Homework Statement
A satellite is in a circular polar orbit 240 km altitude. When the satellite is over the South Pole the engine is fired to achieve a polar orbit that has apogee directly over the North Pole. After the impulsive burn an observer on the North Pole observes the satellite has a velocity of 9.183 km/s. As the satellite comes over the horizon at the North Pole it is determined to have an altitude of 3670.9 km. How long with the observer be able to communicate with the satellite assuming only line of sight communications with the satellite?
Homework Equations
If Hohmann transfer, those equations.
deltav1=v2-v1
deltav2=v4-v3
The Attempt at a Solution
rp=240km+6378km
ra=3670.9km+6378km
If it is necessary to find e, I can with rp and ra. e=.206
v3=9.183km/s
Possible use of swath angle with Hohmann transfer information?
