Presentation of the results of the scoping study on pseudolites requested by DG ENTR

CORSA presented to DG ENTR the results of a scoping study on pseudolites, which was agreed with them at the beginning of December 2010. DG ENTR is planning to launch an ITT or an FP7 project on pseudolites and requested a scoping study by JRC to define a clear focus and scope beforehand. During the meeting, a presentation was given summarising the various issues to address (e.g., selection of codes, selection of pulsing scheme, selection of frequency offset, compatibility and impact on other services and non-participating receivers) when considering the use of pseudolites in the different bands under consideration (i.e., L1, Galileo E6, ISM at 2.5 GHz and 5.8 GHz). The presentation was followed by a 2 hours discussion. During the discussion, both Ignacio Fernández and Dominic Hayes underlined that the results, extent and quality of the study were outstanding, particularly keeping in mind that it has been completed in less than six weeks. The report will serve ENTR as a reference document when launching the project on pseudolites this year. ENTR foresees the participation of the JRC playing two different roles: one following the progress of the project, and also organising the trials with the pseudolites in our laboratories. This will be formalised in the coming weeks. The discussion was very fruitful and we finally came to a decision as to what could be the focus of the project on pseudolites. We identified two frequency bands of interest: Galileo E6 and the ISM at 2.5 GHz. Galileo E6 is very interesting because it could become attractive to deploy innovative indoor and outdoor positioning services based on pseudolites with a very limited impact on non participating receivers.
