The original satellite terminal for the TROJAN SPIRIT]] intelligence communications system, the AN/TSQ-190 (V) is a transportable earth station. In the first version, it supported 14 circuits (8 compartmented control system|sensitive compartmented intelligence (SCI)]] and 6 classified information|collateral TOP SECRET and below]]). These have digital rates from 4.8 to 512 kbps per channel using the C, Ku, or X IEEE frequency bands|frequency bands]], which are far too low for large volume data from such sensors as imagery intelligence]]. Physically, it came in two shelter packages, carried on M-1097 heavy HMMWV|HHMMWV]] light trucks. The Enhanced Combat Vehicle (ECV) is replacing the HHMMWV. The antenna and immediately associated radio equipment would differ depending on the level of headquarters being supported, but the systems were otherwise alike. |
