Abstract
A method includes determining a rotational position of a rotating projectile as a function of an orientation of a sensor on the rotating projectile. The method also includes actuating a steering mechanism on the rotating projectile at the determined rotational position. The method also includes altering the trajectory of the rotating projectile.
Claims19
A method comprising:
- firing a projectile from a firing mechanism;
- sending, from a transmitter operatively connected to the firing mechanism, a first signal to the projectile, wherein the first signal includes instructions to actuate a steering mechanism of the projectile at a rotational given position of the projectile;
- determining, with a processor on the projectile, that the projectile is at the given rotational position as a function of an orientation of a sensor on the rotating projectile;
- actuating a steering mechanism on the rotating projectile at the given rotational position;
- and
- generating a second signal as a function of the orientation of the sensor, wherein the sensor generates the second signal and wherein the orientation of the sensor correlates to the rotation of the projectile;
- converting the second signal to a third signal, wherein an operational amplifier on the projectile converts the second signal to the third signal and wherein the third signal is standardized to a semiconductor;
- and
- determining the rotational position of the projectile as a function of the third signal, wherein a processor of the projectile determines the rotational position.
