<ul><li>Using the formula v² = μ/r, the altitude of a satellite can be estimated based on its speed and standard gravitational parameter.</li><li>The apparent angular velocity of a satellite in an orbit can be calculated using the formula v/r = √(μ/r³), where v is the velocity and r is the orbit radius.</li><li>By subtracting the earth's angular velocity from the satellite's angular velocity, the apparent angular velocity from the perspective of an observer on the surface of the earth can be obtained.</li><li>To estimate the altitude of a satellite, its apparent angular velocity can be compared to the angular size of the moon or a region of space.</li></ul>
