CTD Probe System
We are exploring the depths of the seas with our CTD sensor!
The CTD (Conductivity, Temperature, Depth) Probe System was developed through collaboration between STM and BAUMIND, a subsidiary of Bahçeşehir University, marking the first time such a system has been produced domestically in Türkiye using national resources and capabilities.
Designed to precisely measure the fundamental physical properties of seawater, conductivity, temperature, and pressure, the CTD Probe provides critical data for both defense and scientific underwater applications. Beyond these primary measurements, the system’s integrated processor calculates derived parameters in real time, such as sound speed, salinity, and specific gravity, enabling accurate modeling of underwater sound propagation essential for sonar system performance.
Unlike similar systems worldwide, the CTD Probe includes a three-axis inertial measurement unit (IMU), delivering real-time orientation data for both the system itself and the platform it is integrated with, further enhancing operational effectiveness.
The system is versatile and can be deployed on surface and submarine vessels, unmanned maritime vehicles, and scientific research platforms. It stands out with its robust structural design, broad operational range, and proven reliability, having successfully passed hydrostatic pressure and field testing.
Additionally, the project has led to the development of single-use measurement devices capable of generating depth-dependent temperature and sound velocity profiles. These solutions are suitable not only for military applications but also for environmental monitoring, marine mapping, and civilian oceanographic research.
In a significant example of university–industry collaboration, the Ministry of Agriculture and Forestry’s Trabzon Central Fisheries Research Institute Directorate became the first user of the CTD Probe system under a contract signed in 2025. The system will support academic studies in the fisheries sector by analyzing the physical characteristics of seawater.
Ultimately, the CTD Probe System contributes to reducing Türkiye’s dependency on foreign technologies in ocean sciences while strengthening the operational capabilities of submarines and other maritime platforms. Nationally developed critical systems like the CTD Probe are expected to play vital roles in future projects for the Turkish Naval Forces Command as well as in various scientific research endeavors.
Other Areas of Activity
While prioritizing Türkiye’s defense industry requirements, we diversify our technology-based operations to address the needs of both the public and private sectors, delivering innovative solutions across a broad spectrum.
