MelbourneWubbenaCombination (OREKIT 12.1.2 API)

java.lang.Object
- org.orekit.estimation.measurements.gnss.MelbourneWubbenaCombination

All Implemented Interfaces:

MeasurementCombination
```
public class MelbourneWubbenaCombination
extends Object
implements MeasurementCombination
```
Melbourne-Wübbena combination.
This combination allows, thanks to the wide-lane combination, a larger wavelength than each signal individually. Moreover, the measurement noise is reduced by the narrow-lane combination of code measurements.
```
    mMW =  ΦWL- RNL
    mMW =  λWL * NWL+ b + ε
 
```
With:
- mMW : Melbourne-Wübbena measurement.
- ΦWL : Wide-Lane phase measurement.
- RNL : Narrow-Lane code measurement.
- λWL : Wide-Lane wavelength.
- NWL : Wide-Lane ambiguity (Nf1 - Nf2).
- b : Satellite and receiver instrumental delays.
- ε : Measurement noise.
Narrow-Lane and Wide-Lane combinations shall be performed with the same pair of frequencies.
Since:

10.1
