Ublox Software Write some Debug Information into the File.

Are anyone interested in the other Recordings?  :-//

Does anyone here have experience with GPS Data Analyse?

I recall it was possible to download the data from the GPS60 into various different formats and also possible to import the data into Google Earth and show the individual points on Google Earth and export the file as a KML file. In Google Earth the data was shown on the map as a selection of continuous dots were the GPS data was recorded on the route and these could be manipulated as you require. I don't recall there being any need to convert the file into any other format, but it was 10 or more years ago when I worked on this and I have forgotten much of the inner detail.

At work we only ever used Google Earth and I think a program called MapSource to check the route against the map. The important data for work purposes was data required the GPS data alongside GSM signal strength and GSM quality data for propagation prediction purposes, so a HP iPaq was used to interface with a Ericsson GSM transceiver and the GPS60 to produce the data file we needed.

You can buy external antenna which can be mounted internally on a car window, so it might be worth looking at one of these antenna and mount the antenna using suction cups to the train window.

Whatever method you decide to use, the file result will be a file with individual timing/locations points were the GPS unit has recorded Time, Date, Latitude, Longitude and Altitude.

That's a pretty sad statement of affairs.  Is it really that bad?

Not that bad as in Italy, Spain. It depent on the Date and Time and the Railway Station. Onboard the 1Class is quite safe.  :popcorn:
Thanks you Mrs. Merkel.  :palm:

I on the most Trains I tried to get a good Signal just the Railjet failed totally.
After some Minutes without a Signal the Receiver or the Software drive insane and I get no signal anymore.

I'm increasingly glad we have a moat.

GPSBabel is the way to go for GPS log file conversion on all sorts of computers. http://www.gpsbabel.org/

GPSBabel is FOSS and doesnt connect up to anything external.

Many GPS data loggers log in the GPX data format. Thats likely the best all around format for that kind of thing.

GPSBabel can turn your track logs into KML files that can be imported into Google Earth.
