# 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/.

# 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
|
||
|
```
