Satellite Orbital Mechanics Quiz Q.1)  Orbit has eccentricity of 0.15 and semi major axis of 9000 km. Determine Periodic time and Apogee height. Q.2)  For a satellite perigee & apogee height is 300 km and 42000 km respectively. Find velocities at apogee & perigee by assuming earth radius 6378 km. Q.3)  Sum & difference of apogee and perigee distances are 50000 km & 30000 km for a certain elliptical satellite orbit. Determine eccentricity. Q.4)  If apogee height and perigee height is of 39342 km & 613 km. Determine semi major axis & eccentricity.                                                                                                        ...
