OpticalLink.ComputeLinkMargin(Variable, Variable) Method

Top

Description

Returns the link margin in dB for the link based on the provided receiver sensitivity and model parameters provided in OpticalLink and its child objects Transmitter, Receiver, and AtmosphericLossParameters. For transmission through the atmosphere, this method computes the losses inclusive of precipitation effects (rain, snow) and atmospheric scattering. Any effect of scintillation may be accounted for separately with the help of the OpticalLink GetAtmosphericScintillationLinkDeficit and OpticalLink GetAtmosphereScintillationFadeProbability methods.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
