Double Integration

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 […]

In this video, I present some dynamical considerations about accelerometers and the double integration to obtain position. Before even considering the stochastic properties, position measurement using accelerometers has its own challenges because of the intrinsic dynamics of  integrators. I used a simple example to illustrate the problem. This simplicity allowed me to do the comprehensive […]
