How to convert my binary (hex) data to latitude and longitude?

Question

I have some binary data stream which passes geo location coordinates - latitude and longitude. I need to find the method they are encoded.

4adac812 = 74°26.2         


        

Answer 1

Brainstorming here.

If we look at the lower 6 bits of the second byte (data[1]&0x3f) we get the "minutes" value for most of the examples.

0xda & 0x3f = 0x1a = 26; // ok
0x60 & 0x3f = 0; // ok
0xe8 & 0x3f = 0x28 = 40; // ok
0x3c & 0x3f = 0x3c = 60; // should be 56
0xfd & 0x3f = 0x3d = 61; // should be 59

Perhaps this is the right direction?
