Spire Global Partners with SATE on ESA-Supported Research Program to Advance AI-Driven Autonomous Constellation Operations

Key Terms

on-orbit edge computing technical

Computing hardware and software placed on satellites or other spacecraft that processes data in space instead of sending raw information down to Earth. It acts like a mini data center in orbit, performing tasks such as filtering, compressing, analyzing or routing sensor data close to where it’s collected. For investors, this matters because it can cut transmission costs, reduce delays, enable new real‑time services and change the economics of satellite businesses much like edge servers changed cloud-based internet services.

predictive maintenance technical

Predictive maintenance involves using data and technology to monitor equipment or machinery in real time, identifying potential problems before they cause failures or breakdowns. By predicting when maintenance is needed, it helps prevent costly repairs and downtime. For investors, it highlights how companies can reduce expenses, improve efficiency, and maintain reliable operations, which can positively impact financial performance.

onboard processing technical

Onboard processing is the ability of a device, vehicle or instrument to analyze and act on data locally instead of sending it to a remote server. Investors care because local processing can cut delays, lower ongoing data costs, improve privacy and reliability—similar to a car that makes safety decisions instantly rather than waiting for a call to a traffic center—and that can enable new features, reduce operating expenses, and affect regulatory risk.

time-to-failure technical

Time-to-failure is the measured or estimated interval from when a product, component, or system is put into use until it stops working or no longer meets required performance. It matters to investors because it affects replacement and warranty costs, revenue continuity, maintenance schedules, and the perceived reliability of assets—similar to knowing how long a lightbulb will burn before it needs replacing, which helps plan costs and operations.

• Funded through Italian Space Agency (ASI) and UK Space Agency (UKSA) subscriptions to ESA, the 18-month program aims to enable real-time onboard diagnostics and more autonomous constellation operations

VIENNA, Va.--(BUSINESS WIRE)-- Spire Global, Inc. (NYSE: SPIR) (“Spire” or “the Company”), a leading global provider of satellite data, analytics and intelligence, today announced a partnership with SATE to develop and validate an artificial intelligence system for real-time satellite health monitoring, anomaly diagnosis, and predictive failure analysis through STRAIDE, an 18-month research and development program funded through subscriptions to ESA by the Italian Space Agency (ASI) and the UK Space Agency (UKSA), with programmatic support from ESA.

As satellite constellations scale, operators are increasingly challenged to monitor system health across large, distributed fleets. STRAIDE is designed to address this by enabling earlier detection of in-orbit issues, reducing operational downtime, and extending satellite lifespan through predictive maintenance and automated diagnostics.

Through the program, Spire will contribute its vertically integrated satellite platform, onboard processing capabilities, and operational flight data, along with a ground-based hardware replica of its satellite systems. SATE will further develop and integrate CLUE, its AI-based diagnostic system designed to continuously monitor satellite “vital signs,” detect early warning signals, diagnose anomalies, and estimate time-to-failure for critical components. The system is designed to operate both onboard satellites and on ground, providing flexibility for satellite operators.

“As Spire’s satellite constellation grows in scale, the operational complexity of managing each asset demands a fundamentally different approach,” said John E Ward, Spire’s Senior Director of Research and Development. “STRAIDE brings artificial intelligence on-board for satellite autonomy – detecting anomalies earlier, anticipating failures before they occur, and freeing operators to oversee larger fleets with greater confidence. Ultimately, STRAIDE positions Spire to enable earlier intervention, improved system resilience, and more efficient fleet management at scale.”

Spire continues to expand its onboard processing and autonomous satellite operations capabilities. As an early adopter of on-orbit edge computing, the Company has deployed satellites with onboard processing capabilities since 2022 – enabling more advanced data processing and decision-making directly in orbit.

Over the course of the 18-month program, the partners will work toward a validated end-to-end demonstration of the system with the aim of informing how AI-driven diagnostics can be integrated into Spire’s satellite architectures – supporting more autonomous operations, improving fleet resilience, and reducing reliance on ground-based intervention as constellations continue to scale.
