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

1.	Dead reckoning systems must be re-initialized as errors accumulate.(a) True(b) FalseThis 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» 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.
