2024 Observability Report
Navigating the Complexities of Telemetry in a Rapidly Evolving Industry
Executive Summary
The propulsion industry stands at a critical juncture, facing unprecedented challenges in managing the vast amounts of data generated by increasingly complex engine systems. From liquid rocket propulsion to air-breathing hypersonic engines, maintaining real-time telemetry integrity and ensuring comprehensive test observability are essential for mission success. This report, based on a comprehensive survey of 100 aerospace engineering professionals across propulsion development, satellite, defense, and commercial spaceflight, explores the current state of telemetry and observability in propulsion testing, highlighting key trends, challenges, and engineering-driven solutions.
Our research reveals an industry grappling with the intricacies of building and maintaining robust observability systems capable of handling high-frequency sensor data, transient combustion instabilities, and the increasing integration of AI-driven diagnostics. While many organizations have historically relied on bespoke in-house solutions tailored to specific propulsion test environments, the landscape is shifting. The data points to a growing recognition of the risks associated with fragmented internal systems, delayed anomaly detection, and the escalating complexity of next-generation engine architectures. In response, there is an emerging openness to scalable, high-performance observability platforms that enhance test efficiency, improve fault isolation, and provide real-time insights that drive faster iteration and safer, more reliable propulsion systems.
