# GPS test setup
Testing the GPS receiver using GPS spoofing. At the moment only
static location relpay is supported.
# Usage
on C3 run `rpc_server.py` , on host PC run `fuzzy_testing.py`
`simulate_gps_signal.py` downloads the latest ephemeris file 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
```
