I have tablet - Dell latitude 10, running Windows 8, with integrated Broadcom GNSS Receiver BCM47511 (GPS,Glonass...). Because it is integrated GPS and Windows 8, there is the "new" way of providing GPS data called Windows Location Provider. This "new" way means it doesn't work properly or at all in almost any navigation/localisation software at this moment - because this software expect GPS data coming from COM port. Including QGIS - at this moment it is on the road map - http://hub.qgis.org/issues/7878
Anyway after extensive search I found software which can bypass MS localisation platform. It is called Centrafuse Localizer. This software can simulate COM port and send through it GPS data so some software is able to read it.
Unfortunately not QGIS. QGIS can see the port (just to test it I changed COM 1 to 5 and 7) and it changes Serial device list in QGIS but after hitting Connect it always fails.
If you are thinking about tablet with integrated GPS think twice! From my point of view it is just too early - probably also no proper drivers yet as what I have read from Broadcom Readme file. Even when GPS "works" the refresh rate and precision is terrible comparing to my phone. And all software must be changed to work with this new interface...
Is there other way I could try to make work tablet integrated GNSS (GPS) on Windows 8 with QGIS?
