Small Arms Transmitter (SAT)

The Laser Projector (also known as transmitter or small arms transmitter) is clamped to the barrel of the player’s weapon (such as an infantry weapon, sniper rifle, machine gun, light support weapon, etc.), and emits a coded infrared laser beam when the player fires the weapon (using a blank round or pressing the optional dry-fire switch).

The projector detects the firing pin striking the cartridge and the internal microphone detects the acoustic and pressure wave generated from the blank fire explosion. The projector can be set to fire in the following modes: Blank, Dry, and Auto. The projector operates off a rechargeable AA sized cell.

If aimed accurately at an opponent, it activates detectors on the opponent’s manwear harness, which will record a ‘hit’ (which can be a ‘kill’, ‘injury’, or ‘near miss’ depending on how the laser beam emitted by the projector is aimed). The laser code fired contains shooter’s ID, type of weapon, and type of ammunition.

Projector and Harness in a typical exercise

In response to the same firing event, communication occurs (through the IR link) between the weapon projector and the harness of the player holding the weapon to ensure that the action of shooting is valid, i.e., the player is ‘alive’.

If the shooter is ‘killed’ then the projector will not fire. However, the projector of a ‘dead’ player can be picked up by an ‘alive’ player; projector then forms a new association and will fire again with the ‘alive’ player’s ID.

Projectors and harnesses are “associated” (ownership established) with one another, i.e., the ID and state of shooter is passed from the harness to the projector via the IR link. As shot activity occurs the number of shots fired by the associated projector is stored in the harness.

Through the projector comms port optical link (opto-port) the Umpire Control Gun (UCG) is used to program the projector to the various weapon types, laser codes and firing modes as needed. Over the IR link, shots data is passed onto and stored in the harness worn by the shooter and is downloaded by the UCG and transferred to the Combat Analysis System (CAS) software on a PC/laptop for printing reports for after action review.

The projector laser tube is rapidly aligned to the weapon sights using the Mini Automatic Transmitter Alignment System (MATAS), or the projector can be manually aligned in the field using a harness or laser locator.

The laser projector fires Class 1 eye safe for normal usage pulsed infrared laser beams to simulate bullets.

Machine Gun Laser Transmitter (MGLT)

The MGLT is a common transmitter configured with its particular weapon type and ammunition to replicate the weapon's performance. The MGLT differs from the other small arms transmitters in the clamp. Two types of clamp are available; the first enables the transmitter to be attached directly to the barrel, while the second is offset to enable barrel change without removal of the transmitter.

Transmitter Clamps

The SAT or Projector is mounted using a bracket or clamp on the barrel. The placement of the transmitter does not affect, in any way, the operation or use of the weapon including the weapon sights (both iron sight and/or scope). There is NO modification required to the weapon to accommodate the transmitter. The transmitter configured is also common to a range of weapons (e.g., sniper rifles, infantry weapons, machine guns, etc.) and is simply programmed with its particular weapon type and ammunition to replicate the weapon's performance.

Clamping methods designed for each weapon type ensure reliable fixing of the transmitter to the weapon. Clamps are designed specific to a weapon and many kinds of clamps are available as shown in these pictures.
