Abstract
A system for firing a projectile mounted on a carrier, the decision assistance system comprising: a first simulator for simulating a navigation system of the carrier and configured to produce a precision of a solution for navigation of the carrier; a second simulator for simulating a navigation system of the projectile and configured to be initialized with the precision of the solution for navigation of the carrier and produce a precision of a solution for navigation of the projectile; and a selector configured to select or not the projectile as projectile to be fired as a function of the precision of a solution for navigation of the projectile.
Claims14
A decision assistance system comprising:
- a first simulator for simulating a navigation system of a mobile carrier, the first simulator being configured to apply a first processing repeatedly to a first set of simulated data representative of a configuration of the mobile carrier and of a trajectory of the mobile carrier between a first instant and a second instant so as to produce prior to the second instant a precision of a solution for navigation of the mobile carrier associated with the second instant,
- a second simulator for simulating a navigation system of a projectile mounted on the mobile carrier, the second simulator being configured to:
- a) be initialized with the precision of the solution for navigation of the mobile carrier associated with the second instant, then
- b) apply a second processing repeatedly to a second set of simulated data representative of a trajectory of the projectile between the second instant and a third instant so as to produce prior to the third instant a precision of a solution for navigation of the projectile associated with the third instant,
- a selector configured to select or not the projectile as projectile to be fired at a target, as a function of the precision associated with the third instant produced in step b).
A decision assistance method comprising:
- a) applying by a first simulator a first processing repeatedly to a first set of simulated data representative of a configuration of a mobile carrier and of a trajectory of the carrier between a first instant and a second instant so as to produce prior to the second instant a precision of a solution for navigation of the mobile carrier associated with the second instant,
- b) initializing a second simulator with the precision of the solution for navigation of the carrier associated with the second instant,
- c) after initializing the second simulator, applying by the second simulator a second processing repeatedly to a second set of simulated data representative of a trajectory of a projectile mounted on the mobile carrier between the second instant and a third instant so as to produce prior to the third instant a precision of a solution for navigation of the projectile associated with the third instant,
- e) selecting or not the projectile as projectile to be fired at a target, as a function of the precision associated with the third instant produced in step c).
