Azimuth and Elevation observation.

Represents an angular observation in the local horizontal coordinate system:

• Azimuth (Az): Angle measured clockwise from true North, in radians [0, 2π)
• Elevation (El): Angle measured above the local horizon, in radians [-π/2, +π/2]

Fields

epoch: DateTime<Utc>

UTC epoch of the observation

azimuth: f64

Azimuth in radians [0, 2π), measured clockwise from North

elevation: f64

Elevation in radians [-π/2, +π/2], measured above horizon

range: Option<f64>

Slant range in kilometers (optional)

range_rate: Option<f64>

Range rate in km/s (optional)

azimuth_rate: Option<f64>

Azimuth rate in rad/s (optional)

elevation_rate: Option<f64>

Elevation rate in rad/s (optional)
