Question

A spacecraft is in a circular orbit of 180 km altitude and inclination 30 deg. What is the spacing in kilometers, between successive ground tracks at the equator, including the effect of Earth's oblateness (that is, including the J2 effect)

Answer 1

By using Arc Length Formula, The spacing in kilometers, between successive ground tracks at the equator, including the effect of Earth's oblateness, is 30 km.

Given parameters,

θ = 30° = 30/180 radian

r = 180 km

Length of an Arc =?

The formula for arc length is given by :

Length of an Arc = θ × r,

The length of an Arc is,

$L = \frac{30}{180} * 180 = 30 km$

Thus, the spacing in kilometers, between successive ground tracks at the equator, including the effect of Earth's oblateness is 30 km.
