1.	Which type of navigation measure the state vector without regard to the path travelled by the vehicle in the past?(a) Dead reckoning(b) Positioning(c) Direct reckoning(d) AHRSI have been asked this question in an interview for job.My doubt is from Guidance and Navigation in chapter Introduction & Navigation Equations of Avionics
Answer» The correct answer is (B) Positioning Easiest explanation: Navigation systems can be categorized as positioning or DEAD reckoning. Positioning systems measure the state VECTOR WITHOUT regard to the path travelled by the vehicle in the PAST.
