Remarks
Gets the accumulated delta range since the last channel reset, in meters.
The error estimate for this value is #getAccumulatedDeltaRangeUncertaintyMeters().
The availability of the value is represented by #getAccumulatedDeltaRangeState().
A positive value indicates that the SV is moving away from the receiver. The sign of #getAccumulatedDeltaRangeMeters() and its relation to the sign of #getCarrierPhase() is given by the equation:
accumulated delta range = -k * carrier phase (where k is a constant)
Similar to the concept of an RTCM "Phaserange", when the accumulated delta range is initially chosen, and whenever it is reset, it will retain the integer nature of the relative carrier phase offset between satellites observed by this receiver, such that the double difference of this value between receivers and satellites may be used, together with integer ambiguity resolution, to determine highly precise relative location between receivers.
The alignment of the phase measurement will not be adjusted by the receiver so the in-phase and quadrature phase components will have a quarter cycle offset as they do when transmitted from the satellites. If the measurement is from a combination of the in-phase and quadrature phase components, then the alignment of the phase measurement will be aligned to the in-phase component.
