TL;DR: The paper presents the status of the Galileo frequency and signal structure, status Sept. 2002 and new results on reciprocal GPS/Galileo signal degradation due to signal overlay are presented showing a minimum impact and confirming the high level of interoperability of the two systems.

TL;DR: In this paper, the authors present the final Galileo Signal Plan and analyze all the modulations of the final Signal Plan, including the MBOC modulation for the common signal modulation in the E1/L1 frequency.

TL;DR: A new method for tracking the pilot codes of the Alt-BOC is proposed, a method that is using the properties of the 2 code Alt- BOC, and using sub-carrier tracking techniques as described in [7] and [8].

TL;DR: The road to the signals Galileo has today as a baseline has been tedious and long, but has followed a logic from the start as mentioned in this paper, and the final touch to the Galileo signal plan was achieved in 2006 when the Working Group on GPS and Galileo Compatibility and Interoperability finally agreed upon the great interest in a new modulation for the E1/L1 frequency.

TL;DR: In this paper, the authors proposed a global system dedicated to radionavigation and radiopositioning and includes a land segment comprising: ~ a global network of ground beacons (RBS) emitting an upwards wide spectrum radioelectric signal to user satellites, ~ a mission and control center (CMC) which creates work plans for some user satellites and transmits them when they fly over the master beacons, a processing center (CT) that receives remote measures sorted by the CMC, separating remote measurements into remote measurements necessary for processing specific to the processing centre (CT
