Package org.orekit.propagation.analytical.gnss

Class FieldClockCorrectionsProvider<T extends CalculusFieldElement<T>>

java.lang.Object

org.orekit.propagation.analytical.gnss.FieldClockCorrectionsProvider<T>

Type Parameters:

T - type of the field elements

All Implemented Interfaces:

FieldAdditionalDataProvider<T[],T>

public class FieldClockCorrectionsProvider<T extends CalculusFieldElement<T>>
extends Object
implements FieldAdditionalDataProvider<T[],T>

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:

13.0

Constructor Detail

FieldClockCorrectionsProvider

public FieldClockCorrectionsProvider(FieldGNSSClockElements<T> gnssClk,
                                     double cycleDuration)

Simple constructor.

Parameters:

gnssClk - GNSS clock elements

cycleDuration - duration of the GNSS cycle in seconds

Method Detail

getName

public String getName()

Get the name of the additional data.

If a provider just modifies one of the basic elements (orbit, attitude or mass) without adding any new data, it should return the empty string as its name.

Specified by:

getName in interface FieldAdditionalDataProvider<T extends CalculusFieldElement<T>[],T extends CalculusFieldElement<T>>

Returns:

name of the additional data (names containing "orekit" with any case are reserved for the library internal use)

getAdditionalData

public T[] getAdditionalData(FieldSpacecraftState<T> state)

Get the additional data.

Specified by:

getAdditionalData in interface FieldAdditionalDataProvider<T extends CalculusFieldElement<T>[],T extends CalculusFieldElement<T>>

Parameters:

state - spacecraft state to which additional data should correspond

Returns:

additional data corresponding to spacecraft state
