Maritime Safety Services over a Shared VDE-SAT Network

About the project

Together with Space Norway, we are working on developing maritime IoT services based on the AIS 2.0 technology (also known as VDES), and maritime distress alert detection. This new, ESA-funded research project will also study and develop a roaming capability between satellite networks of two different operators which will speed up the time before global real-time VDES coverage is available for digital services and the customers.

Service Description

1. IoT-type preventive monitoring:

IoT-type maritime service for preventive monitoring of vessel onboard machinery (ship engines, boilers, etc.). The equipment and systems installed in ships are becoming more and more complex and the demand for monitoring is on the rise. While at sea, a ship’s need for maintenance or spare parts can be identified, making maintenance and repairs easier and time efficient when in port. Additionally, due to new requirements from IMO, there is an increased need for documentation of exhaust emissions from ships, especially when sailing in sensitive regions.

2. DSC distress monitoring:

Maritime monitoring/distress signal collection is a key activity of maritime authorities. VHF-based DSC distress messages from ships is one of the recommended means for initiating Search-and-Rescue (SAR) operations under the IMO SOLAS convention. This service will have a strong advantage in remote (Arctic) waters, resulting in an increased chance of observing ships in distress faster with a potential for saving lives.



The presented services require frequent connectivity, which is a challenge in the early phase of any LEO (Low-Earth Orbit) satellite network. Teaming up with Space Norway results in growing network capabilities that help to ensure high service quality much earlier than with single networks. It is achieved by increasing the daily amount of satellite passes and data transmissions. For both services, our Sternula-1 satellite and Space NorwayNorSat-2 (worlds first VDES capable satellite) will be used.

Current Status

The project was kicked off in November 2022.
