Interactive training harness

Our Personnel Detection Device allows training units to interact with and support individual soldiers during exercises.

The latest generation Personnel Detection Device (PDD) is suitable for educating and training both military personnel and police, and is now more comfortable to use. Trainers can use the operator-worn harness to follow, monitor and analyse how individuals move and operate both indoors and outdoors, and to provide simultaneous feedback. The PDD is currently in use in Sweden, Austria and Finland.



1. Laser fire detectors. A prism-based version is used during ballistic simulation with the BT 46 laser unit

2. Receptor for wireless communication between the helmet’s band and the PDD. 

3. Built-in radio antenna.

4. GPS for positioning.

5. Verification and target evaluation unit with speakers and adjustment buttons.

Speakers are used to communicate messages to users and provide sound effects in different situations. For example, the speakers might broadcast the message ‘injured, left arm’ or play the sound of an explosion followed by ‘artillery 250 metres south-west’.

Function for recording the user’s position indoors, such as during combat in buildings. Simulated ‘treatment’ can be received in the event of ‘injury’ and is transferred via infrared.

Short-range interface for communication with surrounding equipment.

6. Detectors on the front and rear of the PDD for incoming laser fire. Each detector covers 180 degrees, creating vulnerability from all angles.

7. Pocket for soldier’s identification mark and barcode for logistics management. The PDD is designed to house the required electronics and to be easy to attach to the user’s equipment.

8. Module for communication with the exercise command-and-control centre. This allows the exercise command unit to carry out real-time monitoring of the user’s position and status and to influence scenarios.

9. Battery.
