Time and frequency transfer using EGNOS satellite system

Popis výsledku v původním jazyce

EGNOS (European Geostationary Navigation Overlay Service) is the European satellite navigation system which augments GPS and makes it suitable for safety critical applications. It is one of the Satellite Based Augmentation Systems (SBAS). It uses three geostationary satellites transmitting signals in the GPS L1 frequency channel These signals are almost identical to the GPS signal and thus can be used for time transfer in the same way. Since the geostationary satellites move slightly and very slowly towards the user, one can assume that some of the measurement errors (e.g. multipath, atmospheric delay) will also show small and slow variation compared to GPS measurements and better performance of the time and frequency transfer can be expected. We therefore performed an experimental measurement in order to verify that the fluctuations in measured delay of the received signal caused by multipath are really much slower compared with using GPS and the time transfer can be improved by using
