TLE module

TLE.loadTLE

*Load a TLE and returns array objects for a specific satellite :

TLE.loadTLE(path)

{
'name': string, Name,
'norad_number' :  Norad ID,
'L1': string, TLE line 1,
'L2': string, TLE line 2,
'epoch': date
 }

Path can be a URL. Adding http or https will request the SDRVM to download the file from a remote host before processing it.

Loading from Internet:

      var satlist =TLE.loadTLE('https://www.celestrak.com/NORAD/elements/amateur.txt' ) ;
      print('We have loaded ' + satlist.length + ' sat definitions.');

Loading from local storage:

      var satlist = TLE.loadTLE('/tmp/amateur.txt') ;`
      print('We have loaded ' + satlist.length + ' sat definitions.');

Define TLE manually in the code:

var TLE = new Satellite('ISS');
var loaded = TLE.setTLE(
            '1 25544U 98067A   20262.17917074  .00000067  00000-0  93590-5 0  9992',
            '2 25544  51.6432 248.2943 0000854 102.9022 344.0032 15.48951196246432'
            );
if( !loaded ) {
    print('error loading TLE for ISS ?');
    exit();
}
