The PMAL will be a compact multi-function laser device, integrated optionally at the external side of an astronaut’s suit.

It will be used as a Laser Doppler device – pointer – distance meter – emergency position indicator – morse signal beacon.

The laser beam will be selected in the visual wavelength and in safe margins of output power. Special attention must be given during the design of the PMAL, on product safety (e.g. short-circuit fire) and the possible effects on other equipment onboard the suit, the targets etc. (e.g HIRF) in the working environment of space.

The readings of the PMAL could be shown on the helmet mounted displays of the astronauts and could also be used as verification inputs for other devices (e.g. space walk personal thrusters).
