A simple test to determine nonlinear system observability is presented here and applied to several examples. Most interesting is the bearing- only tracking example which shows the need for relative maneuvers. A mixed- coordinate system is compared favorably to the standard rectangular coordinates and the popular modified polar coordinates for accuracy with a continuous- discrete truncated second-order filter.
