Decoding GPS data - I do not know what the format is.

I have a GPS tracker that my friend lent. This is a Chinese model with sparse documentation. He got the built-in gps and gprs (sim) module, and he sent me his data to a specific IP address.

I can’t understand what all the numbers mean. I got latitude and longitude thanks to N and E. But the rest I'm not sure.

Here is an excerpt from my journal:

Note: the exact line from the tracker is stored in parentheses (...) I gave dates and times, because they can help decode the data if the tracker reports UTC time or something like that. I did not see anything suitable time signature, although
