I ordered a gps module online called SiRFstarIIeLP with a simple uart connection. It says that the default is 9600 baud, but the data collected from a terminal roughly every second looks like it could be something at 9600 or 4800 baud.
I'm aware that this module can be communicated with using NMEA and sirf binary protocol, but the data I get seems corrupt as I can't even find any start or stop delimiters or anything for either protocol at any baud. Below is some data taken at 4800 then 9600 baud respectively in ascii characters.
4800 baud

I currently have the device on my window ledge and part of me thinks it may be not communicating with the satellite. But in that case the module should be sending messages out in the correct protocol anyway.
Also, I attached a text that was emailed to me from the supplier (ebay), that is obviously written by someone foreign. It may shed light If I could understand half of it. I have found from it that the module has a battery that charges up when power is connected and that is working properly along with a red lit led on the module.
Long post I know, but thanks to anyone who can help.
