Minerva Engineering's Tactical Systems division has experience in numerous elements of tactical HMMWV shelter systems. The TS division will modify or re-engineer the shelter system to accommodate new components and/or rack configurations. Our engineers have extensive DOD vehicle integration experience to include fielded tactical hardware in operation today in OIF/OEF.

Army Tactical Terminal Control System (TTCS, AN/TSQ-198)

Tactical Terminal Control System (TTCS)

System Description:

The Army Tactical Terminal Control System (TTCS, AN/TSQ-198) performs air traffic control services at forward locations in the combat theater. The TTCS is a mobile communication system. It provides air traffic services at remote landing, drop, and pickup zones. TTCS equipped units will provide air traffic services for aviation assets conducting reconnaissance, maneuver, medical evacuation, logistics, and intelligence operations. The current configuration of the TTCS consists of a M998 High Mobility Multipurpose Wheeled Vehicle, Cargo/Troop Carrier (HMMWV) containing an AN/GRC-206(V)4 Radio Communication System (Radio System), and a M1101 High Mobility Trailer.

Functional Description:

Tactical Terminal Control System (TTCS)

The HMMWV contains the Radio System, a Satellite Signals Navigation Set (Global Positioning System (GPS) Rcvr), the Meteorological Measuring System (MMS), and a Signal Data Converter. It also contains the HF Whip Antenna, HF Antenna Base, the HF Antenna Coupler, the HF PA Coupler, the VHF-FM antenna, VHF/UHF-AM antenna, and the Remote GPS Antenna. The 1 km (3281 ft) Tactical Fiber Optical Cable Assembly (TFOCA) and a Signal Light Kit are also stored on the HMMWV. The Radio System contains one VHF-FM SINCGARS radio set with two RT's, one HF-SSB, one AN/ARC-220(V)1 HF radio set, one SATCOM radio and two VHF/UHF-AM radio sets. The two VHF/UHF-AM radio sets have UHF HAVE QUICK II capability and receive Time-of-Day signals from the GPS Rcvr. The VHF/UHF-AM radios can be used to synchronize the clocks in other HAVE QUICK radios for frequency hopping. The two VHF/UHF-AM radio sets and the SATCOM radio all have embedded COMSEC. One TSEC/KY-99 Speech Security device and one TSEC/KY-100 Audio-Data Security device provide COMSEC for use with the AN/PRC-138 Harris HF and AN/ARC-220 Rockwell HF respectively.

The Radio System, with the exception of the VHF-FM radio set and the AN/ARC-220 ALE, can be controlled and operated using either of the two Radio Set Controls (RSC) provided. The SINCGARS VHF-FM radio set and the AN/ARC-220 ALE can be operated from either of the two RSCs, but can only be controlled from the individual RT. Four handsets are provided for voice communications. CAT5 enables remote operation of the TTCS up to 50M from the vehicle. TFOCA II enables remote operation of the TTCS up to 1000M from the vehicle. Cables necessary to interconnect the radios and ancillary equipment are also provided.

The trailer contains a 5 kilowatt 240 Vac diesel generator (Generator Set), two Antenna Elevator Groups, three Accessory Kits, a Remote HF Antenna Accessory Kit, a VHF/UHF-AM Antenna Radial Kit, and a HF Near Vertical Incident Skywave (HF NVIS) antenna.
