At present JSC "Design Bureau of Transport Machinery" (Omsk) is a pioneer in the development of heavy flamethrower system (TOS) TOS-1A, "sun", which is designed to provide fire support to infantry and tanks, the defeat of the enemy, open and covered fire positions in a variety of offensive and defensive combat, as well as the decommissioning of light armored vehicles and vehicles. The system includes a fighting machine BM-1. "sunshine" capable of hitting enemy targets at ranges from 3.6 to 6 kilometers (depending the type of missile).
Figure 1 — Option placing the article on the ABAC-KTNTS BM TOS-1A (object 634B).
Fighting vehicle BM-1 is a multiple launch rocket systems (MLRS) on tank chassis of T-72A. Fighting machine (BM) is used to place Nursi and start at designated targets.
BM-1 is equipped with a rotating platform with a swinging part in the form of a package of 24 tube guides for missiles with power servo drives and fire control system, placed on the chassis of a main battle tank T-72A. Guidance swinging of PU on the target in the horizontal and vertical planes produced power servo drives with a laser rangefinder and ballistic computer. The most important condition for maintaining the combat readiness of TOS-1A and ensure the effective management of its fire is the exact orientation of PU and Surveying binding.
The fire control system TOS-1A includes an optical sight, laser range finder periscope 1D14, tilt sensor, trim PB2.329.04 (electrical, Pendulum) and specialized electronic digital computer system with sensor equipment MO.1.01.01.03M2. A laser range finder distance to the target are determined with an accuracy of up to 10 m The data is automatically entered into the ballistic computer calculates the required elevation launcher. The angle of heel and trim package guides captured automatically and takes into account the calculator. TOS-1A incorporates the device orientation — giropolukompas HPA-59.

"NPO" Progress "offers a comprehensive solution to upgrade TOS-1A, and the use of the product ABAC-KTNTS comprising: a laser designator c to measure the distance to the target, up to 1.5 meters, forced a precision inertial measurement unit, which serves as high-precision topographic location with an accuracy of 0.7 PDE, gyrocompass and girokursoukazaetlya, navigation .
Product ABAC-KTNTS turns TOS-1A as an independent reconnaissance and strike complex. It should be noted that the adopted today in service of the Ministry of Defense of Russian mobile navigation systems and geodetic topoprivyazchiki have the precision parameters of PDE 2
The technical proposal relates to the fire control system, including the gyrocompass girokursoukazatelyam, orientation and stabilization systems PU.
The essence of the technical proposal is shown in Figures 1 and 2. The composition of the BM TOS-1A (object 634B) product introduced ABAC-KTNTS. To improve the accuracy and launch NURS TPU BM placed on inertial measurement unit (Figure 2), which also serves as for precision measurements BM azimuth, pitch and roll, and perform the function gyro, girokursoukazaetlya and navigator in the nomination of BM to the start position (SP).
Technical Proposal for placement on the ISS TPU BM-1 TOS-1A refers to methods for controlling vibrations of aiming launcher MLRS combat vehicles. The proposed technical solution, the measurement of the amplitude and frequency of vibration of aiming the weapon is carried out using high-precision built-in accelerometer inertial measurement unit (IMU) articles of ABAC-KTNTS. The measurement results are processed in the integrated unit TSBUN central computer in real time. Information about deviations of aiming device used for control intervals between shots, and the tension of the cable, or spring-torsional vibration isolators to change their stiffness in accordance with the specified characteristics of aiming in amplitude and frequency of oscillations as in the preparation of the shooting, and in managing the fluctuations in the process of aiming a volley MLRS. Technical Proposal "RPA" PROGRESS "automates the process of measuring and recording vibrations of aiming in real time.
Improving performance characteristics of TOS-1A is also due to improved fire control system. In fire-control system introduced inertial measurement unit that is connected to the central control unit and navigation, Doppler speed sensors, and optical sight used as a laser designator.
It should be noted that the ISS can be used to determine the gyro horizon, which is designed to measure the angles of the BM in the automated systems of stabilization funds and arms control volley fire. The technical result — increasing the efficiency of missile systems by eliminating the dynamic error gyrovertical during firing. In the conduct of shooting switching devices turn off the system and horizontal correction gyrovertical converted into the free gyro mode. To do this, O horizon sensors are connected to the input of the amplifier through a horizontal correction switching devices whose inputs are connected to the output of the control device, and its entrance — to the output of the driver.
Product ABAC-KTNTS provide strategic autonomy war machine (BM), BM increase vitality and reduce training time volley with an arbitrary starting position by an autonomous topogeodesic binding and orientation of MB standalone installation estimates of fire and flight plan data (EDM and DPZ), the coordinates of aiming points , bespritselnogo guidance package guides.
The system of independent orientation, according to the technical proposal "NPO Progress" is the initial azimuth and navigation equipment, built-in central control and navigation (TSBUN) — initial fighting machine TOS-1A. After which the navigation system TSBUN continuously determines the location and orientation of the BM, the system displayed on the electronic navigation map displayed on the color display of the display device. After receiving the targeting of the laser pointer, a block of reception and transmission of data, the system also displays the range to the target and the direction of the race at the starting position (SP). At the starting position inertial navigation unit product ABAC-KTNTS defines specified angles pointing to the current position of MB. The system continuously determines the error of their angles with the current guidance. Drive guidance on these disagreements exercise guidance package guides. After a volley of BM can make protivoognevoy maneuver and change the joint venture. Preparation of a new salvo is the same way.

The laser pointer is used to measure distance to an object in a single measurement. The principle of operation of a laser range finder based on irradiati
on of the object stack of laser pulses and simultaneous accumulation of echoes, reflecting? Nnyh from the object. The number of laser pulses emitted in the stack and, consequently, accumulated echoes adaptively selected from 1 to 1024, depending on the reflectivity of the object, its size, weather conditions and distance to the object. Laser pulse repetition frequency of 5 kHz. Laser pointer has built a television camera, the lens of which is shared with at? Mnym channel rangefinder. Displayed on the display device in the form of a cross mark and the distance to the object. Image of the object and the underlying surface on the display items improved by image processing procedures.
Incorporated in the product ABAC-KTNTS technical solutions and software will greatly expand the functionality of the fire control system, stabilization, orientation and navigation TOS-1A, improve positioning accuracy for combat positions and reduce the available time for work that enhances the survivability BM TOS-1A .
