Sources and versions
Our local tools can read PX4 ULog, inventory fields and versions, and check that the source file remains unchanged.
JAGRION / DRONES AND MISSION DATA
Make mission data a basis for review.
When flight logs, timestamps and technical records disagree, knowing where to begin can be difficult. We develop tools that preserve sources and make gaps visible.
Scoped analyses and development pilots

Illustrative data
Start with what is actually available.
This invented example contains a log and a time field. The presence of a field does not yet establish its meaning.
- Log
- Demo A · synthetic
- Observed field label
- Time field
- Field meaning
- Requires documentation
Synthetic example · no measurement, fault detection or aircraft connection.
Technical analysis around your existing platform.
For manufacturers, integrators and operators reviewing logs after an update, comparing exports or clarifying documentation across suppliers. We agree the data scope and review criteria with your specialists.
OUR WORK
Each answer needs a documented basis.
Time and sequence
Event time and receipt time remain separate when both are documented. Missing timestamps are not filled with guesses.
Explanations and conditions
Research tools preserve multiple model-compatible explanations and their assumptions. A possibility is not an established physical cause.
The next check
The review identifies additional records or controls needed. We also state when the material cannot resolve the question.
AN AGREED ANALYSIS
A deliverable your specialists can examine.
Scope, data and deliverables are agreed before work begins.
- 01
Data map
Sources, formats, versions and missing fields.
- 02
Timeline
Documented sequence where the clock evidence permits it.
- 03
Working note
Observations, open questions and the next necessary check.
RESEARCH AND DEVELOPMENT
Existing tools. Explicit validation limits.
We have local log-reading and checking tools alongside synthetic tests of analysis methods. Version-specific field definitions and their connection to physical events remain under validation. This page does not provide aircraft control, certification or validated physical fault diagnosis.
START WITH THE QUESTION
What should your mission data help resolve?
Describe the task and file format. Please do not send confidential flight logs with your first enquiry; data access and handling are agreed separately.
