Package org.orekit.estimation.measurements.filtering

This package provides measurement pre-processing filters.

Measurement pre-processing filters are used to exclude measurements before they are used during an orbit determination process. Example of pre-processing filters are:

• Minimum satellite elevation
• Minimum signal to noise ratio
• ...
