Sample log files to run with GnssAnalysisApp
These zip files have GnssLogger log files with ephemeris for you to process with the GnssAnalysisApp
driving (log file, driving, GPS, L1L5, with truth nmea)
ionotropodemo (two log files, GNSS and GPS-only, stationary with true position in readme.txt)
GnssAnalysisApp, desktop app, download zip file with executable:
New: v2.6.3.0 of GnssAnalysisApp: Release notes and download links for GnssLogger apk for phones, and GnssAnalysisApp for desktops :
GnssAnalysisApp will download ephemeris zip files, and attempt to unzip them using gunzip in Windows.
Get gzip.exe from here www.gzip.org/gzip124xN.zip
Extract the files, 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.)

For Matlab code for processing GPS measurements see the opensource folder in the GPS Measurement Tools repository on GitHub.
