I have a GPS tracker with TK06a Chipset, and I have my own tcp listener, everything is working fine, I have received the data from the device with this format :

```
#355488020131775##1#0000#AUT#01#52500100232a47#10341.175280,E,121.322800,N,0.28,0.00#111113#171607.000##

```

I think i figured out what are these, (for example the first one is the IMEI), but I didn't know how to convert (10341.175280,E) and (121.322800,N) to something that google maps can understand.

beside the device has a poor user manual and no documentation for the protocol.

the real location should be in here (1.355269,103.686426) maybe this can lead you to solve this mystery :)

Thanks in advance.

**Edit:**

I Found this on the web, maybe some will find it useful : 

The decode of the line above.
