Abstract
A system for estimating mass of a ULD while on-board a vessel includes a system controller energizing one or more PDUs in communication with a conveyance surface of the vessel, the PDUs applying first and second forces to the ULD and transmitting first and second force parameters to a system integrator, one or more sensors measuring first and second accelerations of the ULD when the ULD moves into one or more sensing zones as a result of the forces and transmits first and second acceleration parameters to the system integrator, and the system integrator, which receives the first and second force parameters, and the first and second acceleration parameters, and calculates the mass of the ULD while the ULD is on-board the vessel by performing regression analysis on ordered pairs including the first force parameter and the first acceleration parameter, and the second force parameter and the second acceleration parameter.
