A method for determining navigation parameters of a vehicle under varying center of gravity position, the method comprising, detecting a plurality of acceleration values via a plurality of accelerometers, calculating a plurality of differential values based on the acceleration values, calculating an initial inertia value of the vehicle based on the differential values, calculating an initial mass value of the vehicle based on the differential values, obtaining a plurality of disturbance parameters, calculating a refined inertia value based on the initial inertia value and a first one of the disturbance parameters, calculating a refined mass value based on the initial mass value and a second one of the disturbance parameters, and determining navigation parameters based on the refined inertia value and the refined mass value.
