Main Space related products, services and projects

  • Custom Space Electronics

    The core skills within Réaltra are focussed on the design, build and integration of custom electronic hardware and software solutions for a range of space applications including on-board sensor monitoring and data processing and heater or actuator control. These space applications include embedded intelligence for local data pre-processing, actuation or for transmission of data to an on-board computer and/or to a telemetry stream. The custom design is married with the capability of Realtime to manufacture electronic assemblies to IPC, J-STD & ECSS standards.

    Réaltra is responsible for the design, development, integration and test of PLATO Payload Interface Unit (PLIU) for OHB.
  • Integrated Electronic Systems

    Réaltra has built on the experience of its staff to both ruggedize and integrate COTS electronics using in-house & licensed technologies for applications in the space environment. Our experienced team have a full range of the engineering expertise and manufacturing capabilities to design, develop and deliver high performance space electronics hardware solutions for safe and reliable operation in the extreme conditions of launcher and space missions from LEO to Deep Space.

    Réaltra is responsible for the design, development, integration, and test of the Ariane 6 launcher Video Telemetry Kit for ArianeGroup.

  • COTS Modular Avionics

    Réaltra is developing its own IP around an innovative concept for future spacecraft modular avionics systems based on a network of nodes where each node provides a specific function. The Réaltra concept is based on lowering the overall costs of avionics systems as each node would consist of a standardised design. The avionics nodes are being designed with improved FDIR performance to meet the spacecraft mission requirements using low-cost COTS based avionics systems. The commercial benefit with the proposed development is to provide an order of magnitude reduction in the cost of avionics for future spacecraft.
