Description
The stabilised horizon bar is the central component of the Stabilised Horizon Bar Reference System, which consists of the horizon bar and two fixed reference lights. The horizon bar is stabilised to <0.5°, based on reference to the true horizon, by an internal motion sensor (Inertial Measurement Unit, IMU) and a powerful servo actuator. It can follow the vessel’s roll motion up to ± 30°. Furthermore, the horizon bar aligns automatically to its horizontal position after installation; no interface to the ship’s gyro is needed.
The standard horizon bar light colour is green, to ensure compatibility with NVG mode, according to STANAG 1445, Stage 2. Other colours are available on request including multicolour LEDs. The light intensity can be dimmed in 65K steps, configured in eight or more user-defined levels, via the control system. The horizon bar’s rigid design is made in full body, seawater-resistant aluminium, which is optimised for performance in extreme marine environments.
System integrity and operational reliability is controlled by internal electronics, combining multiple sensors measuring temperature, humidity and electric current, providing 24/7 monitoring of the horizon bar’s status. In that respect, the HRB will show an upcoming malfunction before it actually fails. Easily exchangeable standard dry agent cartridges provide effective absorption of residual humidity. Nitrogen filling – as alternative mode of humidity control – is available as optional feature.
