Improve the stability of drone flight

Customer Background

A commercial UAV manufacturer based in Shenzhen, specializing in agricultural spraying and aerial inspection drones. Their flagship model required stable flight attitude control under challenging conditions such as high-altitude winds and rapid takeoff/landing.

Challenges

• Strict SWaP constraints due to compact airframe design.
• Need for fast-response, low-latency attitude control under wind gusts.
• Cost-effectiveness was critical for competitive pricing.

GyroSens Solution

• GyroSens provided the GSACC301M MEMS triaxial accelerometer, paired with a compact attitude engine. Key features:
• Low power (<1W) and lightweight (<20g).
• Built-in vibration rejection filters to eliminate high-frequency noise.
• 1000Hz max output rate for real-time control loops.

Results

After integration, the drone demonstrated a 42% reduction in attitude error (RMS) during gusty conditions. Hovering accuracy improved to within ±0.5 meters. The client successfully launched the upgraded model into international markets and obtained FAA waiver support for beyond-visual-line-of-sight operations.
