The IMU Was Excellent. The Image Still Shook.
Two MEMS IMUs with remarkably similar datasheet specifications were evaluated for a high-performance stabilization system. Both offered excellent bias stability, low noise, and impressive inertial performance. Yet one delivered noticeably better tracking, faster settling, and superior image stability. What caused the difference? This case study explores why latency, synchronization, bandwidth, and timing determinism often matter more than traditional navigation specifications when designing EO/IR, gimbal, antenna tracking, and UAV stabilization systems.
