Offshore wind turbines use fixed aerials to send operating data through a relay satellite.
The proposed satellite would move in a circular orbit in the same direction as the Earth rotates. It would take 20 hours to complete each orbit and its path would cross above latitudes north and south of the equator.
Explain two changes that should be made to the proposed orbit so that the aerials can remain directed towards the satellite.
