DIGI_NED.TLE

The Satellite Database File "digi_ned.tle". This database is stored in a flat ASCII file and can be edited with any text editor. But there is no real need for that. DIGI_NED uses this file for it's output when the 'utle' command is executed.

  • For each satellite entry there are 3 lines of information in the database.
  • The first line contains some general information of the satellite like its name, its 4 letter Amsat designator, uplink and downlink frequencies and the mode.
  • The next two lines contain the NASA Two Line Element information for that satellite.

You can delete a satellite by simply deleting the three lines corresponding to that satellite. A satellite can be added by simply editing the database file and inserting the three lines of information of that satellite.

Make sure that the first line is formatted correctly. Just look at the line format for the other satellites to see how the first line needs to be formatted.

  • The maximum number of satellites that can be specified in the database is 24.

Usually this file resides in the same directory as the DIGI_NED executable. See the Configuration section for more information about the location of the database.
