Mike, You are probably right. I'll also try my measurement method on those satellites. But their AFSK signals are not so suitable for this type of measurement. In this case your method works better.
If you look at the mean anomaly and argument of perigee in the group of 2-line element sets for these Cubesats, you can see that there are actually two groups: 38852 and 38856 (let's say group A) and 38853, 38854 and 38855 (group B). We know that the Cubesats were launched in two groups at different times and at different points in the orbit of the ISS. This means that WeWish and Raiko must be in group A and the other three satellites must be in group B. So if TechEdSat is 38854, WeWish is 38856 and FITSAT 1 is 38853, then we can conclude that Raiko is 38852 and F 1 is 38855. So to summarise the identifications for these Cubesats: 38852 = Raiko 38853 = FITSAT 1 38854 = TechEdSat 38855 = F 1 38856 = WeWish Obviously this is only valid if the 2-line element sets are not re-assigned again to different object numbers. This has happened in the first days after the launch from the ISS and it may happen again... 73, Nico PA0DLO On 2012-10-10 22:24, Mike Rupprecht wrote:
Hi Nico, yes - and TechEdSat is #38854 and We-Wish is #38856... 73 Mike DK3WN -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Nico Janssen Gesendet: Mittwoch, 10.
