+# 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](https://wiki.myriadrf.org/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
+```
