Skills at the service of safety

PHOTOSPACE has upgraded the entire French Navy fleet of SNA Rubis type submarines from optical periscopes to all-optronic systems.

The integration of low-light PHOTOSPACE sensors, 4K Day camera and thermal camera has significantly improved the periscopes detection capabilities. Innovative software solutions adapted to the processing of images, and interconnected to the combat system have revolutionized periscopes

Strength by this experience, PHOTOSPACE designs and produces a new generation optronic mast with instantaneous 360 field of view associated with artificial intelligence for target detection: MTT1.

French Label

In 2020, the French Ministry of the Armed Forces issued to PHOTOSPACE the label « As used by French Armed Forces » for one of its periscopic mast product.
