package org.orekit.estimation.measurements
The measurements package defines everything that is related to orbit
determination measurements.
All measurements must implement the
ObservedMeasurement interface, which is the
public API that the engine will use to deal with all measurements. The
estimated theoretical values can be modified by registering one or several EstimationModifier objects. These
objects will manage notions like tropospheric delays, biases, stations offsets ...- Since:
