Hi! I have next question: we can obtain astromectric information of satellite at its few flies during one night. What software can be used for orbit improvement in this case? On http://www.coastalbend.edu/acdem/math/sats/ there is ELCORD.14 soft. Do I use it for obtain improved TLE if I obtain 2-3 TLE for some satellite for one night? Does it takes into account changing orbit under influence of precession etc.? How I can improve TLE, that obtained in different time? And another question: we have astrometry data for Lacrosse 3 (25017 NORAD), which obtained in 21-22 May 2010. Does this data intersting for somebody at present time? Orbites are change in time... -- Best regards, Vitaly (Minsk, Belarus). _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
