1. 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).
