Model Rocketry
From Estes to high-power, AltimeterThree captures every second of your rocket's flight. Track altitude, velocity, acceleration, and precisely timed recovery events — then analyze it all in FlightLab.
Why rocketeers love AltimeterThree
Model rocketry demands precision timing and reliable flight data. AltimeterThree uses a high-resolution 19-bit barometric pressure sensor with precision to the nearest foot, combined with a 3-axis accelerometer that captures acceleration up to 24G.
- Maximum altitude to the nearest foot
- Peak velocity and acceleration curves
- Motor thrust duration timing
- Ejection delay and altitude analysis
- Descent rate monitoring for recovery optimization
- Total flight duration from launch to landing

Key metrics for rocketry
The rocket flight mode automatically identifies and timestamps critical flight events:
- Burnout detection — Precise motor cutoff timing
- Apogee marking — Exact peak altitude with timestamp
- Ejection analysis — Delay timing and deployment altitude
- Descent profiling — Drogue and main chute deployment tracking
