转换从GPS跟踪器接收的Lat和Long值

Question

I have created an application that will listen to a particular port in which a GPS tracker will send data to it.

There's not much support received from the company(Chinese) whom I bought the GPS tracker, for development purpose. So it's kind of tougher to grasp everything myself.

I was able to figure out most of the data that was sent from the GPS tracker. The only thing is, the location coordinates sent from the tracker is in some specific format which I think it needs to be converted.

It's something like this:

1234N07700
7689E000

(the above values are just sample)

So am having trouble in converting it to actual Lat & Long values. I tried searching in Google, but couldn't find any examples based on this. Maybe my search terms where wrong!

Atleast if the name of the format used to represent this coordinates is known, I would be able to do further research.

Any ideas? Thank you.

Example of a full string received from the gps tracker:

Check this website: http://www.sunearthtools.com/dp/tools/conversion.php

You will be able to see this format:

GPS: ddmm.mmmm[N,S]ddmm.mmmm[E,W] (Dec Min)

So I guess the location coordinate values starts right after the A in your screenshot and all the way till the E.

Based on your screenshot, the location would be 0829.1234N07700.5678E

Now for the latitude calculation part,

Consider 0829.1234N,
Take first two digits, and then divide the rest of the digits by 60 and add them together.
ie, Latitude = 08 + 29.1234/60 = 8.48539

If the last character was S instead of N, put negative sign to the result.

Now for the longitude calculation part,

Consider 07700.5678E,
Take first three digits, and then divide the rest of the digits by 60 and add them together.
ie, Longitude = 077 + 00.5678/60 = 77.009463

If the last character was W instead of E, put negative sign to the result.
