GPS - Reuests from GPS Ensor in a Webbrowser (virtual Com Port or Mobile GPS Sensors )

Hello developer, I am looking for a programmer who can build with an interface that can pinpoint my GPS position in a web browser. Or rather, I need a script (Java) that is able to read the exact GPS coordinates. This does not mean triangulation via the internet! I need a script that can read these coordinates from a COM interface (GPS mouse) or directly from a smartphone or tablet. In my case I would like to read a vehicle position. The function should work in any standard web browser and also have setting options, whether you want to read the GPS sensor on a pad (Android / IOS) or a COM interface of a driver for GPS Mouse. As a rule, NMEA data are returned here. The script should be switched on and off as a function via the web browser. Dear developer - no offers, if you have no GPS experience or have to see if you can do it. So you should have a fair idea of ​​what I'm talking about here. No offers or requests like "I'll do in 14 days" or "I'll do the job, but you have to tell me what to do" ... You should have geared up with GPS and interfaces before. I do not want a Google query, which is created by triangulation - that brings me nothing - it must be queried 100% from the GPS sensor. Where Windows browsers & queries over COM ports are most important to me. I look forward to your offers.
