VisibilitySegment.CalculateRefraction(TimeSpan, Variable) Method

Top

Description

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.

Method Signature

VisibilitySegment.CalculateRefraction(	TimeSpan epoch,
	Variable distance)

Arguments

epoch
Description:	The epoch at which to evaluate the refraction calculation.

distance
Description:	The refracted distance between the observer and the target summed along the path of the refracted ray.
Valid Range:	distance ≥ 0

Return Value

Type:

boolean

Returns true if calculating the refracting target was successful and false if no solution could be calculated.
