Receive a GPS Signal onboard a Train?

(1/9) > >>

Lord of nothing:
Hi
The problem is very simple. I need to receive the GPS Signal and draw my own Map.
The Main Railway Track Operator refuse to give me the GPS Information of his Tracks.  :--  |O
That mean I have to collect it my own. The problem on the new Cars who have Windows who have a Metal Coating on. My ordinary USB GPS Receiver dont work.

My old Receiver is an U-Blox who work with the Software perfect. I like there Software who work Stable up to 12h and more.

How about that: http://www.navilock.de/produkte/1299_u-blox-NEO-M8U/62756/merkmale.html?setLanguage=en
Is there a chance that the work better?
I think the Austrian Railway dont give me any Datasheet from the Windows Manufacture to see what kind of Metal the use.

Active Antenna?

or try and extract the detail from OpenStreetMap?

cdev:
Skytraq sell very sensitive and accurate receivers. In some ways, even more so than ublox.

Multi-constellation, multi frequency systems are coming to all GPSs soon which will work on a much wider range of frequencies and be inherently accurate to only centimeters without needing RTK. Even inside buildings or possibly even inside of some train tunnels. This is so people can be located in emergencies.

Did you receive any signal at all through the coating?

voltsandjolts:
Buy a GPS logger with magnetic or sucker mount - stick it on the outside of the train car before you get on!

Edit: This was just a joke, hence the exclamation mark. This would actually be a dumb thing to do.

With my "old" GPS Receiver no i dont think so.
I will make a Test the next time when I board the Train it will be next week.

Do the have a Software who I can "Control" there Receiver and Record the GPS Track?

Good idea but the most "Pc/ Laptop" Style GPS Receiver dont have an Antenna Port. The next problem how to power the Antenna? The "old" Trains have no Powersocket.

The Data get often from Images not from a Real GPS Position. I would like use the information in the future for my Big Data project.
For example if the Train dont Stop at the Station A1, A2, A3 and Stop on A4 it have to be a Fast Train.
The same think for Statistic Data. If the Train is at Time X on Point the need at least Time Y to get to Station A5...
But something like this need Time to find a solution for.

So for what kind of Freq are you talking about? Sat Based Nav. like GPS, Glonas, Baidu or Cell Phone, Wifi Based?

The Chassy is Aluminium.  ;D

Can you recommend some with
