Onboard Sonar System (BOSS)


The Integrated Sonar System (BOSS) Project aims to fully integrate BOSS, a sonar system to be developed for surface platforms, into the Combat Management System (SYS). Within the scope of the project, BOSS that can operate Monostatic, Bistatic and Multistatic will be developed. BOSS will consist of a Medium Frequency Body Mounted Sonar subsystem and a Towable Low Frequency Sonar (ÇAFSON) simulator.

The main purpose of the project is to ensure the coordinated operation of multiple sonar systems with national resources and to develop the Multistatic Sonar capability, which provides target detection from long distances. The project is carried out in cooperation with the Presidency of Defense Industries, Scientific and Technological Research Council of Turkey (TUBITAK), Marmara Research Center (MAM) and Meteksan Defense. Within the scope of the project, Bistatic/Multistatic Sonar, ÇAFSON, BOSS Simulators, multistatic sonar performance modeling, console, SYS alignment, target motion analysis, data recording, system management and classification software are developed. In addition, the Digital Underwater Telephone within the scope of the project is being developed under the responsibility of the institution.

The BOSS Project is an important step to increase the underwater activities of surface platforms and to contribute to the acquisition of national capabilities in the field of maritime security. This project is an example of Turkey's efforts to develop domestic and national technologies in the defense industry.

MILSEC 4 - Secure IP Terminal


While the MİLSEC-4 terminal offers an up-to-date solution for next-generation secure communication (voice, data and video) in IP networks, it provides an uninterrupted communication service by maintaining the compatibility of secure voice communication in PSTN networks with PSTN secure phones in use.

Configuration, surveillance and software update processes of MILSEC-4 terminals are carried out securely remotely using the Security Management Center (GYM). MİLSEC-4 terminal is capable of IP Network Key Loading (IPAAY) through secure communication with GYM without the need for an additional device.

MİLSEC-4 terminals are interoperable with MİLSEC-1A and MİLSEC-2 phones and offer the opportunity to replace MİLSEC-1A and MİLSEC-2 phones without interruption in the gradual transformation of PSTN networks to next generation IP networks.
