1.	The intentional degradation of GPS signal in specific areas is called ________(a) Selective degradation(b) Selective availability(c) Distributed GPD(d) Signal jammingThe question was posed to me at a job interview.Origin of the question is NAVSTAR GPS in chapter Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» Right answer is (b) Selective availability To elaborate: The INTENTIONAL degradation of GPS SIGNAL is meant to deny accuracy to unfriendly forces. It is known as selective availability. SA also denies accuracy to unauthorized users who are friendly, which is the ENTIRE CIVIL community.
