[amsat-bb] BIRDS-1 Constellation deployed from ISS

[Nico Janssen]

All,

Note that the TLE set for object 42822 is useless in this form: the 
decay rate
and B* term have unrealistically high values. You could replace these with
values similar to the other TLE sets, but probably it is best to wait 
for a new,
realistic TLE set.

(Btw NORAD is not involved anymore in the TLE database. This is now
maintained by the 18 Space Control Squadron (18 SPCS). Up to early April
this year this unit was called Joint Space Operations Center (JSpOC).)

73,
Nico PA0DLO
