Keep the payload on target while the platform moves
Cameras, EO/IR sensors and antennas on drones, vessels and vehicles are constantly disturbed by vibration, wind, waves and manoeuvres. A stabilization controller measures these movements with an IMU and counteracts them with its motors in real time.
AMCORIS supplies Epson 6-axis IMUs and supports you from sensor selection and evaluation to integration into your stabilization system.
QUICK ANSWER
Which IMU specs matter for stabilization?
Angular random walk (gyro noise) decides how smooth the stabilized image or beam is. Bias instability decides how well a pointing angle is held over time without drift. Output rate and latency limit the bandwidth of the control loop, and size and weight matter on small gimbals. The Epson M-G366PDG and M-G370PDG combine 0.08 and 0.06 °/√h ARW with up to 2 kSps in a 10 g package.
THE STABILIZATION LOOP
How an IMU keeps the payload steady
The IMU sits on the stabilized part of the gimbal or platform and measures every remaining movement. The controller uses this data to drive the motors so that the payload stays level and on target.
1
Sense
Angular rate and acceleration on three axes, at up to 2000 samples per second.
2
Estimate
Attitude from gyro and accelerometer fusion, with gravity as the level reference.
3
Correct
Motor commands counteract the disturbance before it reaches the payload.
4
Hold
Low bias instability keeps the pointing angle stable over minutes and hours.
Gyro bias instability in °/h (typ.). Shorter is better.
