Question

Geocentric spherical coordinates are used for short range dead reckoning navigation.

(a) True

(b) False

I have been asked this question during an interview for a job.

Question is taken from Navigation Equations in section Introduction & Navigation Equations of Avionics

Answer 1

Right option is (a) True

The best I can explain: Geocentric coordinates are sometimes mechanized in short range dead reckoning systems using spherical earth approximation. These are the spherical coordinates of the radius vector R.
