Modern satellites generate massive data volumes (Earth-observation imagery, radar, telemetry). Traditionally, raw data is sent to centralized cloud data centers for processing – causing delays, high bandwidth costs, and reliance on non-European cloud providers.
This use case shows how the EMDC (Edge Micro Data Center) enables high-performance processing directly at satellite ground stations. By moving compute to where data is received, CAPE supports faster decisions, lower latency, and improved operational efficiency for space applications.
Key Challenges in Satellite Data Processing
- Latency: Time-critical use cases (disaster response, maritime surveillance, environmental monitoring) suffer when processing is remote
- Bandwidth costs: Sending raw datasets is expensive; only a fraction of the data may be relevant after processing.
- Scalability: Data rates vary by satellite pass and mission phase, requiring elastic infrastructure
- Security & sovereignty: Sensitive Earth-observation/government data must stay under European control and meet regulatory needs
- Energy efficiency: Continuous cloud processing increases cost and carbon footprint
Concept: Processing at the Edge
CAPE deploys EMDC systems at ground stations, so data is processed immediately upon reception – rather than forwarding raw streams to the cloud. This enables:
- Filtering/decoding raw payload data
- Local image generation and enhancement
- AI-based analysis at the edge
- Sending only high-value results to the cloud
High-Level Processing Flow
Satellite data processing typically follows three conceptual stages:
- L0 – Raw data processing: demodulation, error correction, frame extraction, synchronization/cleanup.
- L1 – Data reconstruction: conversion to structured outputs (calibrated images, geolocated measurements).
- L2 – Information products: science-ready outputs (object detection, indicators, change maps).
The EMDC accelerates these stages with GPUs, FPGAs, and AI accelerators, enabling real-time or near-real-time processing.
Role of the Edge Micro Data Center (EMDC)
The EMDC platform provides:
- High-performance compute close to antennas
- Hardware acceleration for signal processing
- AI inference at the edge
- Secure local storage
- High-speed networking for data distribution
The infrastructure is modular, ground stations can scale capacity dynamically depending on satellite passes or mission requirements. This[PR1] enables “processing-on-demand” without over-provisioning hardware.
Example Applications
Why Edge Processing Matters
Processing satellite data at the edge delivers:
- Faster reaction time
- Lower transmission costs
- Improved data security
- Reduced cloud dependency
- Lower CO₂ footprint
- Sovereign European infrastructure
Summary
CAPE and it’s scalable Cloud-Edge hardware Platforms enable a shift from centralized cloud processing to ground-station edge processing, delivering faster insights, better scalability, stronger security, and cost savings for next-generation space missions and Earth-observation services. The work targets scaling this pipeline to very high data rates with resilient orchestration to improve autonomy and bandwidth efficiency.
