Methods

	Name	Description
	Equals(Object)	Indicates whether another object is exactly equal to this instance. (Overrides ObjectEquals(Object).)
	Equals(PredictionSupportRecord)	Indicates whether another instance of this type is exactly equal to this instance.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table. (Overrides ObjectGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)

Remarks

The following descriptions are from the Air Force Navigation Interface Data Description (IDD):

Orbit error statistics in the PSF are in Radial - Along Track - Cross Track (RAC) coordinates relative to the satellite's orbit. Each value nominally represents the root-mean-square (RMS) of the last seven days' worth of PAF data for that variable. If there is a gap in the data that is 3 days or greater, the RMS will not include data prior to the gap. If less than one day of data is present for a satellite, then an average of all the other satellite's values for that variable is used. No data is to be included in the RMS for any time when the satellite is unhealthy.
RMS Clock is satellite clock phase error converted to meters and is also nominally computed as an RMS of the last seven days of clock phase error data PerformanceAssessmentRecord The same shortened time interval logic is used for RMS Clock as for RMS RAC errors. No data is used for any time when the satellite is unhealthy.
RMS User Range Error is a composite term of the RMS Radial, RMS Along Track, RMS Cross Track, and RMS Clock terms computed each time increment and then averaged over the appropriate time interval (nominally seven days) for a satellite.
A, B and C Radial, Along Track, Cross Track, Clock and Age Of Data terms are set to 0 in version 1 PSF files.
