# Exlumina > Exlumina is a space technology company that designs and operates GPU-powered orbital data centers for AI inference, scientific computing, and real-time data processing in space. ## Company Overview - **Founded**: August 21, 2023 - **Industry**: Space Technology / Orbital Computing Infrastructure - **Website**: https://exlumina.space - **Tagline**: Orbital Data Centers ## What Exlumina Builds Exlumina builds and operates satellites that function as data centers in orbit. Each satellite carries NVIDIA Vera Rubin GPU compute modules capable of approximately 50 PFLOPS of AI inference (NVFP4 precision). The satellites operate in Sun-Synchronous Orbit (SSO) at 500–600 km altitude and maintain 24/7 connectivity via SpaceX Starlink's laser-based inter-satellite link (ISL) network. ## Core Technology - **GPU Architecture**: NVIDIA Vera Rubin (Vera CPU ~88 ARM cores + Rubin GPU) - **AI Inference**: ~50 PFLOPS at NVFP4 precision - **GPU Memory**: 288 GB HBM4 at ~22 TB/s bandwidth - **Interconnect**: NVLink 6 at 1.8 TB/s chip-to-chip - **Orbit**: Sun-Synchronous Orbit (SSO), 500–600 km altitude - **Connectivity**: SpaceX Starlink laser inter-satellite links (24/7 uplink/downlink) - **Operating System**: TachyonOS — custom real-time operating system for GPU workload orchestration, satellite telemetry, fault detection, and autonomous operations ## Use Cases - AI inference on Earth observation and satellite imagery - Large Language Model (LLM) serving from orbit - Sensor fusion for defense and intelligence - Sovereign data processing in physically air-gapped orbital environments - Persistent autonomous AI agents operating without ground intervention - Scientific computing and climate modeling - Real-time maritime and air traffic monitoring ## Key Differentiator On-orbit processing reduces Earth-bound data transfer by up to 90%, transmitting only actionable results instead of raw data. Starlink connectivity eliminates the traditional constraint of brief ground station passes, enabling continuous data processing. ## Links - Homepage: https://exlumina.space - Technology: https://exlumina.space/hardware - Software (TachyonOS): https://exlumina.space/software - Missions: https://exlumina.space/missions - Company: https://exlumina.space/company - Careers: https://exlumina.space/careers - Blog: https://exlumina.space/blog - Contact: https://exlumina.space/contact - Request Access: https://exlumina.space/request-access - Full AI Knowledge Base: https://exlumina.space/llms-full.txt
