The SMS consists of a pair of stereo cameras that track a target on the head of a demining sensor, which records the position of the target thirty times per second and measures a trainee’s performance in areas critical to successful mine detection: sensor head traverse speed, sensor height above ground, coverage area, and gaps in the swept area. This information is shown on a computer display that is monitored by the training supervisor, giving immediate feedback through color, coverage, and speed vs. height plots.

The SMS also gives real time audio feedback to the trainee, beeping when mines are detected and giving verbal messages (such as “too fast” or “too slow”) about overall performance. Data recorded during training sessions can be saved and reviewed later.
