Due to similar measuring technology, using an accelerometer as an inclinometer is prevalent. In this study, embedded accelerometers of an inertial navigation system will be used to measure inclination in two different approaches, while they also measure acceleration simultaneously. Since inclination measurement is required during leveling in alignment period, using embedded accelerometers of inertial navigation system instead of additional inclinometers, reduces cost, weight and size of final product. Testing tactical grade accelerometers and comparison to accurate inclinometers confirmed that the suggested methods are practical for accurate accelerometers, and attained accuracy is equivalent to high end inclinometers
