Why we measure position using an instrument that measures acceleration? Because we don’t have a choice. In larger spaces where the vehicle travels, there are no fixed references that can be followed. And when there is a global fixed reference available, like GPS, it may not be enough to stand alone for the application. It is common to see inertial navigation systems aided by other measuring systems. Nonetheless, the fact is that current navigation systems are very reliable.
In this video we see what we expected to see from the theoretical analysis in Part 1.
