Simulated training weapons can be replicas of real weapons or modified real weapons. Replica weapons are high fidelity copies utilizing some parts from the original weapons, such as trigger mechanism, sights, housing or stock. Replica weapons are suitable for those types of weapons where originals are not available or are very expensive. Modified original weapons re-uses major weapon parts such as bolt receiver, trigger block or parts of the barrel. Both replica and modified weapons are completelysafe and cannot be used for firing live or training ammunition. The simulated weapons can be completely tether-less using data radio communication and compressed gas recoil system. Simulated weapons can be equipped with a unique double stage recoil system, to ensure realistic shooting effects.

SAVIT simulates the high-precision ballistic trajectory of a projectile including the effects of wind speed and direction, air pressure,temperature, Coriolis force, bullet drift and dispersion. The ballistic simulation compensates for aimpoint detection errors such as parallax error, distance estimation error and elevation angle error, caused by the trainees distance to the screen. Target damage effects are evaluated based on the target geometric vulnerability model, type of ammunition, ammunition impact speed and ammunition impact angle.

Ballistics of ammunitions like shot-gun, grenades or mines is simulated for each sub-projectile. High accuracy of aimpoint position detection and aiming trajectory recording is one of the most important parameters of a shooting simulator, influencing the training value of the entire system. The SAVIT aimpoint detection system consists of a weapon laser transmitter with an accurate laser beam profile and a Projection Screen Sensing Camera with a resolution of 2048 x 1088 pixels and a frame rate of 300 fps. The high resolution of SAVIT cameras enables the outstanding accuracy of 0.05 mrad of aimpoint position detection. The high frame rate of SAVIT camera ensures non-jamming aiming point assignment to the individual weapons, even if laser beams from 12 weapons converge at the same point on the projection screen.

Saab's SAVIT can be provided with an Electronic Scope with an integrated video chip. The Electronic Scope provides a high resolution image of the target and high accuracy aimpoint detection. The visual system provides special effects such as air mirage that causes an optical shift of the target position at longer distances.

Conversion kits allow quick and easy integration of real weapons into training without any modification or degradation of the real weapon. Conversion kits provide the same simulated functions as replica weapons and comprise a recoil simulation module, a sensor module and a weapon interface module. The recoil simulation module for the pistol replaces the barrel and the magazine. The recoil simulation module for the rifles and machine guns is attached to the silencer mount. The contact-less sensor module is inserted into the trigger mechanism and provides complete weapon status. The weapon interface module is attached to the trainee's belt and provides weapon control and wireless communication with the system. The weapon interface module is also connected to a source of compressed gas. Compressed gas could be supplied from paint-ball CO2 bottle, also attached to the trainee belt. Such configuration allows the trainee the freedom of movement.
