GPS test setup

Usage

# replaying a static location
./gpstest.sh -e <ephemeris file> -s <static location>

# replaying a prerecorded route (NMEA cvs file)
./gpstest.sh -e <ephemeris file> -d <dynamic location>

If -e is not provided the latest ephemeris file will be downloaded from https://cddis.nasa.gov/archive/gnss/data/daily/20xx/brdc/. (TODO: add auto downloader)

Hardware Setup

LimeSDR USB
Asus AX58BT antenna

Software Setup

https://github.com/myriadrf/LimeSuite To communicate with LimeSDR the LimeSuite is needed it abstracts the direct communication. It also contains examples for a quick start.

The latest stable version (22.09) does not have the corresponding firmware download available at https://downloads.myriadrf.org/project/limesuite. Therefore version 20.10 was chosen.

https://github.com/osqzss/LimeGPS Built on top of LimeSuite (libLimeSuite.so.20.10-1), generates the GPS signal.

./LimeGPS -e <ephemeris file> -l <location coordinates>

# Example
./LimeGPS -e /pathTo/brdc2660.22n -l 47.202028,15.740394,100
