How do SDP4's "Deep space" corrections to SGP4 account for the Sun's and Moon's gravity?
The Simplified Perturbations model SGP4 is used to calculate Earth satellite state vectors (position and velocity) using standard ephemeris data encoded as TLEs (Two Line Elements). According to ...

It's been over two weeks now, will the real Humanity Star please stand up?
edit: This must be some kind of record! (cf. ISRO's PSLV-C37 with 104 satellites - after 56 hours only six TLEs, which factor is greatest challenge? This time its only six total!)
At the end of ...
