SP3dHeaderRecord Properties |
The SP3dHeaderRecord type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Accuracies |
Gets the orbital accuracy exponent as listed in the header.
The accuracy is interpreted as 2**exponent meters. An
exponent value of 0 indicates the accuracy is unknown.
The accuracies are ordered identically to the satellite identifier ordering in SatelliteIdentifiers.
|
| Agency |
Gets the generating agency.
|
| ClockStandardDeviationBase |
Gets the base number used in the calculation of the clock correction and clock correction rate standard deviations.
The standard deviation calculations are defined in the SP3d definition.
|
| Comment |
Gets the comment lines as a single String.
|
| CoordinateSystem |
Gets the coordinate system.
|
| DataUsedDescriptor |
Gets the data used descriptor.
|
| EpochInterval |
Gets the epoch interval.
|
| FileTypeDescriptor |
Gets the file type descriptor denotes the type of data included in this SP3d file. The SP3d definition
defines the types allowed:
'G' denotes data from the GPS constellation
'M' denotes data from mixed constellations/satellites
'R' denotes data from the GLONASS constellation
'L' denotes data from LEO satellites
'E' denotes data from the Galileo constellation
|
| NumberOfEpochs |
Gets the number of epochs listed in this file.
|
| NumberOfSats |
Gets the number of satellites contained in this file.
|
| OrbitType |
Gets the orbit type.
|
| PositionVelocityFlag |
Gets the Position/Velocity Flag.
|
| PVStandardDeviationBase |
Gets the base number used in the calculation of the Position and Velocity standard deviations.
The standard deviation calculations are defined in the SP3d definition.
|
| SatelliteIdentifiers |
Gets the satellite identifiers as listed in the header of the SP3d file.
For GPS satellites, these are the Pseudo Random Noise numbers and GPS constellation identifiers.
|
| StartEpoch |
Gets the start epoch, made from the epoch year, month, day, hour, minute and second.
|
| StartEpochGps |
Gets the start epoch in GPS time format, derived from the GPS week and time of week.
|
| StartFractionalDay |
Gets the start epoch fractional day.
|
| StartModifiedJulianDate |
Gets the start epoch modified Julian date.
|
| TimeReference |
Gets the time standard all data in the SP3d file is referenced to. The SP3d definition defines the types allowed:
"GPS" denotes GPS time
"GLO" denotes GLONASS UTC time
"GAL" denotes Galileo system time
"TAI" denotes international atomic time
"UTC" denotes Universal time.
|
| TimeStandard |
Gets the Time Standard used in this SP3d Ephemeris file.
|
| Version |
Gets the version of this file.
