DATAS - Submarine Tactical Simulator
It is a computer-based training simulator developed for submarine commanders and combat crews, with the aim of training tactical and operational methods. Considering the importance of the “applied training” approach, the system allows the creation of different training scenarios for different tactical behaviors such as scanning, engagement, attack and evasion.
DATAS, an onshore system, consists of three physical parts:
- Training control room: It is the place where the trainers control the simulation system, prepare the scenarios to be used in the training and run the training scenarios.
- Switchboard room: It is the place where the trained personnel take the tactical and operational decisions and perform the training.
- Debriefing room: It is the place where the trainers evaluate the training performance on the wide screen with the help of debriefing and analysis tools within the simulation.
GENERAL ABILITIES
- Simulation of submarine switchboard system and consoles
- Cylindrical array sonar
- Flat array sonar
- Passive rangefinder sonar
- Intercept passive sonar
- Active sonar
- Radar and ESM (Electronic Support Measures)
- LINK/ROL-11
- Torpedo and guided missile
DATAS

- Submarine navigation simulation
- Trace table simulation
- Underwater environment modeling
- Platform and ambient noise modeling
- Acoustic propagation modeling (Normal Mode and Ray Trace)
- Target modeling with autonomous behavior
- Submarine Defense Warfare
- Ability to apply DSH tactics

SHIP D/G - Onboard Automatic D/G System
The Ship D/G System uses D/G coils that are conveniently placed on the ship, creating an equal-sized but opposite direction to the ship's magnetic track and suppressing the ship's magnetic track. Depending on the position and route of the ship, currents at appropriate values are printed on the D/G coils and the magnetic trace of the ship is kept within the desired limits. The magnetic trace of the ship with the D/G System active decreases and the system shortens the detection distance of the magnetic sensors in the mines. Thus, the risk of mine explosion is reduced. Ship D/G System serves on Turkish Navy Island Class corvettes.
SATEL - Underwater Telephone
Underwater Telephone is a communication system, all of which are microprocessor-controlled, providing communication between surface/underwater ships via underwater acoustic waves.
The use of upper and lower sideband (SSB treatment) with suppressed carrier frequency allows to obtain high signal-to-noise ratio at high transmission bandwidth. The carrier frequency is fixed (quartz stabilized) and is designed as NATO frequency or adjustable between 2-40 kHz for the upper sideband and 5-43 kHz for the lower sideband.
When operating within a convoy, it is possible to communicate with the appropriate counter station using different frequencies.
The transmission bandwidth is reduced in telegraph mode for optimum signal-to-noise ratio. The transducer group is connected to the main unit with the help of an interconnection box.
The control and display unit is located in the integrated navigation rack
- Hydrostatic pressure: equipment subjected to hydrostatic pressure is resistant to 5 MPa (50 bar). Test for these devices
pressure can be up to 6.25 MPa (62.5 bar). - underwater telephone and telegraph system
- Transmitting and receiving amplitude modulated sound waves in water with transducers
- Communication with appropriate counter stations
- Selectable operating frequencies
- Independent audit and monitoring
- Air-cooled system during operation
- Condensation prevention in stand-by
- Interface with communication system for recording of audio signals

- Adjustable carrier frequency (adjustable in 1 Hz steps)
- Frequency is displayed on the integrated LCD as a numerical value and with a pointer.
- Upper sideband (USB): 2-40 kHz
- Lower sideband (LSB): 5-43 kHz
- Power output: 100W at 35 Ω
