Description

VisibilitySegment.CalculateRefraction(Variable epoch, Array refractedPos)

Variable

Calculates the refracted ray from the observer to the target and returns the apparent refracted position of the target. The Earth uses the WGS 84 (World Geodetic System 1984) reference ellipsoid.

VisibilitySegment.CalculateRefraction(Variable epoch, Variable distance)

Variable

Calculates the refracted ray from the observer to the target and returns the refracted distance. The Earth uses the WGS 84 (World Geodetic System 1984) reference ellipsoid.

VisibilitySegment.CalculateRefraction(Variable epoch, Variable angle, Variable distance, Array refractedPos)

Variable

Calculates the refracted ray from the observer to the target and calculates the refracted elevation angle, refracted distance and apparent refracted position of the target. The elevation angle is calculated as the angle between the Observer-to-Target vector and the Observers's local horizontal plane, which is tangent to the central body's reference spheroid. The Earth uses the WGS 84 (World Geodetic System 1984) reference ellipsoid.
