Founded in 2016, 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.

OSE additive manufacturing process




OSE offers a complete product line with high performance payloads to match each mission objective.

We design custom-made optical substrates and complete optomechanical structures using our experience, engineering simulation tools and new ways of production with additive manufacturing. We offer 3D printed products in metals & ceramics. We are able to deliver payloads for your constellation in less than 6 months.

We adapt any of our products to your needs/missions thanks to mature TRL and qualified manufacturing process.

Our objective is to deliver smarter designs than any product on the market with breakthrough technology thanks to better functionnality, reduced weight, less assembly, etc…



We can also manage your own projects from design to manufacturing stages.

Having already pre-qualified our engineering and addtive manufacturing process thanks to specific technological functions (please see items below), we can propose complex products with low NRC, excellent feasibility and repeatability in both metal & ceramic materials and reduced lead time.

OSE R&D Development


Thanks to our R&D design office, metal & ceramic additive manufacturing machines and experience in space instrumentation and satellite system, we are developing nano/microsatellite structures (from 3U to 12U).

Our objectives is to provide you with complete payloads or specific components, designed for yours needs and outstanding characteristics. Our systems will give you priceless information on your observation missions: from agriculture, infrastructure, forestry to specific mapping.

  • Ultra stable and optimized optical systems
  • 3D printed mirrors and structures
  • Innovative solutions for thermal & mechanical performances
  • Parametric design for custom-made applications
