HELIOS II operates in the visible and infrared spectra, providing French Defence with images both day and night. France can exchange part of this optical observation capacity with radar observation capacity being developed by its German and Italian partners. Observations are thus possible in all weather.
Amongst the improvements in the HELOS II system: a significant gain in resolution and better photography capacities, together with faster access to images. HELIOS II also allows targeting, guidance, mission preparation and combat damage verification.
