Struct Aer

pub struct Aer<AngularMeasure = Degrees> {
    pub azimuth: AngularMeasure,
    pub elevation: AngularMeasure,
    pub range: Meters,
}

Aer represents an Azimuth, Elevation, and Range measurement.

Azimuth/Elevation (or Az/El) is a common way of locating objects measured at a specific location on Earth in the local tangent plane (for instance, from a RADAR). That reference location is not included in the Aer struct, so re-contextualizing this requires knowing the point at which the observation was taken from or was in reference to.

An Aer can be passed an “AngularMeasure” generic argument, which means, for all practical purposes, either Degrees or Radians. The default is Degrees, but can be overriden by passing Radians into the Aer. Degrees tend to be a lot easier to use as an API and for humans, but when passing data between third party code and this library, you may find it’s less work to skip conversions through Degrees when reading or writing Aer data. If you don’t have some overriding conviction, using Degrees is a good idea.

Fields

azimuth: AngularMeasure

Angle in azimuth (left and right) in relation to some fixed point and orientation.

elevation: AngularMeasure

Angle in elevation (up and down) in relation to some fixed point and orientation.

range: Meters

Range to some point in space along the defined azimuth and elevation, in Meters.

Implementations

impl<AngularMeasure> Aer<AngularMeasure>

where Enu: From<Aer<AngularMeasure>>, Self: Copy,

pub fn to_lle<CoordinateSystem, LleAngularMeasure>( &self, obs: &Lle<CoordinateSystem, LleAngularMeasure>, ) -> Lle<CoordinateSystem, LleAngularMeasure>

where Radians: From<LleAngularMeasure> + Copy, LleAngularMeasure: From<Radians> + Copy, CoordinateSystem: CoordinateSystem<LleAngularMeasure>,

Take some observation (self), and contextualize it into some absolute Lle given some reference point obs that this Aer is in reference to.
