Inertial navigation is an “initial value” process in which a vehicle’s location is deduced by adding distances moved in known directions to the known position of the starting point. Errors in the deduced location come from imperfect knowledge of the starting conditions, from errors in the strapdown computation, and from errors in the gyros and accelerometers (referred to as sensors). In Chapter 1 we alluded to gyro bias when describing gyrocompassing, without defining it; here we will consider sensor performance more rigorously. For the most part we will follow the terminology used in IEEE Standard 528 [1].
