Automatic rotator tilter system


The Comrod family of CAPAS® Automatic Payload Alignment Systems are designed to meet the challenges faced by public safety, defence and demanding industrial users. CAPAS® systems enables quick and effective deployment of communication or sensor assets in extreme environments without exposing personnel to unnecessary danger.

The CAPAS-RT Rotator Tilt System accomplishes this by allowing computer controlled tilt and rotation for payloads. The compact design allows the system to be used in a wide range of applications, and the rotator itself does not require a rotary joint for continuous rotation.

The powerful drive system coupled with the integrated magnetic compass ensures fast and accurate positioning. CAPAS-RT supports both closed loop and open loop alignment, or a combination of both.  In closed loop alignment mode the system is controlled by a radio transceiver to optimise received signal strength and minimise bit error rate. In open loop
mode the system can utilise input from the Comrod TCT Planning System for quick initial positioning. Closed loop feedback from the radio can then further optimise the alignment within a fraction of a degree.

The CAPAS-RT is fully rugged per MIL-STD-810, and is suitable for a wide range of deployable masts, including Comrod TM, LMT and ULM series.
