Abstract:
1. A system for evaluating a physical location of a node in a network within an aircraft comprising: a reference node having a reference accelerometer installed in a reference orientation; a first node accelerometer coupled to a component and installed at a first location and in a first node orientation relative to the reference orientation; a memory configured to store the first node orientation and an initial acceleration vector of the first node accelerometer; and a controller configured to receive a current node acceleration vector associated with the first node accelerometer and a current reference acceleration vector associated with the reference accelerometer, determine a current node orientation by comparing the current node acceleration vector to the current reference acceleration vector, and to determine whether a current orientation of the component relative to the reference node has changed by comparing the first node orientation and the current node orientation.
