception and processing from the following satellites:

  • MetOp
  • FengYun
  • NPOESS (to be launched in 2013)

Alice-SC™ installation requirements

To assure the best footprint, the horizon for the antenna system should be open from 5 degrees of elevation upwards in all directions.

For quality reception the absence of radio interference at 1670-1710 MHz is essential (can be caused by transmitters of radio relay and troposphere communication services).

Installation site of the PC and the control unit (laboratory part of the systems) depends on the connecting cables length (maximum 50 m) and how they are laid towards the antenna.
