METHOD AND DEVICE FOR IMPROVING THE INERTIAL NAVIGATION OF A PROJECTILE |
| 摘要 |
According to the invention, before firing said projectile (M) from the carrier (L), the mean biases of the accelerometers and of the gyrometers of the inertial unit (IM) of said craft are determined using the inertial unit (IL) of said carrier (L) and, during the inertial navigation of said craft (M), the measurements of the accelerometers and of the gyrometers output by said inertial unit (IM) of said craft (M) are corrected by said mean biases determined before launching. |

1. Method for improving the inertial navigation of a projectile (M) equipped with a mediocre-quality inertial unit (IM) and fired from a carrier (L) equipped with a precision inertial unit (IL), comprising the following steps:
before the firing of said projectile (M) from the carrier (L), the mean biases of the accelerometers and of the gyrometers of the inertial unit (IM) of said projectile are determined by means of the inertial unit (IL) of said carrier (L); and during the inertial navigation of said projectile (M), the accelerometric and gyrometric measurements provided by said inertial unit (IM) of said projectile (M) are corrected by said mean biases determined before firing. |
