Hello,

 

This question is driving me mad and I cant figure it how to solve this.

 

Given: inclination angle 98 deg height of pergiee 700 km for 14 rev/day

w = 7.29211x10 -5 rad/sec

R= 6378.1363 km

mu=U= 398600.4415

 

I know that period is P = 2*pi* sqrt(a^3/U)

 

and by manipulating the period equation I can get the value of semi major axis but if you put the value in equation of e = 1 - rp/a this turn to negative which is not possible

This is going to be used in Flower Constellation.

 

Thanks in advance for any help.
