Question

Dead reckoning systems must be re-initialized as errors accumulate.

(a) True

(b) False

This question was addressed to me by my college professor while I was bunking the class.

Enquiry is from Guidance and Navigation in chapter Introduction & Navigation Equations of Avionics

Answer 1

The correct answer is (a) True

Easy explanation: Dead reckoning systems use gyroscope and accelerometer whose readings suffer from drift error as time progresses. Thus it is necessary to reinitialize after a particular time interval as errors accumulate and if the electrical power is lost.
