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 ...
