Claim:
1. A stabilization system for an equipment positioner with motorized axes, the positioner being oriented under the action of a command of orientation following a line of sight/pointing, said positioner being installed on a vehicle, the vehicle undergoing movements referred to as bearing movements, the positioner including angle encoders producing angle measurements (θ p , θ t ) for said axes and a set of gyrometer sensors producing measurements of equipment instantaneous rates of rotation (m y , m z ), said gyrometer sensors exhibiting biases (p y , p z ), the positioner including gyrometer sensors for at least two axes (y) (z) of the equipment reference system, the positioner including a calculation unit with intra-positioner means for servo control-correction of the instantaneous rates of rotation of the equipment using measurements and the command of orientation for stabilizing the equipment following the line of sight, the system configured to be installed in the vehicle where the vehicle includes a means for measuring the vehicle attitude, giving measurements of attitude of the vehicle, wherein the system includes: wherein the command of orientation is expressed by means of a command of instantaneous rate of rotation, and the pointing drift corrector implements a feedback and feedforward calculation structure based on the estimated equipment structure (
