E1 acquisition and tracking of the first four Galileo IOV satellites in Korea

Galileo system is being under the in-orbit validation (IOV) and and its constellation consists of Proto Flight Model (PFM) and Flight Model 2 (FM2) launched in October 2011 and FM3 and FM4 launched in October 2012. The researchers of the NAVIS Centre and the European Space Agency (ESA) have announced the signal tracking of all the four satellites and the first determination of a ground location, respectively. This paper for the first time, presents E1 acquisition and tracking results using our own receiver after receiving the signals of all the four Galileo satellites at the same time, in Korea. The simulation results show that the SW based Galileo E1 receiver of ETRI successfully processes the signals of all the four Galileo satellites.
