Réaltra Space Systems Engineering, a division of Realtime Technologies Ltd. based in Dublin, Ireland, specializes in providing dedicated design and development engineering expertise for space electronics systems. Collaborating with Realtime Technologies, Réaltra leverages its proven manufacturing capability for space applications.
Réaltra Space Systems Engineering experience
Since 2006, Realtime Technologies has been manufacturing, integrating, and testing electronic boards for data acquisition systems across a broad spectrum of past and upcoming space missions. This includes launch vehicles such as SpaceX Falcon 9, Vega-C, Ariane 5, and Ariane 6, re-entry spacecraft like SpaceX Dragon, Space Shuttle, IXV (Intermediate eXperimental Vehicle), and Boeing CST-100, space station components like ALCS (Advanced Closed Loop System) and PLDR (PayLoad Data Router), and sub-orbital vehicles like SpaceShipTwo and VSS Unity Spaceplanes. Réaltra is currently designing and building the Payload Interface Unit (PLIU) on the PLATO spacecraft and has a number of ongoing projects in the area of AI / ML for small satellites.
The HD camera
Within the SALTO project, dedicated to conducting hop tests for Europe’s first reusable launcher, Réaltra’s team is actively developing an HD camera. This camera, designed for the initial hop test, features a global shutter, enabling an impressive 100 frames per second (fps). In comparison, traditional cameras typically operate within the range of 24 to 60 fps. The newly developed HD camera is poised to deliver live high-definition images of the hop, allowing for post-analysis with exceptional image quality for both the structure and subsystems during the hop. Utilizing H.265 compression, the HD video camera ensures efficient transmission of high-definition images over low bit-rate RF transmitters.
Traditional cameras compared to HD cameras for space launch
Space launcher HD cameras differ from traditional cameras due to their specialized features tailored for space missions. These cameras incorporate global shutter technology to capture rapid movements without distortion, boast higher frame rates for detailed analysis, and prioritize durability to withstand extreme conditions in space, including temperature variations and radiation exposure. Their lightweight design, specialized optics, and mission-specific features contribute to their adaptability for space applications. Traditional cameras may prioritize other factors over weight reduction.

Additionally, space cameras often employ advanced data compression techniques, such as H.265, to efficiently transmit high-definition images over low bit-rate RF transmitters. These characteristics collectively distinguish space launcher HD cameras as high-performance, reliable tools specifically engineered for the unique challenges. They undergo rigorous testing, including thermal vacuum, vibration and EMC, to ensure they can function reliably in these environments.
