These 6 folders are supplementary materials for the paper entitled
E.T. Medina and E.S. Lohan, "GNSS spoofing modeling and consistency-checks-based spoofing mitigation  with Android raw data" and submitted to MDPI Remote Sensing, Jan 2025 and they contain  GNSSlogger traces collected by Authors with Android devices. It is to be noted that no known spoofers are present in this data (except perhaps in the FLIGHT folder), and that the spoofing modelling based on this data can be found in the above-mentioned paper.


These datasets can be cited as
E.T. Medina and E.S. Lohan, "GNSSLogger traces for multi-modal transportation studies: car, walk, ferry, plane, bus, and bike", open-access datasets,  10.5281/zenodo.14712684


Each of the six folders  contain at least the followings:

 - the *nmea, *txt and *23o/*24o files as recorded by GNSSlogger app and corresponding to NMEA tracks, full sensor data and RINEX observation files
- the *kml map of the measured track (for  Google Earth plotting) generated based on *nmea files


The name of the folders are matching the environments where each measurement was taken and are explained in the paper of E.T. Medina and E.S. Lohan, "GNSS spoofing modeling and consistency-checks-based spoofing mitigation  with Android raw data"

In each folder there might be few additional pictures taken from the measurement environment. The  Ferry and Car folders also contain the precise ephemeris *sp3 and  broadcast ephemeris (BE) *rnx files  corresponding to the day of measurements.

For the other folders, the *sp3 files are available in open access, for example  at ftp://ftp.gfz-potsdam.de/GNSS/products/mgex/  and the  BE *rnx  files can be downloaded for example from https://igs.bkg.bund.de/root_ftp/IGS/BRDC/
The GPS DOY and WOY can be found for example at https://www.ngs.noaa.gov/CORS/Gpscal.shtml
