Remarks
Gets 'Accumulated Delta Range' state.
This indicates the state of the #getAccumulatedDeltaRangeMeters() measurement. See the table below for a detailed interpretation of each state.
<table border="1"> <thead> <tr> <th>ADR_STATE</th> <th>Time of relevance</th> <th>Interpretation</th> </tr> </thead> <tbody> <tr> <td>UNKNOWN</td> <td>ADR(t)</td> <td>No valid carrier phase information is available at time t.</td> </tr> <tr> <td>VALID</td> <td>ADR(t)</td> <td>Valid carrier phase information is available at time t. This indicates that this measurement can be used as a reference for future measurements. However, to compare it to previous measurements to compute delta range, other bits should be checked. Specifically, it can be used for delta range computation if it is valid and has no reset or cycle slip at this epoch i.e. if VALID_BIT == 1 && CYCLE_SLIP_BIT == 0 && RESET_BIT == 0.</td> </tr> <tr> <td>RESET</td> <td>ADR(t) - ADR(t-1)</td> <td>Carrier phase accumulation has been restarted between current time t and previous time t-1. This indicates that this measurement can be used as a reference for future measurements, but it should not be compared to previous measurements to compute delta range.</td> </tr> <tr> <td>CYCLE_SLIP</td> <td>ADR(t) - ADR(t-1)</td> <td>Cycle slip(s) have been detected between the current time t and previous time t-1. This indicates that this measurement can be used as a reference for future measurements. Clients can use a measurement with a cycle slip to compute delta range against previous measurements at their own risk.</td> </tr> <tr> <td>HALF_CYCLE_RESOLVED</td> <td>ADR(t)</td> <td>Half cycle ambiguity is resolved at time t.</td> </tr> <tr> <td>HALF_CYCLE_REPORTED</td> <td>ADR(t)</td> <td>Half cycle ambiguity is reported at time t.</td> </tr> </tbody> </table>
