Question

Which of the following are false with respect to stellar navigation?

(a) Can be used in daylight and at night

(b) Position and altitude can be measured

(c) Non-radiating

(d) Cannot be jammed

This question was posed to me in a job interview.

I would like to ask this question from Stellar Inertial Navigation Theory topic in division Celestial Navigation, Doppler and Altimeter Radars of Avionics

Answer 1

The correct choice is (b) Position and altitude can be measured

For explanation: High precision stellar inertial navigation systems have been developed with automatic daylight and night star tracking system. These are highly useful for military aircraft in that they provide accurate position and attitude information, are autonomous, non radiation and are invulnerable to jamming.
