Hi All
I have finished all the routines in my Land Surveying Program for a Level and Total Station. Now I am busy with interfacing the GPS for NTRIP firstly.
The problem that I have is that in VB.net I used the SIM Card in the GPS to access NTRIP, which was a mission when you wanted to check your Data Balance as one had to put the SIM Card in a phone to check it.
What I want to do in the Android version is to have the SIM in your phone and access NTRIP.
Here is my VB.net compact code to get all the Mount Points:

What would be nice if the Surveyor gets a display of how far away these Mount Points are from his\hers position.
A kick (not too hard please!!) in the right direction will be appreciated.
