Forensic analysis of barometer data – the forensic use of air-pressure-based altitude measurement
In addition to satellite-based positioning, many drones use a barometric altitude sensor, which determines the relative flight altitude based on the surrounding air pressure and often provides more accurate readings than an altitude measurement based solely on GPS.
This data can serve as a valuable reference, independent of GPS altitude measurements, particularly when determining the actual flight altitude at a specific point in time.
Why LanCologne?
Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.
The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.
Our services
We analyse available barometer data and use it to verify and supplement the GPS-based altitude reconstruction of a flight.
Typical areas of application
This is how a barometer data analysis is carried out
Once the data has been backed up, available barometric readings are extracted and compared with the altitude reconstructed from GPS data. Any discrepancies between the two data sources are documented and, where possible, explained.
Why is the analysis of barometer data relevant in a forensic context?
As barometric altitude measurements can, under certain conditions, be more accurate than GPS-only altitude measurements, they help to provide a more reliable overall indication of the actual flight altitude.
Significant discrepancies between the two measurement methods are investigated in detail in order to rule out any possible measurement errors or tampering.
