Final answer:
True. The tracker node requires two tracking points.
Step-by-step explanation:
The statement is True.
In Kepler's laws of planetary motion, the first law states that the planet-satellite system must be isolated from other massive objects in order to follow the law. This is because the gravitational force between the planet and other objects can affect the motion of the satellite, leading to deviations from Kepler's laws.
For example, if there are other massive objects nearby, their gravitational pull could cause the satellite to deviate from its elliptical orbit around the planet, resulting in a violation of Kepler's laws.
