FFGroundObservationFile.UseMeasurementWeighting Property

Top 

Description

A flag indicating whether or not to perform measurement weighting using internal geometric-based expressions. Measurement weighting should be turned off if a custom Measurement Noise model is implemented at the script level.

 

Measurement weighting will introduce higher noise values for measurements with lower elevation, and lower noise values for measurements with higher elevation, because measurements lower to the horizon will pass through more of the atmosphere and therefore will be noisier than measurements at higher elevation. The user-specified measurement noise values are used as the minimum noise values, and a geometric scale factor based on elevation is applied to increase noise as appropriate. This additional factor is only applied when processing measurements, not when simulating.
