UAV Radar Altimeter SRR 308

Altitude estimation challenges for UAVs

• Barometer: Measures altitude above sea level (MSL), not ground level (AGL)
• GPS: Limited vertical accuracy and signal-dependent
• IMU: Subject to drift without external references
• LiDAR/ultrasonic: Performance affected by weather, vegetation, and reflective surfaces

Areas of application

• Collision Avoidance
• Landing Assistance
• Terrain Following
• Flight data logging

Benefits

• Robust and reliable across diverse flight and weather conditions
• Stable height estimation from 1m up to 150m
• Easy installation and operation for various drone models
• No calibration or complex data fusion required
• Detection-based filtering for consistent altitude accuracy
• Provides reliable height-over-ground information

Interfaces

The AUMOVIO SRR 308 includes an optional DRONECAN bus interface. Additional interfaces can be added via converters. Custom software, hardware, and housing adaptations are available, making the SRR 308 suitable for complex measurement tasks.
