[amsat-bb] NAYIF1 TLE'S

[Wouter Weggelaar]

Hi All,

The Joint Space Operations Center (JSpOC) will be adding lots of
objects to the database in the coming days.
Off course there is a challenge to add 104 spacecraft to the database
in one go, and the whole swarm is still quite close together.
We expect that Nayif-1 will be one of the last ones identified, as it
is "only" a one Unit cubesat, and therefore has the lowest radar cross
sectional area. So unless it separates from the rest quickly, it will
be the smallest object of the lot.

The main payload and the two secondary indian satellites have large
radar cross sections, so have been identified already
I would expect the Planet satellites to appear first, as they can do
ranging to aid the orbit determination.

So please keep using the pre-launch keps for now. We will update the
BB when we believe that we have been detected.
Off course, observations are most welcome. Precise TCA reports for
instance will help in the determination of the timing of the orbit.

Remember: there is no TLE lottery until all tickets are in the bowl ;)

Thanks for all your participation so far, the Nayif-1 team appreciates
it and is very impressed with our community!
