Introduction of the Research Group
BME Satellite Positioning and Navigation Lab (BME SatNav Lab) is a research group of the Budapest University of Technology and Economics at the Department of Geodesy and Surveying of the Faculty of Civil Engineering. The laboratory aims to do cutting-edge R&D activities in the whole spectrum of satellite positioning and navigation, with a special focus on highly accurate GNSS (Global Navigation Satellite Systems) positioning and their applications as well as the quality assurance of satellite positioning including the study and development of safety-of-life (SoL) applications of GNSS. The BME SatNav Lab's main research fields are: - Application of GNSS observations for monitoring various environmental parameters including atmospheric water vapor, space weather/ionospheric activities/crustal deformations; - Quality control and integrity monitoring of GBAS (ground based augmentation systems) and SBAS (satellite based augmentation systems); - Safety-of-life applications of GNSS: positioning and navigation of aircraft, autonomous vehicles; - Sensor fusion of GNSS receiver with other positioning sensors (inertial, image based, etc.) - Application of GNSS positioning in land and engineering surveying, structural health and deformation monitoring and in early warning systems; - Establishment and maintenance of permanent GNSS stations for providing GBAS corrections and/or monitoring GNSS positioning services; - Methodology development of highly accurate and reliable GNSS positioning with a special emphasis on the mitigation of systematic error sources, such as atmospheric effects, antenna phase center models as well as signal interference.
Achievements
- Establishment and maintenance of ground GNSS infrastructure for correction services and quality monitoring: the lab operates 3 EUREF EPN GNSS stations and an 11-station integrity monitoring network for the Hungarian Air Navigation Service Provider.- Application of GNSS for a wide variety of engineering applications, such as deformation monitoring in the vicinity of a nuclear power plant to assess geohazards, construction control of bridges, early warning systems, atmospheric water vapor monitoring;
- Methodological development of the integrity modeling of GNSS positioning in the field of atmospheric effects: the lab developed an algorithm for assessing the maximum residual error of signal delays caused by the neutral atmosphere that helps to assess the integrity of the positioning service;
- Methodological developments in the sensor fusion of low-cost GNSS and inertial sensors for autonomous vehicles together with the colleagues of the Institute for Computer Science and Control of the Eötvös Lorand Research Network;
