Turkish defense industry company Havelsan has achieved its 60th delivery of Ship Data Distribution Systems (GVDS), marking a significant milestone for domestically developed naval technology that serves as the heart of ships and submarines.
The software-based solutions company, which undertakes various responsibilities domestically and internationally, is strengthening platforms developed and produced within the Turkish defense industry.
The GVDS, also known as FLEETSTAR, developed with national capabilities, is called the Submarine Information Distribution System (DBDS), also known as SUBSTAR when used in submarines.
The GVDS and DBDS product family serves as the heart of modern naval platforms, providing data flow and system integration with high performance even under the most challenging conditions.
Havelsan completed its 60th delivery in the GVDS product family within 15 years of its establishment. The latest GVDS delivery passed factory acceptance tests with an A grade for use on MILGEM's eighth ship.
The Platform Data Distribution System (PDDS) collects, processes, and distributes data from sensors and systems on surface platforms to mission computers, Combat Management Systems (CMS), weapon systems, tactical sensors, and other subsystems. As the backbone of the platform, the PDDS ensures synchronized and reliable data flow across all subsystems during operations.
Havelsan offers multiple PDDS configurations for different vessel types: two 25U cabinet configurations for large platforms such as frigates and corvettes, 25U cabinet configurations for patrol vessels and missile boats, a 12U cabinet configuration for fast attack crafts and smaller platforms, and a compact PDDS unit for USVs and similar unmanned surface platforms.
The Submarine Data Distribution System (SDDS), specifically designed for submarine platforms, ensures real-time, reliable, and synchronized data flow between critical submarine subsystems such as tactical sensors (SONAR, RADAR, and periscopes), navigation systems, combat management systems, and weapon systems throughout the entire operation.
Key features include real-time data distribution with low-latency data transfer to all critical systems across the platform; redundant architecture with fault tolerance through redundant computing infrastructure with two cabinets or within a single cabinet, ensuring continuous operation; and multiple interface support, including Ethernet, RS-422, RS232/485, HDLC, Synchro, NTP, and STANAG HQ/1PPS.
The system provides data control and plausibility checks through intelligent data control, filtering, and prioritization algorithms for accurate and orderly data flow; simulation and black box functionality for sensor data simulation, data recording, and analysis support; and a modular and scalable architecture that is expandable and adaptable to different submarine classes.
The company, which designs data distribution systems for surface ships and submarines, made its first GVDS delivery 15 years ago to TCG Heybeliada, also known as MILGEM-1.
GVDS operates on a 24/7 basis on all ships and submarines, earning user appreciation with very high availability and low failure rates.
The total operational time of the GVDS and DBDS product family produced to date has exceeded 300 years.
Other ships and submarines in the Turkish Naval Forces inventory are waiting in the delivery queue for GVDS and DBDS system integration.
Havelsan successfully achieved an average of one system delivery per month over the past year.
The company increased the domestic contribution rate of the GVDS and DBDS product family to over 80 percent by developing subsystems, including Single Board Computer (SBC), Interface Cards, Time Card, Power and Backplane semi-finished cards, Time Server, and GNSS within the scope of nationalization.
Systems can collect data from INS, Gyro, GNSS, EM-Log, Doppler-Log, Echo Sounder, RADAR, periscopes, and meteorological sensors. Data distribution capabilities include Combat Management Systems (CMS), Weapon and Missile Control Systems, RADAR, Periscopes and Electro-optical Sensor Systems, Navigation and Chart Systems (ECDIS/WECDIS), and Communication and Tactical Data Link Systems.
The systems meet MIL-STD-810, MIL-STD-461, MIL-STD-1310 and MIL-STD-1399 approval standards.
The GVDS and DBDS, accepted as the heart of their platforms, have direct connections with many systems on the platform. These systems receive the data they need from GVDS and DBDS.
The system was designed, developed, produced, and applied to ships with the speed and performance to prepare the necessary data infrastructure for a ship to hit what it fires at accurately, even in rough seas during bad weather.
Havelsan provides the necessary infrastructure for tactical sensors like radar and weapon systems like guns to operate at the highest performance even under the worst conditions in a ship environment.
The company produces most of the electronic card needs of the GVDS/DBDS product family and all of the software and mechanical needs with original engineering solutions.
