I see satcat numbers and object names for 105 total objects;
41948 2017-008A through
42052 2017-008DJ. It looks like only six deployed satellites have TLEs so far
DJ appearing to be the fourth stage of the PSLV rocket still in orbit.
24 hours 56 hours is longer than I expected for first TLEs to be released.
I'm pretty sure this is quite a challenge, and I can think up a number of them here:
- n > 100
- low radar cross-secction
- low optical cross-section
- no telemetry or on-board GPS fixes reported from satellite owners
Do any of these (or other) factors stand out as a primary reason why this would be so challenging? Are any of them not really a reason?
Videos below: P- and P+ views appear to be nadir and zenith cameras.
These are pretty darn cool videos - but check that your volume is not at maximum before playing. Vids similar but not the same, waiting for a single definitive video to post instead.
