Public research on sensor degradation.
Inspection bodies, regulators, standards groups and peer-reviewed journals have documented for years that sensors lose performance in service, long before any fault is reported. These are the sources we cite. All of it is third-party and openly available.
18 sources in five groups. Each link opens the original on the publisher's site. Corrections and additions to info@obsurver.com.
Field evidence
Inspection bodies and test organisations measuring vehicles that have been on the road for a while.
-
ADAS not always reliable in long-term operation
An inspection body states plainly that assistance systems cannot be assumed reliable over the vehicle's life.
-
Long-term ADAS reliability, analysed
The detailed analysis behind the press release: how assistance systems degrade in long-term operation.
-
Minimally misaligned ADAS sensors
Study on how even small sensor misalignment affects the behaviour of driver assistance systems.
-
Bodywork industry on the DEKRA findings
The repair trade's perspective on misaligned sensors after collision repair.
-
ADAS may drift after normal use
Testing indicates assistance systems can drift out of calibration in everyday operation, without any collision.

IMU degradation in industrial robots
Peer-reviewed study: robot sensors wear gradually and fail without warning, with no systematic monitoring across the signal chain.
-
Sensor drift in agricultural autonomy
Heat, humidity and dust degrade field sensors; the only mitigation today is manual recalibration.
