Integrity Concept for Maritime Autonomous Surface Ships’ Position Sensors

Galileo Integrity Concept and its Applications to the Maritime Sector

Galileo is the European Global Navigation Satellite System, under civilian control. Galileo will provide their users with highly accurate global positioning services and their associated integrity information. The main objective of this article is to explain the basis of the Galileo integrity concept, which is fundamental for safety-critical applications such as maritime navigation. A review of...

Active Online Calibration of Multiple Sensors for Autonomous Surface Vessels

We present an approach to actively calibrate the exteroceptive sensors of an Autonomous Surface Vessel (ASV) autonomously. The approach consists of locating suitable calibration sites in the environment from aerial imagery, navigating to them, gathering calibration data and estimating the required parameters from data. We have conducted experiments using an ASV in a lake to validate our approach.

Low - power concepts for autonomous maritime systems

Autonomous working systems are used in maritime research in different fields of application already for decades. Often it is not possible to keep a permanent connection with a cable. This stems from the depth of missions up to 6000 meters, difficult reachable locations or mission periods of several months. Generally, the power supply of such systems can be guaranteed with accumulators only. Alt...

Integrity--an outmoded concept?

We’ve heard a lot in the news recently about “integrity,” or the lack thereof. Although the word has been used most often in politics, it has surfaced in business, medicine, law and even in relation to the United States site for the Winter Olympics. I’ve pondered what this word really means. It is associated with images of “honesty,” “a handshake is as good as my bond,” “keeping promises,” “hon...
