The DTS-K from Leonardo DRS is a Link 11 Data Terminal Set that integrates a data link modem and cryptographic equipment in one chassis for airborne (fixed or rotary wing) or platforms with size and weight constraints. It generates both Convention Link 11 Waveform (CLEW), and the Single-tone Link 11 Waveform (SLEW) for improved performance in the presence of multipath commonly found in the HF environment. This system is based on a VME bus-based chassis and circuit boards with proprietary software, which enables the unit to perform as a Link 11 data terminal set with the KG-11 cryptographic functions of a Link 11 network NCS or Picket. It is certified by the National Security Agency (NSA).
The DTS-K has three primary functions in a Tactical Data Information Link (TADIL) network. First, the DTS-K interfaces to the tactical computer for network message traffic to pass from one net station to another. Second, it performs encryption and decryption of the message traffic to NSA Communication Security (COMSEC) standards. Finally, the DTS-K phase modulates and demodulates the encrypted data to audio tones for transmission and reception by either HF or UHF radios.
The DTS-K has a remote control (e.g., from the cockpit) interface that enables remote operation of the unit via a control head or computer over an RS-232 interface. It requires a DC supply from 24 to 32 V and consumes less than 18 W of power. The system is available in an enclosure that measures 19.55 x 12.39 x 32.05 cm and is designed for demanding airborne environments.
