TSQ-190

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 sensitive compartmented intelligence (SCI) and 6 collateral TOP SECRET and below). These have digital rates from 4.8 to 512 kbps per channel using the C, Ku, or X frequency bands, which are far too low for large volume data from such sensors as imagery intelligence.
