5 Inertial navigation accuracy
Pages 1

The accuracy of an inertial navigation system

depends on a number of factors including: the

precision of the accelerometers and gyros; and the

accuracy of alignment with respect to true north

and local vertical. Errors in the system will build

up as a function of time; typical errors of between

one and two nautical miles per hour should be

allowed for; however, smaller errors can be

achieved.
