MATHEMATICA IMPORT/EXPORT FORMAT

TLE (.tle, .tce)

TLE geospatial file format.
Satellite data format.
Stores Keplerian parameters of satellite orbits.
TLE is an acronym for Two Line Element.
ASCII format.
Developed by the North American Aerospace Defense Command (NORAD).

Import fully supports the TLE format.

IMPORT

Import imports a TLE file, returning all position data as an array.

Import returns a three-dimensional array that represents the positions of several satellites at different times.

Import imports the specified element from a TLE file.

Import imports multiple elements.

The import format can be specified with Import or Import.

See the reference pages for full general information on Import.

ImportString supports the TLE format.

ELEMENTS

General Import elements:

	"Elements"	list of elements and options available in this file
	"Rules"	full list of rules for each element and option
	"Options"	list of rules for options, properties, and settings

Data representation elements:

	"Data"	all data elements given as an array
	"LabeledData"	data columns given as a list of rules
	"Labels"	column headers as a list of strings

Import uses the element by default.

Import gives all available data for the satellite with the specified identification string as a list of rules.

Import gives all available data for TLE record n as a list of rules.

Detailed data representation elements:

	"ArgumentPeriapsis"	angle of point of closest approach to Earth
	"AscendingNodeRightAscension"	right ascension of the ascending node
	"BStar"	atmospheric drag parameter
	"Classification"	classification identifier
	"Eccentricity"	orbit eccentricity
	"ElementNumber"	revision number of orbital element set
	"EphemerisType"	model used to generate orbital parameters
	"EpochDate"	time reference point
	"Inclination"	orbital angle of inclination
	"InternationalDesignator"	international designator (COSPAR or NSSDC name)
	"LaunchYear"	year of launch
	"MeanAnomaly"	mean anomaly parameter
	"MeanMotion"	revolutions per day
	"MeanMotionChangeRate"	first derivative of mean motion (ndot2 parameter)
	"Name"	full satellite name
	"RevolutionNumber"	number of revolutions completed by the epoch date
	"SatelliteID"	NORAD satellite number
