Abstract

Claims (32)

1. A guidance kit for a projectile, comprising:

at least one processor in the guidance kit;

a guidance protocol operatively in communication with the guidance kit and the at least one processor and having a set of angular offset modes;

at least one gyroscope operatively connected with the at least one processor;

at least one accelerometer operatively connected with the at least one processor;

a set of first codes provided with the guidance kit; and

a first angular offset mode of the set of angular offset modes operatively in communication with the set of first codes;

wherein the guidance protocol is configured to guide the projectile to at least one location relative to a desired point-of-interest (POI) upon or in response to activation of at least one angular offset mode of the set of angular offset modes;

wherein the at least one gyroscope and the at least one accelerometer are configured to determine a down acceleration direction of the projectile at a predetermined time subsequent to launching the projectile from a launch vehicle; and

wherein the first angular offset mode is configured to activate the guidance protocol between an ON state and an OFF state.

2. The guidance kit of claim 1 , further comprising:

at least one code of the set of first codes designates the first angular offset mode to activate the guidance protocol to the ON state.

3. The guidance kit of claim 2 , further comprising:

at least another code of the set of first codes designates the first angular offset mode to deactivate the guidance protocol to the OFF state.

4. The guidance kit of claim 1 , further comprising:

a set of second codes provided with the guidance kit; and

a second angular offset mode the set of angular offset modes operatively in communication with the set of second codes;

wherein the second angular offset mode is configured to bias the projectile between a first lateral position relative to the POI and a second lateral position relative to the POI; and

wherein the first lateral position and the second lateral position are opposite to one another relative to the POI.

5. The guidance kit of claim 4 , further comprising:

at least one range of codes of the set of second codes designates the second angular offset mode to bias the projectile to the first lateral position relative to the POI.

6. The guidance kit of claim 5 , further comprising:

at least another range of codes of the set of second codes designates the second angular offset mode to bias the projectile to the second lateral position relative to the POI.

7. The guidance kit of claim 4 , further comprising:

a set of third codes provided with the guidance kit; and

a third angular offset mode the set of angular offset modes operatively in communication with the set of second codes;

wherein the third angular offset mode is configured to bias the projectile between a first longitudinal position relative to the POI and a second longitudinal position relative to the POI; and

wherein the first longitudinal position and the second longitudinal position are opposite to one another relative to the POI.

8. The guidance kit of claim 7 , further comprising:

at least one range of codes of the set of third codes designates the third angular offset mode to bias the projectile to the first longitudinal position relative to the POI.

9. The guidance kit of claim 8 , further comprising:

at least another range of codes of the set of second codes designates the third angular offset mode to bias the projectile to the second longitudinal position relative to the POI.
