Radiation Tolerant Space Compute Intensive Module

Product Status: Active


QLS1046-Space is a Space Radiation Tolerant Compute Intensive integrated solution.
It embeds:
• A Quad ARM® Cortex®-A72 Microprocessor (LS1046) running at up to 1.8GHz and bringing 30K DMIPS computing capabilities, integrated packet processing acceleration, high speed peripherals including 10 Gb Ethernet, PCIe® Gen3, SATA 3.0 and USB.
• A 4GB DDR4 memory connected to the Space Microprocessor

QLS1046-Space Flight Models are Radiation Tolerant & Space qualified.

Typical End Applications

QLS1046-Space is a common computer platform that can serve many applications requiring compute intensive capabilities in Space. See examples below.

QLS1046-Space is also very useful for platforms in Space and embedding Artificial Intelligence, as it can run deep learning AI algorithms for image processing in Space for example. It brings then the technical benefits of pre-processing information at the edge and reduce the downlink bandwidth when sending to the ground.

On top, and naturally brought from the product form factor and integration, QLS1046-Space is particularly interesting for project teams willing to reduce their development time, platform size and bill of material.
Typical End applications:
• Communication Satellites / Constellations – Requiring AI / Security
• Human Mission Exploration & Science Missions
• Early Warning, Observation Satellites - Security / Automated situation detection & awareness / AI
• Defense In Space
• High bandwidth Space Observation
• Meteorological Satellites
