Abstract
In order to monitor and manage vessels in channels effectively, identification and tracking are very necessary.

This work developed a maritime unmanned aerial vehicle (Mar-UAV) system equipped with a high-resolution camera and an Automatic Identification System (AIS).

A multi-feature and multi-level matching algorithm using the spatiotemporal characteristics of aerial images and AIS information was proposed to detect and identify field vessels.

The technology group Wärtsilä has successfully completed the installation and operational staff training for its Vessel Traffic Service (VTS) solution in the ports of Lisbon and Setúbal / Sesimbra in Portugal. The systems will increase the efficiency of these ports by reducing waiting time for vessels and allowing just-in-time pilotage. The state-of-the-art solution has been developed and supplied by Transas, a Wärtsilä company. The project was booked in July 2018 and completed in January 2019.

Morse Code – Forerunner of Digital Communication

 


Morse Code – Forerunner of Digital Communication

Very few people will recognise these devices and technology today.

Beginning in 1836, the American artist Samuel F. B. Morse, the American physicist Joseph Henry, and Alfred Vail developed an electrical telegraph system. This system sent pulses of electric current along wires which controlled an electromagnet that was located at the receiving end of the telegraph system.
