Coordination of pulse repetition frequency (prf) codes in laser-guided applications

Abstract

A method includes removably coupling a projectile interface of a dongle to a dongle interface of a projectile. The method also includes loading a dongle code from the dongle onto the projectile. The dongle code identifies a pulse repetition frequency (PRF) code to be recognized by the projectile. The dongle code may be unique to an operator of the projectile. The method may further include, prior to loading the dongle code onto the projectile, loading an operator code onto the projectile, where the dongle code is loaded onto the projectile in response to the projectile authorizing the operator code. There may be a limited number of uses of the dongle code with different projectiles, and/or there may be a limited amount of time for using the dongle code. A companion electronic device may be used to authenticate the dongle.
