Decrypt a binary packet of data

We have a Binary packet of data which captured from a car navigation head unit through local host UDP socket & 29000 port;

We know that this data includes some details about the navigation module (Trimble 66300 GPS module) like location, UTC time, speed, Heading…;

Now we want to decode the data structure and know how to read mentioned variable from incoming data;

Some sample data are attached and you can try to do;

System spec:

Hyundai Tucson 2013 Head unit

OS: WinCE 6

Data sender: [url removed, login to view] through network Local host “” Port :29000 and UDP


GPS : Trimble 66300

Skills: Algorithm, C Programming, Matlab and Mathematica, Python

I can get a byte array in that packet then show it to ASCII (UTF8, UTF16) to you diagnose that data. I can not know struct of data in that packet.
