To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a:

State vector.

Explanation:

To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a state vector.

This ultimately implies that, state vectors gives a detailed description of the position and velocity of a satellite at a specific period of time. Also, the more accurate your input state vector, the more accurate would be the position, velocity and time for a satellite when trying to determine its location. Therefore, the time tag of a state vector shouldn't be too far from the present time of the day.

i had this question and the answer was 3.15 miles.
