1.	The clocks are important in satellite navigation as they are potential sources of error.(a) True(b) FalseThis question was posed to me in a job interview.The question is from Orbital Mechanics and Clock Characteristics topic in division Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» Correct option is (a) True To ELABORATE: The navigational MESSAGES from a satellite INCLUDE parameters describing the satellite’s clock offset and drift, which are PREDICTED by the control segment. Any instability in the satellite’s clock CAUSES this prediction to be in error, thus resulting in range and range rate errors in the user’s navigation solution.
