Managing Satellite Telemetry at Scale: Eutelsat OneWeb + InfluxDB

When your constellation spans 600+ Low Earth Orbit satellites and every spacecraft produces over 50,000 individual telemetry values, your data infrastructure either keeps up or becomes the bottleneck between you and mission assurance. Eutelsat OneWeb found that general-purpose log platforms weren’t built for what spacecraft actually produce — and set out to find a better foundation.

In this case study, you’ll see:

• Why Eutelsat OneWeb outgrew Elasticsearch and what broke down at LEO constellation scale.
• The guiding principles they used to evaluate a new telemetry platform: scalability, cost efficiency, flexibility, automation, and openness.
• How InfluxDB now ingests more than 1 million data points per second and supports 15 million unique series across the constellation.
• What the team is building next — including ML pipelines for proactive anomaly detection and fleetwide trend analysis.
