Platform Orientation - adjacentlink/emane GitHub Wiki
The emulator physical layer accounts for the transmitting and receiving NEM’s platform orientation when determining the antenna gain based on antenna profiles.
EMANE Location Events are required when using antenna profiles and each event includes the following 3 elements for a given NEM:
- position - latitude, longitude, altitude (required)
- velocity - azimuth, elevation, magnitude (optional, defaults to 0)
- orientation - pitch, roll, yaw (optional, defaults to 0)
The position element identifies the platform’s location and not the antenna location, as a given platform may have more than one antenna. In cases where a platform has multiple antenna and their location on the platform needs to be accounted for, the <placement> element within the antenna manifest is utilized to define the offset of each antenna relative to the platform’s position. The velocity element identifies the speed and direction of the platform relative to true north.
Orientation defines the pitch, roll and yaw angles (Euler angels) about the platform’s latitudinal, longitudinal and vertical axes respectively. Yaw and pitch are defined relative to the velocity vector’s azimuth and elevation components respectively and roll is defined relative to wings level position.
The arrow directions indicate positive angles.
