OSE provides with multi-scale imagery solutions thanks to its advanced optical payloads for small satellites and UAV systems.OSE proposes a new way to design space instrumentation for Earth observation, especially through additive manufacturing optimization.The specific payloads we are developing are based on advanced design, calculation and structure optimization of opto-mechanical and optical systems. It enables to enhance imaging quality, propose differentiating uses, bring new product functions while improving orbiting cost by lightweighting and miniaturizing structures.OSE's development are focused on a systematic and rigorous scheme with a complete value chain management. We customise and adapt quickly any payload to specific mission criteria while keeping high performances and affordable solutions. This organization enables to fully break standard space development and aims to reduce data acquisition costs as well as time to deployment of complete earth observation solutions.OSE's multi-scale solutions makes new missions possible, thus procuring a new valuable data-set.
