Alice-SK
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:
- NOAA (POES);
- MetOp;
- FengYun;
- NPOESS (to be launched in 2013)
