LRERIís  SERVICES (Continuation) 

C. Armoured Vehicles based Command and Control Systems (AVCCS)

LRERI proposes to develop AVCCS for new main battle tanks and armoured fighting vehicles upgrades. The computerized AVCCS assists MBT commanders to make faster, better and more informed decisions based on all relevant data from battlefield system, thermal, optic imagers and TV-cameras and AVCCS major subsystems such as Navigation Subsystem, Fire Control Subsystem, Armoured Vehicle Movement Control Subsystem, Laser Weapon Defense Subsystem.

Search and Fire Control Radar (SFCR)

Command and Control Facilities for
Fire Control Subsystem (CCFFCS)

LRERI proposes to develop CCFFCS for new MBT and armoured vehicles upgrades. These facilities are utilized for ballistic computation and normalization of stabilizer signals proportional to gun lead and elevation angles.
CCFFCS comprise: display and parameter input consoles, ballistic computer unit and use input information provided by signals from:
1)  sights:
     - range
     - guidance angles
2)  atmosphere parameter sensors:
      - air temperature
      - air pressure
      - wind strength and direction
3)  sensors:
      - turret position
      - gun position
      - roll, pitch
      - ballistic type
4)  projectile firing speed instrument (muzzle velocity system):
      - initial projectile speed.

Armoured Vehicle Movement Control Subsystems (AVMCS)

LRERI proposes to develop AVMCS in order to enhance vehicle mobility parameters using computerized control of  basic and auxiliary engines and a gear-box.
The subsystem includes: driverís display consoles, basic engine and gear-box control unit, auxiliary engine control unit, reversing gear control unit, movement sensors.
AVMCS provides:
    - test and display of basic and auxiliary engine parameters
    - computerized start and stop of basic and auxiliary engines
    - optimal fuel feed by computing the position of a control rack based on combined real road and engine parameters
    - computerized gear shift from downshift to upshift and vice versa
    - maintaining of auxiliary engine speed as dependent on the load
    - reversing gear control
    - duplicated control mode

Navigation Subsystem (NS)

LRERI proposes to develop NS for all types of armoured vehicles that can be applied for the purposes as set forth:
    - measurement of current coordinates of terrain, road speed and time by SNS GLONASS and GPS NAVSTAR radio signals in any place of the Globe, at any time and under any weather conditions
    - destination assignment for the commander himself and the personnel under his command (by using the radio link), measurement of the distance to this point of destination, deflection angle and time of arrival according to the operator's instructions
    - subordinate location polling
    - telecode reception-transmission
    - storage of 50 route places

NS consists of: commander's console, operator's console, control unit, navigator receiver, movement sensors, radio station.
