Examples of non-inertial references

There are a number of examples that are non-inertial in nature due to the fact that they experience acceleration or deceleration and a point of reference at the same time. A good example in our daily lives is the force we experience whenever there is a sudden deceleration or acceleration of a vehicle when we are inside. The reason why we feel the force away or towards our seats depending on the motion of the vehicle is simply because of the unwillingness of our bodies to abrupt alteration in motion. This, therefore, means that there is no actual force applied on our bodies but only the vehicle’s change in velocity.

The other example of non-inertial reference which is actually its application is the non-inertial GPS multisensory system of navigation. This GPS sensor uses the provisions of the non-inertial reference to mitigating the effects of Doppler errors on the movement of bodies and hence improving navigation performance. Doppler system equipment is usually used to provide accurate positions during a GPS outage.
