RinexNavigationRecordGetDataFromMostRecentEphemeris Method

Retrieves the RinexNavigationEphemeris defining all characteristics of this satellite which represent the most recent ephemeris prior to date, compared to TransmissionTime.

Namespace:  AGI.Foundation.Navigation.DataReaders
Assembly:  AGI.Foundation.Navigation (in AGI.Foundation.Navigation.dll) Version: 21.2.409.0 (21.2.409.0)
Syntax
public RinexNavigationEphemeris GetDataFromMostRecentEphemeris(
	GlobalPositioningSystemDate date
)

Parameters

date
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.
Remarks
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.
