Class 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
