Orbit file

The wizard will create a multi orbit object by reading an orbit file. A multi orbit object is a time-ordered sequence of orbit state vectors obtained from the orbit file.

Several orbit formats are possible:

• XML Earth Explorer Reference Orbit Files (MPL_ORBREF_...)

  • See example here

• XML Earth Explorer Reference Orbit Scenario File (MPL_ORBSCT_...)

  • See example here

• Two Line Element historical sets, as a continuous sequence of <Line1><Line2>

  • See example here

• Orbit Messages (OEM, OMM, OPM) according to CCSDS 502.0-B-3 April 2013

  See examples here:

  • OEM (Orbit Ephemeris Message): TEXT, XML.

  • OMM (Orbit Mean-Elements message):  TEXT, XML.

  • OPM (Orbit Parameter message ):  TEXT, XML.

• Text files with one orbit state vector per row in column format.

  • See example of column based format here.

• Column format string

• Repeat cycle

• Interpolation degree
