Ku-band SATCOM Data Link(KuSDL) Predator Reconnaissance System

The KuSDL utilizes commercial, geostationary satellites to effect fullduplex SATCOM linking the Predator UAV to a remote controlexploritation complex. The command link provides real-time control anddata while the return link transfers real-time EO, IR or SAR motion videoto the exploitation facilities.

geosynchronous satellites. Lease,revenue arrangements and spot beamlocations all established long beforemission initiation.

III) In-theater exploitation and controlcomplex, including transportablesatellite earth terminal (IESS -208,Type E2) with full duplex Ku-bandreceive and transmit capability.Complex would include exploitationcapability and full connectivity to in-theater voice communicationscomplex. Remote pilot (GCS)accomplishes ATC with authoritiesnear flight-path via data links andonboard AN/ARC-210 radio.
