Ka-band SATCOM in A2C2S

The rapid growth of the digitized battlefield is placing greater demands on spectrum use. High bandwidth/data rate requirements and non-line-of-sight communication links move one toward the use of high frequency and high bandwidth satellite communications. Wideband gapfiller system, WGS, is a SATCOM system filling this role and previous analysis has been devoted to ground terminals on the pause and on the move. We consider use of WGS for rotary winged aircraft, in particular, for the Army Airborne Command and Control System, A2C2S, which employs an UH-60 as an airborne command post. This system will be deployed for both military and homeland security use. The problems associated with antenna placement and rotor modulation are presented and discussed. Link budgets are computed to demonstrate the asymmetric link capabilities and potential waveform solutions for defeating rotor blockage are presented.
