      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...

Hi Nico,
yes - and TechEdSat is #38854 and We-Wish is #38856...

Hi,
Using very accurate dopplershift measurements, I found that FITSAT 1 is
object 38853, 1998-067CP.
