This work describes the design, implementation and validation of an autonomous gas leakage inspection robot. Navigation with centimeter level accuracy is achieved using RTK GNSS integrated using the ROS 2 and Nav2 frameworks. The proposed solution has been validated successfully in terms of navigation …

In this document we present information about a test that we made to test SPOT with the RTK-GNSS and ROS2.

RTK-GNSS (Real Time Kinematic - Global Navigation Satellite System) is based on a ‘rover’ GNSS antenna that receives error correction information from a ‘base’ GNSS antenna. While the rover can be placed on a robot to move around, the base station has the additional ‘knowledge’ of being stationary. …

Several studies have suggested that precision livestock farming (PLF) is a useful tool foranimal welfare management and assessment. Location, posture and movement of an individual are key elements in identifying the animal and recording its behaviour. Currently, multiple technologies are available for …

Voor een stage bij S[&]T moest een embedded systeem worden ontworpen dat GNSS storingssignalen kan detecteren. Het project dat voor de stage werd gedaan duurde 5 maanden. Gedurende deze 5 maanden werd een embedded systeem ontworpen. Dit ontworpen systeem werd uiteindelijk Mobile GNSS Interference Detection …

Het gebruik van Dynamic positioning (DP) wordt op veel schepen toegepast waaronder op het schip de Aegir van het bedrijf Heerema Marine Contractors. Het DP systeem heeft hierbij een initiële positie input nodig wat verkregen wordt via GNSS plaatsbepalingssystemen. Aan boord van de Aegir bevinden zich …

Autonomous driving in public roads requires precise localization within the range of few centimeters. Even the best localization systems based on GNSS cannot always reach this level of precision, especially in an urban environment, where the signal is disturbed by surrounding buildings and artifacts. …

Even the best current precise localization system based on the Global Navigation Satellite System (GNSS) can not always reach this level of precision, especially in an urban environment, where the signal …

Global Navigation Satellite Systems (GNSS) currently dominate the Positioning, Navigation and Timing (PNT) community and there are no signs that this will change in the near future. But for many years the weeknesses of GNSS have been well known and besides research into GNSS a lot of research into back …

Description of the evolution of navigation from a restricted field of application (nautical) and executed by a select group of navigators working in almost splendid isolation to a wide field of application (nautical, aeronautical, CRM) executed by groups of people sharing different knowledge and skills …
