Working Paper: Processing Options for the E6B Signals
With the rethinking of the Galileo Commercial Service (CS), the E6B signal will disseminate Precise Point Positioning (PPP) corrections whereas the E6C component will be encrypted for authentication purposes. Different processing options for the E6 signals are investigated and it is shown that the sensitivity gap between data and pilot processing can be bridged by introducing non-coherent integrations and inter-frequency aiding. Extended integrations mitigate the impact of noise while inter-frequency aiding reduces the dynamics perceived by the E6B tracking loop.
