How to read incomprehensible data output from USB port in Ubuntu?

Question

I have a GPS Receiever connected to my USB port. I wanted to see the RAW data to understand which protocols are used to make sense of the RAW data, but when I enter the command:

cat /dev/ttyUSB0 -> gps_data.txt

Into my terminal, I get incomprehensible data like in the picture below.

And so on. How do I make sense of this?

Update: I found out that I am trying to decode non txt data into txt format. So my new question is that how do I decode it into a human-comprehensible format? I think the protocol used here is NMEA 0183 but I don't know how to approach it on terminal.
