RWS
MAIN FRAME ASSEMBLY

-2 COMPONENTS (FRAME AND SLIP RING)

-The Frame constitutes upper part of the Main Frame Assembly that rotates 360° on a tubular slip ring. The azimuth axis rotates at a speed of up to 80° per second. The Frame contains the Azimuth Servomotor with Main Azimuth Gear. The Frame also houses the servo amplifier for all four servo motors, azimuth and elevation encoder, stabilization gyros, azimuth release mechanism and transport lock.

A single press of +/- key will increase or decrease range in 10 meter increments.

The range scale is from 100 meters to 2200 meters. The default range on power-up is 700 meters.

RWS FCU CONTROL GRIP SPEED

The maximum Control Grip (CG) speed may be selected in the range 10 – 100% in steps of 10%.

RWS SENSOR CONTROLLER SOFTWARE WHERE IS IT LOCATED AND WHAT IS IT FOR?

Located in the Sight Servo Assembly Handles communication between the Fire Control Unit and the sensors as well as controlling the cocking actuator

RWS SENSOR CONTROLLER SOFTWARE SENSORS CONTROLLED BY THE SENSOR CONTROLLER?

-Visual Imaging Module (VIM) -Thermal Imaging Module (TIM) -Small Tactical Optical Rifle Mounted (STORM) Laser Range Finder (LRF) -Low Ammo Sensor: which is located on the LSSA ammo box but a wire runs to the SSA to indicate low ammo warnings, don’t place an ammo can in the ammo box as it will not register low ammo warning -Inclinometer: used during ballistics compensations and measures the roll and pitch of the line of sight relative to the horizontal plane

RWS SERVO CONTROLLER SOFTWARE WHERE IS IT LOCATED AND WHAT IS IT FOR?

The Servo Controller is stored inside the Fire Control Unit The Main purpose of the Servo Controller is to control and move the servo actuators/motors, based on the CG movement and control messages from the Fire Controller.

RWS SERVO CONTROLLER SOFTWARE WHAT DOES THE 4 AXIS SERVO SYSTEM CONSIST OF?

1. Elevation and Azimuth axis for TIM and VIM 2. Elevation and Azimuth axis for Weapon System (WS)

RWS SERVO CONTROLLER SOFTWARE WHAT DEGREE OF MOVEMENT DOES THE SSA HAVE?

± 10 degrees in the azimuth axis +3/-15 degrees in the elevation axis.

RWS WHERE ARE THE FIBER OPTICAL GYROS (FOG) LOCATED? AND WHAT DO THEY DO?

In the Main Frame Assembly One measures the main frame azimuth axis, and one measures the main frame elevation axis
