Description
The AltitudeRef command allows you to set the altitude reference for a vehicle.
This command is only valid for Great Arc vehicles.
The following table describes {AltRefOption} and <Parameters>:
| {AltRefOption} | <Parameters> | Description |
|---|---|---|
| Ref | MSL | Set the altitude reference to mean sea level. |
| Terrain | Set the altitude reference to the terrain. | |
| WGS84 | Set the altitude reference to the central body's reference ellipsoid. | |
| TerrainGran | <GranValue> | The Granularity value which is a real number between 1.0m and 600000m, entered in Connect distance units.
The smaller the granularity value, the longer it will take to process the vehicle. |
| InterpMethod | EllipsoidHeight | Interpolate using the greatArc interpolator without considering terrain at all. (This is the default method.) |
| TerrainHeight | Assigns a height above terrain by a linear interpolation between the heights above terrain at the waypoints. | |
| OnTerrain | Assumes that the waypoints are on the terrain (0.0 height) and the interpolated points should also be on terrain. |
Examples
To set the altitude reference for Aircraft1 to mean sea level:
AltitudeRef */Aircraft/Aircraft1 Ref MSL
To set the altitude reference for Aircraft1 to terrain level and set the terrain sampling rate to 10 km:
AltitudeRef */Aircraft/Aircraft1 TerrainGran 10000
To set the altitude reference interpolation method for Aircraft1 to "on terrain":
AltitudeRef */Aircraft/Aircraft1 InterpMethod OnTerrain
To set the altitude reference for Aircraft1 to Terrain, and the granularity to 7.75 km
AltitudeRef */Aircraft/Aircraft1 Ref Terrain TerrainGran 7750.0
