1.Distance : r0
when The satellite started to run , the Distance between the satellite and the center of the earth
2.Speed (including size and direction): v0 and θ0when The satellite started to run , the instant speed of the satellite
the equation of a Satellite orbit is shown as below :
Other symbols : p , e , @ , are constants :
Therefore,
we can know that the orbit has already been decided at The moment of formal operation
by the equation , the orbit of a satellite will be a Conic curve ,
may be an ellipse , an hyperbola or a parabola
if e is less than 1 , the orbit is an ellipse
in this case ,
the satellite runs under the influence of the earth's gravity
its turns around the Earth at an appropriate speed
and
if e equals to 1 , the orbit will be a parabola
and be an hyperbola if e is larger than 1
in these two cases , the satellite will get away from the earth .
