Which of the following navigational systems is most stealthy?(a) Secon

1.	Which of the following navigational systems is most stealthy?(a) Secondary surveillance radar(b) VOR(c) Celestial navigation(d) SONAR
Answer» The correct choice is (c) Celestial navigation To explain: In celestial navigation, the position is computed by measuring the elevation and azimuth of celestial bodies relative to the navigational coordinate frame at precisely known times. Since it is a completely passive system, it is considered to be stealthy and is used in special purpose high altitude aircraft in conjunction with an inertial navigator.
