It's been a while (i.e., years) since I've looked at this, but the last time I researched this the Bluetooth Serial Port Profile (SPP) was your best option. If there isn't any explicit documentation for an interface, you basically have to hope that the receiver outputs its data via the Bluetooth SPP, and that your Android device supports SPP. There are ...
If I were you, I'd throw away the PDF form. I doubt you'll get it working with GPS coordinates getting in there, unless you copy paste them in. What you might like to look into is the following two products, both of which support offline data collection with nice forms: Open Data Kit, a free Android only tool with a web-based backend and Google Fusion ...
@Martin has provided excellent links in order to create plugins for QGIS. To make life a little easier, there is a plugin called Plugin Builder which very easily creates all the core files you need for your plugin. You can download and install this from the QGIS toolbar: There is also a tutorial here which describes how to use the Plugin Builder ...
I recommend you to read the qgis cookbook: http://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/ There you can read how to program a plugin that suits your needs. In the section plugins: http://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/plugins.html it is shown how to set up a plugin with a user interface that is using qt
here is my simple approach: create a new map in umap: http://umap.openstreetmap.fr/en click Import Data a select all the gpx files you have and upload them into map (you can import all of them at once) enter Edit map settings > Default properties, choose opacity 0.25, weight 10. The three steps above will take 5 minutes and here is the result:

In the link i have give you, it is stated, that Mapbox have a similar service ...
Is the GNSS receiver providing NMEA data? If so, is the GSV sentence provided? If so, the elevation in degrees is provided in that specific sentence. http://aprs.gids.nl/nmea/#gsv
You can try GpsGate to relay GPS input over a virtual COM port with selectable baud rate. The GpsGate Express Client is free of charge. It works for me with a Garmin device connected via USB inside QGIS.
Converting geographic (latitude-longitude) coordinates to plane (X-Y or row-column) coordinates is a matter of map projection. Your main constraint is probably the projection which is already being used to map the other features (runways, terminals, etc). That is, if they are already recorded/stored/displayed in some flat X-Y system, then you need to ...
Do you mean something similar to a CORS network? If so IGS has a few stations in India: http://igscb.jpl.nasa.gov/network/complete.html I am looking for GNSS receivers active in India as well, hopefully a more dense network of receivers. If anyone knows of such a service please respond. I would guess that there are GAGAN stations with some information ...
