Abstract:	This paper summarizes the results of developing two alternative approaches for deriving strapdown attitude and navigation algorithms as opposed to the conventional one which is used until now. A key point of both is the use of additional gyro and accelerometer output signals which are the incr~ ments of the angular rate/specific force multiple in-tegrals over the iteration interval. This results in new families of attitude and specific force transfor-mation algorithms which accurately account for the coning/sculling effects and attenuate the pseudo con-ing/ sculling errors that can arise because of the high-frequency gyro/accelerometer behaviour.
