Abstract: A projectile is arranged with antenna, where the projectile is intended for launch in a launch device with a propellant charge in a barrel, where the projectile is arranged with an antenna in the rear edge of the projectile, and where the antenna is arranged behind any of or a combination of: i. a protective cap which protects the antenna during the ejection phase in the barrel and which is removed when the projectile has left the barrel; and ii. a protection in the form of a molding compound arranged to protect the antenna.

Abstract: A method is provided for calculating the bursting point of at least one projectile fired at a target object, involving measuring the position of the projectile, estimating the position of the projectile, estimating the speed of the projectile, measuring the position of the target object, estimating the position of the target object, estimating the speed of the target object, calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object, and communicating the bursting points for the projectile to the projectile. A computer program, a computer system, and a weapons system are also provided.

Abstract: A method for simulating weapon effect against a specific target includes at least one model of a warhead where the model of the warhead is adapted so that the weapon effect of the warhead is simulated as a volume. A method for simulating weapon effect against a specific target including at least one model of a warhead and a computer program product is also provided.

Abstract: A method for simultaneous blasting of projectiles includes i.) calculating the position of the target, ii.) estimating the target's position, iii.) firing a first projectile at the target, iv.) firing a second projectile at the target, v.) braking the first projectile with a braking device arranged in the projectile, and vi.) detonating the projectiles in a coordinated fashion based on an initiation signal. A fire-control system for directing fire against a target comprising at least one sensor, in order to measure the position of the target as a function of time, and a combat system including a firing device are also provided.
