  • Method Details

    • computeDelays

      public double[] computeDelays(SignalReceptionCondition primaryReceptionCondition, PVCoordinatesProvider secondaryReceiver, AbsoluteDate approxSecondaryReception, PVCoordinatesProvider emitter, AbsoluteDate approxEmissionDate)
      Compute (positive) delays from emission.
      Parameters:
      primaryReceptionCondition - signal reception conditions at primary observer
      secondaryReceiver - signal secondary receiver coordinates provider
      approxSecondaryReception - guess for the secondary reception date
      emitter - signal initial emitter coordinates provider
      approxEmissionDate - guess for the emission date
      Returns:
      delays to primary and secondary respectively (s)

    • computeDelays

      public double[] computeDelays(SignalReceptionCondition primaryReceptionCondition, PVCoordinatesProvider secondaryReceiver, PVCoordinatesProvider emitter)
      Compute (positive) delays from emission without guesses.
      Parameters:
      primaryReceptionCondition - signal reception conditions at primary observer
      secondaryReceiver - signal secondary receiver coordinates provider
      emitter - signal initial emitter coordinates provider
      Returns:
      delays to primary and secondary respectively (s)
