The Chinese cubesats LONGJIANG 1 (ID 43471) and LONGJIANG 2 (ID 43472) have now reached lunar orbit. Therefore, the SpaceTrack TLEs and the normal tracking programs are no longer up to the task. See the postings of Nico Janssen, PA0DLO, on AMSAT-BB for a solution to tracking these lunar orbiters. The following cubesat TLEs have been removed from this week's AMSAT-NA TLE distribution: LONGJIANG 1 - NORAD CAT ID 43471 LONGJIANG 2 - NORAD CAT ID 43472 Ray Hoad WA5QGD AMSAT-NA Orbital Elements Manager _________________ ...Continue Reading

The NORAD CAT IDs for UBAKUSAT and 1KUNS-PF have been swapped. Nico, PA0DLO reports that detailed Doppler measurements indicate that the NORAD CAT IDs are as follows: 1KUNS-PF is NORAD CAT ID 43466 UBAKUSAT is NORAD CAT ID 43467 Please make the appropriate changes to your tracking program. Also per Nico Janssen, PA0DLO, two Chinese microsats (LONGJIANG 1 and 2 ) have been launched towards the moon from Xichang on 05-20-2018 around 21:00 UTC. The following cubesat TLEs have been added to this week's AMSAT-NA TLE dist ...Continue Reading
