CAK

Digital Artillery Angle Meter

Purpose of CAK

The CAK system is one of the elements of a multi-level artillery fire control system and can also be used as a standalone device.

The CAK system, which includes a high-precision device, allows for highly accurate determination of the current slopes and inclinations of the bodies and barrels of self-propelled artillery systems, multiple launch rocket systems, tanks, towed artillery systems, and mortars relative to the true horizontal and vertical positions.

Tested in combat and used with dozens of artillery systems. Its effectiveness has been demonstrated by the results of combat operations.

Latest Technologies

The system is built on a unified platform, taking into account the requirements of modern warfare and using the latest information technologies:

• Use of modern sensors and embedded programming principles combined with MIL810 military protection standards.
• Resistance to software hacking and the effects of electronic warfare systems.
• IP68 protection against aggressive operating conditions and use in harsh external environments.
• Power supply from the onboard network (if available) and autonomous power supply (up to 48 hours).
• Inclinometer for operation with any installation tilt angles.
• Additional protection of individual components.

Advantages

Speed of Operation

Measurements and data processing are performed instantly (max. 5 seconds). This significantly reduces preparation time, speeds up aiming and, if necessary, allows the position to be changed more quickly after completing a combat task.

Hot keys (buttons on the panel) are available for working with different modes, with the ability to switch between NATO and USSR measurement systems.

Reduced Human Factor

Automation of measurement and calculation processes minimizes the risk of errors associated with manual scale readings, visual assessment of the spirit level position, and subjective assessment by the gunner-operator (poor eyesight).

Advantages

Resistance to Operating Conditions

The device can operate effectively in conditions where conventional mechanical systems lose their effectiveness:

• the gunner does not need to illuminate the side-level scale with a flashlight to read the indicators;
• in smoky conditions inside the turret after firing the gun;
• it is not affected by activated electronic warfare systems.

Additional advantages:

• stable readings without the need for constant recalibration;
• the ability to quickly check the correct installation of the system;
• convenient use in confined spaces or during rapid deployment.
