Stabilization is one of our specialties at Watson Industries. We have been involved with a large number of applications, from trains to cameras. The SMS is designed primarily for instrumentation: it stabilizes on the Bank (X) and Elevation (Y) axis so that the mounting arm with its payload will always stay level, regardless of the motions of the vehicle.

Our gyro-stabilized platforms are built around a rugged pan and tilt mechanism. This is a high resolution digital system uses the best wide bandwidth, low noise, solid-state gyros. The whole system is user configurable and can adapt to a wide range of payloads and requirements.

Watson Industries also provides custom systems for special requirements. Our system design is modular and configurable for economical and quick adaptation to a wide variety of hardware configurations. Of course Watson Industries’ excellent product support and applications engineering goes along with every product.
