Getting Started

Fixing infantry guns after maintenance, or after dyeing black is quite arduous. Previously, there were several methods and tools to calibrate guns accurately and modernly. However, they require the construction of expensive infrastructure, resulting in high correction costs in the low field of combat.

Therefore, the method of calibrating guns with target shooting is still applied commonly, but it consumes an enormous amount of ammunition. The calibrators must-have shooting skills, and natural, weather, and climatic conditions.

From that fact, the technical staff of VINASHOOT has successfully researched and manufactured the VNS-F75 System to improve the quality of gun correction.

What Is the Method of Gun Calibration?

In the military, the calibration device includes a microcomputer control device, a high-speed camera device, a target distance measuring device, and a projectile calibration device respectively connected to the microcomputer control device.

The electromagnet group is available along the axial direction of the main body. The electromagnet group includes at least three electromagnets, and the manufacturer evenly arranged the electromagnets along the circumference of the gun barrel.

The calibration device calculates the azimuth and distance of the target point deviating from the recognition point, and through the control of the microcomputer control device. It makes the electromagnet group produce a specified direction and magnitude of the resultant force acting on the projectile, changing the movement trajectory of the projectile and making the projectile wider.

Besides, the trajectory is calibrated by controlling the electrification of the electromagnet group to be turned off at a specified time. So, the flight speed of the projectile can be further increased, making the gun’s range and shooting power stronger.

Methods of Gun Calibration

The tool applies the principle of using optical sights to position the line from the gun barrel to the reference point on the calibrated target. Then aim through the viewfinder of the gun. If this line-of-sight deviates from the reference point on the calibrated target, move the part of the reticle so that the line of sight through the viewfinder is correct on the reference point on the target. We could adjust the gun to the correct aim.

To implement the above correction method, besides using the standard glasses for locating the muzzle line, there are some details:

• Calibration is made on the base and rack of the K53 machine gun.
• Fitting for fitting standard glasses to the gun barrel end
• Vam and wrench to calibrate the organ of sight.

When making adjustments, calibrate the gun holder firmly on the rack and fit standard glasses on the barrel end. One person looks through the standard glass, announces the result so that the second person adjusts the range and direction (on the calibrated rack) to ensure that the cross point on the glass coincides with the cross on the calibrated target.

Fix the gun, aim through the viewfinder on the calibrated target, if the line-of-sight deviates from the reference point on the calibrated target, use vam (viewfinder correction) and wrench (fly head correction) so that line of sight passes through the reticle to coincide with the benchmark on beer is fine.

Thanks to the line-of-sight correction tool, the gun correction efficiency increases up to 400%, the gun rate after correction is satisfactory about 85-90%, reduces the ammunition consumption by 65% ​​, and is convenient to deploy the effective ground correction. The production cost of the product is very cheap because it takes advantage of many existing levels 5 types of equipment in the unit.

How VNS-F75 System Works for Gun Calibration?

VNS-F75 system is developed on the basis of Audio signal processing technology with SS75 LOMAH Sensor centered on the sensor system. It comes with a special algorithm to calculate the touch point on the target with ultimate accuracy base on the electronic shooting scoring function.

The system includes a gun rack frame, desktop computers/laptops with VNSS software installed. In the system, we have gun adjustment software, screens, wires for gun owners to observe and manipulate directly with the computer. The software has built-in adjustments for standard infantry guns. Accordingly, the calculation and management of the direction and range angle on the top of the fly’s head become simple. Calibration gunners only need to simply follow the instructions on the software.

When applied the system allows to determine the touchpoint of the bullet track, calculate, and notify the average touchpoint for gun calibration. The system displays the shot results and evaluates the correction amount intuitively. Users can record and store gun calibrations for comparison.

Thanks to the preeminent features of the VNS-F75 system, VINASHOOT’s R&D team has exploited and served for calibrated shooting, an inspection of infantry guns after repair and maintenance, contributing to ensuring outstanding quality of firearms. Our system has an aim of soldiers serving for training and combat readiness of units in the Military.

VNS-QA is a system that allows high-speed, accurate calculation of each shot, management of each gun, each bullet checked in the production batches of the military gas factory. It also assists databases that help analyze and manage the quality of weapon manufacturing systems.

The LOMAH sensor system SS75 is the central element of the system, below and in front of the test target permanently mounted on a metal frame. It detects and calculates the touchpoint through the signal the bullets generate when flying through the sensor frame. We calculate the sensors with temperature compensation to give results with millimeter accuracy.

The VNS-QA system makes making gun adjustments simple. By applying this system, the preparation for the shooting session is easy as a piece of cake without the requirement of gunners with excellent shooting skill. This feature is vital since a force of skill gunners is not always available. In addition, the safety is improved and the gun adjustment is increased by 500% compared to the traditional gun adjustment method due to solving the bottleneck in the entire gun adjustment process chain.
