La plate-forme inertielle de l'IU [Instrument Unit, cœur du lanceur de fusée] fournit une référence fixe qui permet au lanceur de s'orienter dans l'espace. En clair, une plate-forme inertielle, c'est un appareil qui reste toujours orienté de la même façon quoiqu'on fasse, un peu comme l'eau dans un verre. L'environnement qui entoure la plate-forme se déplace, mais cette dernière reste toujours dans la même position. Ceci permet de mesurer l'accélération et l'orientation du lanceur. 4, record 1, French, - plate%2Dforme%20inertielle

Système de navigation à inertie [...] Le système se compose d'une plate-forme inertielle, d'accéléromètres intérieurs et d'un ordinateur. La plate-forme, qui capte le déplacement de l'aéronef au-dessus du sol, comporte deux gyroscopes. Ceux-ci maintiennent leur orientation dans l'espace pendant que les accéléromètres captent toutes les variations de cap et de vitesse de déplacement. L'information provenant des accéléromètres et des gyroscopes est transmise à l'ordinateur, qui corrige la trajectoire afin de tenir compte des facteurs comme la rotation de la terre, la dérive de l'aéronef, la vitesse et la vitesse angulaire de virage. Les instruments d'attitude de l'aéronef peuvent également être reliés à la plate-forme inertielle. 5, record 1, French, - plate%2Dforme%20inertielle
