                                         Duration timeStep)

Computes Receiver Autonomous Integrity Monitoring (RAIM) outages using RTCA values.

The standard RTCA summed, squared error (ReceiverAutonomousIntegrityMonitoring.Rtca208SummedSquaredError) is used for the test statistic.

Parameters:

receiver - The receiver for which to compute RAIM.

start - The start of the interval for which to compute RAIM outages.

stop - The end of the interval for which to compute RAIM outages.

timeStep - The step at which to sample RAIM.

Returns:

The outages for each flight phase over the given analysis interval.

Throws:

ArgumentNullException - Thrown if receiver is null.

ArgumentException - Thrown if timeStep is greater than the default OutageDurationThreshold (get / set) in RaimOptions.
