|
|
# Usage
|
|
|
|
|
```
|
|
|
|
|
# on host, start gps signal simulation
|
|
|
|
|
./run_static_lime.py
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
`run_static_lime.py` downloads the latest ephemeris file from
|
|
|
|

# 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.

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
