I am trying to analyse my raw GNSS data on the GNSS Analyser app from here https://github.com/google/gps-measurement-tools. The installation guide includes the following step:

4.2 gunzip installation The automatic ftp code inside GnssAnalysis will download ephemeris zip files, and attempt to unzip them using gunzip.

  • Download gzip.exe from here http://ftp.gnu.org/gnu/gzip/gzip-1.9.zip
  • Extract the files from the zip file, rename gzip.exe to gunzip.exe
  • Move gunzip.exe to somewhere in your Windows path (type path in the Windows Command Prompt to see what your path is, typically you will find a directory C:\Windows\system32 and you can put gunzip.exe there.)

However, upon downloading gunzip, I cant find a gzip.exe file, and hence tried renaming the gzip.c and gzip.h file instead. It did not work and I got this error when attempting to process my own raw data.

  • `gzip -d` should do the trick. `man gzip` should provide you with more features you might need for your particular task. – Lothar Mar 09 '19 at 16:32
  • Hi, would you be able to elaborate? I dont see any gzip -d file amongst the unzipped gunzip folder. Thank you and sorry if the question seems stupid, I am a beginner who needs this for my school project! – reddagger Mar 09 '19 at 17:17
  • `-d` is an option you pass to the command to tell it to `decompress`. There are many more options that are explained by calling `man gzip` – Lothar Mar 09 '19 at 18:33
