The identification of the 64 satellites launched by SpaceX SSO-A mission on December 3, 2018 continues. The concensus is that the spacing between unidentified satellites is growing to a point where positive identification may now be possible. In the past, two weeks after launch has been the time when distance between cubesats increases enough to identify most individual satellites. We will see. There are no major changes to the previous AMSAT-NA TLE Distribution (Monday, December 17, 2018) for the IDENTIFIED SSO-A lau ...Continue Reading

Sorry. I left out AO-85, NO-83 and NO-84 again. I got out of my process and skip one step! Use AMSAT-NA TLE distribution orb18351.2l.amsat (sent Monday,12-17-2018)and delete the KEP email of Sunday,12-16-2018. _______________________________________________ Via the Keps mailing list courtesy of AMSAT-NA http://www.amsat.org/mailman/listinfo/keps ...Continue Reading

In case you missed Nico Janssen's,PA0DLO,comments on AMSAT-BB, here is Nico's assessment of our current situation concerning the identification of the 64 satellites launched by SpaceX SSO-A mission on December 3, 2018: "With nearly all TLE sets for the SSO-A launch published, and many separations increased to more suitable values, it is time to draw some conclusions. The following IDs are (almost) certain: Unknown sat: obj 43768, downlink 436.73018 MHz; MOVE-II: obj 43780, downlink 145.94993 MHz; SNUSat 2: o ...Continue Reading
