Technical Reliability for your In-Orbit Systems
NEXEYA designs, produces, integrates and commissions satellite components and the associated ground resources in the fields of telecommunications, earth observation, science, and navigation, from one-off prototypes to whole constellations such as IRIDIUM NEXT.
For more than 20 years, NEXEYA has been designing, manufacturing, testing and integrating aluminium and carbon composite structures for the space industry. All of our production means are compatible with 3m x 2m panels. NEXEYA implements cutting-edge technologies: stable aluminium or carbon skins, dual density honeycomb, bonding of doublers, embedded fittings and heat pipes, flat or curved shapes, Z306 or PU1 paint, etc. The majority of its processes are carried out internally (drape forming of skins, construction of sandwich panels, firing, trimming, drilling, bonding of inserts, machining, finishing and equipping of panels, static tests, etc.) NEXEYA has established a strong partner network for non-destructive testing and processing of materials.
NEXEYA can manufacture all sorts of panels, from standard panels to stable carbon structure panels for Earth observation or science instruments. Our production capacity lets us develop one-off products or prototypes, as well as meeting mass production requirements for constellations such as Globalstar 2, O3B Network, or IRIDIUM NEXT.
NEXEYA designs, manufactures, tests and integrates satellite and instrument thermal control subsystems. The most comprehensive of these subsystems comprise: SLI’s, MLI’s, secondary support structures made from kevlar or aluminium, Sunshield, RF screens, SSM, OSR, thermistors, heaters, heat pipes, fluid loops, SIGRAFLEX® or CHO-THERM® seals, etc.
The greatest stresses a satellite undergoes are thermal stresses, being subject to a very high thermal gradient (from -160°C in the shadow of the Earth to +150°C in direct sunlight). Thermal control systems thus play a major role in the service life of the satellite. NEXEYA can implement a wide range of processes compatible with project mission specifications (shadow edging, sun edging, atomic oxygen (ATOX) environment, use of titanium, etc.) and with the requirements of the major contractors in the Space industry.
Thanks to its stocks of materials and components, NEXEYA can guarantee good responsiveness and provide solutions to customer requirements and constraints. NEXEYA is able to offer everything from one-off qualification models to the mass production of recurring models, both for the telecommunications field and for Earth observation and science.
NEXEYA is a European leader in the design, manufacturing, testing and integration of embedded harnesses for satellites and launchers. NEXEYA is capable of electrically and mechanically designing instrument harnesses (500 connection points) to harnesses with the most complex payloads (35 to 40,000 connection points).
NEXEYA’s expertise has been certified (ASF N° 13-69) by the CNES (the French government space agency) for all of its internal processes implemented in the development of space wiring systems. NEXEYA manufactures the Vehicle Equipment Bay harnesses for Ariane 5. This bay represents the heart of the launcher, centralizing all of the equipment interfacing with the propulsion control-command systems and monitor the payloads.
NEXEYA also manufactures harnesses for satellites in various fields: TV/radio/Internet communications, Earth observation and science, navigation, radar and satellite imagery, and satellite constellations. Thanks to this diversity of applications, NEXEYA has gained extensive experience in the implementation of its processes and the inherent design constraints.
NEXEYA has 1,000m² of ISO 8 cleanrooms and two ISO 5 laminar flows integrating all types of space systems at the appropriate level of cleanliness.
