Equipment for NAVDAT system

2023: Product Announcement

On December 8, 2023, Rostec"" announced the creation of the first Russia in equipment for a broadband data network from onshore stations to NAVDAT vessels. The devices were developed at the Research Institute "Holding," NeptuneRoselectronics which is part of Rostec.

The Neptune Research Institute has developed a radio frequency amplifier for NAVDAT, as well as a broadband antenna-feeder device with an antenna-matching device. As noted in Rostec, prototypes of the equipment were successfully tested, the developers managed to ensure the transmission of complex NAVDAT broadband signals from shore to sea in the operating frequency range of 495.0-505.0 kHz.

Rostec called NAVDAT a promising method for transmitting information on safety at sea based on digital broadcasting. The system implements modern multiple modulation methods, multi-frequency signals, as well as redundant coding methods. By the end of 2023, NAVDAT stations are deployed off the coasts of Europe and Asia and operate in test mode.

According to the results of testing NAVDAT stations in Europe and Asia, results were obtained according to which the data transfer rate in the NAVDAT system is hundreds of times higher than in existing networks. By December 2023, experiments are ongoing to determine the data transfer rate and other characteristics of the new system. It is expected that in Russia a pilot zone for testing NAVDAT equipment will be deployed in 2024.

In recent years, the volume of transmitted information on safety at sea has grown significantly. The information obtained must be presented on electronic maps in real time. The existing narrowband data transmission systems from coastal stations to ships at a speed of 50 bps do not always meet modern requirements, - said Sergey Pomazunov, interim general director of the Neptune Research Institute.[1]
