TL;DR: The Galileo High Accuracy Reference Algorithm for SL1 and User Terminal (HAUT) project was awarded by the European Union Agency for the Space Programme (EUSPA) to Spaceopal GmbH and its partners ANavS, DLR IKN, IABG mbH and Iguassu Software Systems as discussed by the authors .
Abstract: The Galileo High Accuracy Service (HAS) will provide free of charge high accuracy corrections aiming to achieve Precise Point Positioning (PPP) in real time through the Galileo signal (E6-B) and by terrestrial means (Internet). The HAS will comprise two services levels; Service Level 1 (SL1) with global coverage providing high accuracy corrections (orbits, clocks) and biases (code and phase) for Galileo E1/E5b/E5a/E6 and E5AltBOC and GPS L1/L5/L2 signals. Service Level 2 (SL2) with regional coverage providing SL1 corrections plus atmospheric (at least ionospheric) corrections and potential additional biases. Within this context, the Galileo High Accuracy Reference Algorithm for SL1 and User Terminal (HAUT) project was awarded by the European Union Agency for the Space Programme (EUSPA) to Spaceopal GmbH and its partners ANavS GmbH, DLR IKN, IABG mbH and Iguassu Software Systems. In April 2022 and only after one-year development, the project achieved its Acceptance Review and delivered a Galileo HAS User Terminal capable to work with corrections from the Galileo HAS signal (E6-B) and terrestrial means. In this article, highlights on the User Algorithm and User Terminal are presented. Performance results using corrections and products generated by the Galileo HAS infrastructure and IGS are introduced.

TL;DR: A Real-Time Kinematic positioning of UAVs with Global Navigation Satellite System (GNSS) signals is performed and the accuracy with a laser tracker that provides ranging measurements with a precision of up to 16μm is assessed.
Abstract: Near-field antenna measurements can be efficiently performed with Unmanned Aerial Vehicles (UAVs). An accurate knowledge of the position of the UAV is needed for determination of the 3D antenna pattern. In this paper, we perform a Real-Time Kinematic (RTK) positioning of UAVs with Global Navigation Satellite System (GNSS) signals and assess the accuracy with a laser tracker that provides ranging measurements with a precision of up to 16μm. The measurement results show that the positioning solutions of the GNSS RTK system and of the Laser tracker agree within a few centimeters. This accuracy is also correctly indicated by the self-assessment of the RTK system.
