Type: AGI.Foundation.TimeGlobalPositioningSystemDate
The date to consider.

Return Value

Type: RinexNavigationEphemeris
The most recent GPS data. Returns the first entry if the date is prior to all existing data.
The ephemeris blocks are ordered according to the TransmissionTime within the current GPS week. The GpsWeek parameter is not used in the comparison because that week is referenced to the TimeOfEphemeris and not the TransmissionTime. While there is a GPS week parameter downlinked by GPS in Subframe 1 (word 3), it is not included in the RINEX format.
