Time-series data software package built for aerospace R&D and flight testing. Combine data from files and telemetry, analyse with precision and validate requirements based on advanced insights.





Telemetry in aerospace often starts as large data files. MarpleDB is engineered around file-originated measurement data.
Use built-in plugins for the most popular file types such as MDF/MF4, CSV, MAT, ROS/Rosbag and many more.
Combine on-aircraft and telemetry data by using our realtime datastreams.
Use our SDKs to automate data loading and reduce manual effort.
Subdivide flight test data into distinct flight phases, making it easy to analyse each stage individually and switch between them seamlessly.
Surface anomalies fast with a unified dashboard that spans all your data and spot outliers from any angle in your test campaign.
Visualise CAS alerts, event markers, status messages, A/P commands and more in a single, clean timeline.
Tag specific timestamps in your test flights so the whole team can revisit and discuss them in debrief.


Visualise your craft's orientation with a 3D model that reflects pitch, roll, and yaw throughout the test.
Replay engineering data with an integrated PFD view to make debriefs clearer and more intuitive.
Overlay mission maps, test cards, FIRs, SIDs, STARs and more directly on your GPS track.
Visualise and assess flight data within defined airspace regions.
Discover how Aerodelft is making liquid hydrogen-fueled flight possible by using Marple for precise and reliable analysis of test flight data and accurate reporting to flight authorities.
Marple DB is purpose-built for high-frequency telemetry data, handling measurements from 1Hz to 10kHz or more. Optimized for hundreds or thousands of sensors, it ensures fast, ad-hoc querying through a PostgreSQL layer enhanced with clever data segmentation for seamless scalability.
Effortlessly transform time series data from files into a performant database structure with Marple DB. Retain file metadata within the database, use standard plugins for common data flows, or fully customize the setup to match your unique needs.
Marple DB connects seamlessly with Marple Insight for effortless data exploration. Its data structure is designed for optimized querying, ensuring smooth workflows. While tailored for Marple Insight, it also integrates easily with other tools in your stack.
Marple DB supports 10 standard plugins for popular file types and enables you to create or modify plugins to suit your needs. Customize and configure data flows for various file types, ensuring smooth integration with your telemetry data sources.
