Klappentext zu „Tappero, F: Remote Synchronization Method for the Quasi-Zeni “
This book presents a novel satellite timekeepingsystem which does not require on-board atomic clocksas used by existing navigation satellite systems suchas GPS, GLONASS or the GALILEO system. Thisconcept is differentiated by the employment of asynchronization framework combined with lightweightsteerable on-board clocks which act as transpondersre-broadcasting the precise time remotely provided bythe time synchronization network located on theground. This allows the system to operate optimallywhen satellites are in direct contact with the groundstation, making it suitable for a system like theJapanese Quasi-Zenith Satellite System, QZSS. Lowsatellite mass and low satellite manufacturing andlaunch cost are significant advantages of this novelsystem. Two possible implementations of the timesynchronization network for QZSS are presented.Additionally, the problem of satellite communicationinterruption is analysed and a solution is presented.Finally a positioning and timing quality analysis,aimed to provide understanding of the actual timingquality requirements for QZSS, is presented.
Autoren-Porträt von Fabrizio Tappero
Dr. Tappero holds a MS in electrical engineering and a PhD inengineering from UNSW, Australia. Dr. Tappero worked at the SpaceTechnology Group of AIST in Tsukuba, Japan on a novel timekeepingsystem for the QZSS. Presently, Dr. Tappero works as researcherat EPFL, Switzerland on GNSS synchronization algorithms andindoor positioning systems.
