Orbitel is memory limited for today's TLE lists and there won't be any fix... R.I.P. Dave Ransom... like Orbitel and your tool, my tool takes a list of TLEs, merges them all together and outputs the results by whatever criteria you desire based on their data... the main thing, if not allowing duplicates, is to keep and use the newest TLEs for processing... the tool also offers XRF (cross reference) like Orbitel does/did so that your output file can contain your preferred common names for the objects instead of some "cryptic" id assigned by others... in addition to XRF, it also uses Dr. Jonathan's satcat list for similar naming capability... eg: 07530 has several common names... use the one you like... OSCAR 7 (AO-7) AMSAT-OSCAR-7 AO-7 additionally, the satcat is used to identify known/unknown objects and orbiting/non-orbiting objects... objects that are "unknown" are simply not listed in the satcat file... they are marked with an '_at_' as the first character in their output common name... down objects, as indicated in the satcat file "REENTERED" or similar, are marked with an '!' as the first character in their output common name... _at_Explorer 1 <- unknown object common name !Explorer 4 <- non-orbiting object common name for fun, here's an example of one of my processing commands... satsort32 -l logs/geosync.log -o geosync.3le -i alltles.new -c -u --mmotion=0.99,1.01 --eccen=0,0.01000001 it creates an output file of objects that have a mean motion between 0.99 and 1.01 that also have an eccentricity between 0 and 0.01000001... there's also SEL files like Orbitel has/had... they restrict processing to only the objects listed in that SELection file... this allows you to slice and dice your input while restricting it to only a specific SELection of objects... eg: use the CLASSFD.SEL to limit the above geosync.3le to only those objects in the classfd list... this would be if you maintain a large central tle list (aka database)... sure, you could use classfd.tle as the input instead of alltles.new as above... this gives you another way to do the same thing ;) don't be confused by the executable's name, satsort32... 32 was initially used to differentiate from 16bit like Orbitel but the program compiles on OS/2 32bit, linux 32bit, linux 64bit and it should also compile on winwhatever 32bit and 64bit... i haven't a winwhatever box to test with any more, though... future plans call for allowing for outputting TLEs for craft that will fly over a certain longitude and latitude over a certain time frame... it isn't a GUI tool but that may change if i can ever figure out GUI programming ;) -- NOTE: No off-list assistance is given without prior approval. *Please keep mailing list traffic on the list unless* *a signed and pre-paid contract is in effect with us.* _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Mon Feb 19 2018 - 12:04:35 UTC
