All,
Finally the separation between UKube 1 and AISSat 2 has increased to
about 60 km. And with the telemetry beacon transmitting a continuous
signal, it now became possible to identify UKube 1 using doppler
measurements. It appears that UKube 1 is object 40074, 2014-037F.
So the JSpOC's initial
All,
Doppler measurements suggest that UKube 1 is either object 40074,
2014-037F, or object 40075, 2014-037G. The separation between these
objects is now only 1 s, so no more than 7.5 km.
It is not easy to carry out meaningful doppler measurements because of
the limited transmissions from the

Using doppler measurements I find that Dauria DX 1 is object 40071,

Using detailed doppler measurements I find that DUCHIFAT is definitely
object 40021, 2014-033M.
Operators of DTUSat 2 confirm that their satellite is object 40030,

So now it is up to Planet Labs to determine which of the objects 40022

It seems that the JSpOC has changed some of their policies lately.
After the launch of multiple small satellites late last year it took
a long time to get them all identified. Apparently they don't want to
leave all the TBAs in their database for a long time, so now they use
a different
