Drones & Quadcopters
From tiny whoops to heavy-lift quads, AltimeterThree gives you independent altitude data for every flight. Verify your flight controller's readings and build a complete flight history.
Independent altitude verification
Your flight controller already tracks altitude — but AltimeterThree provides independent verification using a 19-bit barometric pressure sensor that detects changes of less than one foot. Perfect for validating FC data or maintaining records for regulatory compliance.
- Maximum altitude to the nearest foot
- Complete altitude profile throughout the flight
- Flight duration with automatic detection
- Unlimited flight history in the cloud
- Launch location shown on a map
- Export to spreadsheet for records
Works with any multirotor
AltimeterThree weighs just 9.9 grams and measures 49 × 18 × 14.5 mm — small enough to fit on almost any drone without affecting flight characteristics.
FPV racing
Track your altitude changes during races and freestyle sessions.
Aerial photography
