1. The parking orbit of an Earth satellite has apogee and perigee altitudes of 850 km and 250 km, respectively (this orbit is sometimes referred to as an 850 km x 250 km orbit). (a) Determine the delta v required to circularize the orbit using a single-impulse burn at perigee. What is the period of the resulting circular orbit? Sketch the two orbits, indicating the point where the impulsive burn occurs. (b) Determine the delta v required to circularize the orbit using a single-impulse burn at apogee. What is the period of the resulting circular orbit? Sketch the two orbits, indicating the point where the impulsive burn occurs. (c) Compare parts (a) and (b); which is the least “expensive”. (d) Determine the delta v required to escape from the perigee of the parking orbit. (e) Determine the delta v required to escape from the apogee of the parking orbit. (f) Compare parts (c) and (d); which is the least “expensive.”
