--rfsimulator.prop_delay 238.74
```
For simulation of a satellite in low earth orbit (LEO), two channel models have been added to rfsimulator:
- `SAT_LEO_TRANS`: transparent LEO satellite with gNB on ground
- `SAT_LEO_REGEN`: regenerative LEO satellite with gNB on board
Both channel models simulate the delay and Doppler for a circular orbit at 600 km height according to the Matlab function [dopplerShiftCircularOrbit](https://de.mathworks.com/help/satcom/ref/dopplershiftcircularorbit.html).
An example configuration to simulate a transparent LEO satellite with rfsimulator would be:
```
channelmod = {
max_chan=10;
modellist="modellist_rfsimu_1";
modellist_rfsimu_1 = (
{
model_name = "rfsimu_channel_enB0"
type = "SAT_LEO_TRANS";
noise_power_dB = -100;
},
{
model_name = "rfsimu_channel_ue0"
type = "SAT_LEO_TRANS";
noise_power_dB = -100;
}
);
};
```
This configuration is also provided in the file `targets/PROJECTS/GENERIC-NR-5GC/CONF/channelmod_rfsimu_LEO_satellite.conf`.
Additionally, rfsimulator has to be configured to apply the channel model.
This can be done by either providing this line in the conf file in section `rfsimulator`:
```
options = ("chanmod");
```
Or by providing this the the command line parameters:
```
--rfsimulator.options chanmod
```

### NR UE
At UE side, there are two main parameters to cope with the large NTN propagation delay, cellSpecificKoffset and ta-Common.
`cellSpecificKoffset` is the same as for gNB and can be provided to the UE via command line parameter `--ntn-koffset`.
`ta-Common` is a common timong advance and can be provided to the UE via command line parameter `--ntn-ta-common` in milliseconds.
`ta-Common` is a common timing advance and can be provided to the UE via command line parameter `--ntn-ta-common` in milliseconds.

```
For LEO satellites a third parameter specifying the NTN propagation delay drift has ben added, ta-CommonDrift.
`ta-CommonDrift` provides the drift rate of the common timing advance and can be provided to the UE via command line parameter `--ntn-ta-commondrift` in microseconds per second.
Also, to perform an autonomous TA update based on the DL drift, the boolean parameter `--autonomous-ta` should be added in case of a LEO satellite scenario.
