Package org.orekit.estimation.measurements.gnss

This package provides methods to handle GNSS measurements.

The two main types of GNSS measurements are code and carrier phase measurements. This package provides several methods to handle these two types of measurements (e.g. combination of measurement, phase ambiguity resolution, modeling of wind-up effect, etc.).
