Class TwoLeggedSignalTimer

java.lang.Object
org.orekit.signal.TwoLeggedSignalTimer
public class TwoLeggedSignalTimer extends Object
Class for two-way signal travel time. A signal is emitted, received a first time (relay/reflection) and received again a final time. There is no further assumption.

  • Method Details

    • computeDelays

      public double[] computeDelays(SignalReceptionCondition endReceptionCondition, PVCoordinatesProvider relay, AbsoluteDate approxRelayDate, PVCoordinatesProvider emitter, AbsoluteDate approxEmissionDate)
      Compute first and second leg delays.
      Parameters:
      endReceptionCondition - end signal reception condition
      relay - signal relay (initial reception) coordinates provider
      approxRelayDate - guess for the relay date
      emitter - signal initial emitter coordinates provider
      approxEmissionDate - guess for the emission date
      Returns:
      delays on both legs in chronological order (s)

    • computeDelays

      public double[] computeDelays(SignalReceptionCondition endReceptionCondition, PVCoordinatesProvider relay, PVCoordinatesProvider emitter)
      Compute first and second leg delays without guess.
      Parameters:
      endReceptionCondition - end signal reception condition
      relay - signal relay (initial reception) coordinates provider
      emitter - signal initial emitter coordinates provider
      Returns:
      delays on both legs in chronological order (s)
