ClockCorrectionsProvider (OREKIT 12.1.2 API)

java.lang.Object
- org.orekit.propagation.analytical.gnss.ClockCorrectionsProvider

All Implemented Interfaces:

AdditionalStateProvider
```
public class ClockCorrectionsProvider
extends Object
implements AdditionalStateProvider
```
Provider for clock corrections as additional states.
The value of this additional state is a three elements array containing
- at index 0, the polynomial satellite clock model Δtₛₐₜ = a₀ + a₁ (t - toc) + a₂ (t - toc)²
- at index 1 the relativistic clock correction due to eccentricity
- at index 2 the estimated group delay differential TGD for L1-L2 correction
Since Orekit 10.3 the relativistic clock correction can be used as an EstimationModifier in orbit determination applications to take into consideration this effect in measurement modeling.
Since:

9.3

```
public ClockCorrectionsProvider(GNSSClockElements gnssClk)
```
    Simple constructor.
    
    Parameters:
    
    gnssClk - GNSS clock elements
- Method Detail
  - getName
```
public String getName()
```
    Get the name of the additional state.
    If a provider just modifies one of the basic elements (orbit, attitude or mass) without adding any new state, it should return the empty string as its name.
    
    Specified by:
    
    getName in interface AdditionalStateProvider
    
    Returns:
    
    name of the additional state (names containing "orekit" with any case are reserved for the library internal use)
  - getAdditionalState
```
public double[] getAdditionalState(SpacecraftState state)
```
    Get the additional state.
    
    Specified by:
    
    getAdditionalState in interface AdditionalStateProvider
    
    Parameters:
    
    state - spacecraft state to which additional state should correspond
    
    Returns:
    
    additional state corresponding to spacecraft state
