Hello everyone,

I have a recorded signal from GPS in .bin file which is stored in "int16" format. I want to convert the data into "int8" without losing the data.

I can't upload the file here for reference as it is too big (47 Gb).

For further clarification, I want the file to be replayed with a HackRF One connected directly to an ublox GNSS reciever via an SMA to SMA cable. I am currently studying GNSS interference monitoring and fully aware of what I am doing and all the risks of transmission in L-band therefore, I am conducting this experiment in a fully controlled situation.
