About Emxys

Emxys (Electronics and Mechanisms from Extreme Systems) is a research-driven company founded in Valencia, Spain, specialising in high-performance electronics and embedded systems for space applications. The company designs and manufactures electronics for space instruments, data acquisition, and control systems, delivering solutions for both space and terrestrial markets.

Emxys's flagship product line centres on the ODALISS nanosatellite platform — a complete, high-performance CubeSat bus with optical communications capability. The ODALISS architecture is built around a high-speed, multi-protocol logic bus that allows data-intensive payloads to be connected in a scalable, modular configuration. This design philosophy enables researchers and mission operators to integrate the most demanding scientific instruments without compromising data throughput.

Beyond the complete platform, Emxys offers the individual subsystems as standalone products: the ODALCOM optical transceiver for infrared high-data-rate links, the DIPP and OBC embedded computers for onboard processing, the PDCU power distribution and control unit, VHF/UHF TTC transceivers, triple-junction solar panels with integrated sensors, and an SDR-based ground station covering UHF, VHF, and S-band frequencies.

Emxys has supported European and international space missions including work with Arianespace and UPMSat-2. The company holds AS 9100 aerospace quality certification and operates as part of Spain's growing commercial space sector.
