Q.  Which of the following is the most fundamental for satellite navigation?

a. Power source in satellite
b. Position and acceleration of satellite
c. Distance from the Earth
d. Total number of satellites in the sky


ANSWER: See Answer
 
All of the satellite navigation equations have either satellite position or velocity as a variable. The linear independence of the equations, which dictate the observability of the navigation solution, is a function of the relative position of the satellites in orbit. Thus the position and the velocity of satellites is of primary importance.
