Integrated navigation–information system

Integrated navigation-information system is an integrated strapdown navigation system based on high-precision accelerometers and closed loop fiber-optic gyroscopes. The system is based on a fusion principle in relation to the data of the integrated strapdown system with odometer, receiver of satellite navigational signals (SNS) GPS/GLONASS and barometric pressure receiver. Integrated navigation-information system has a modular system, which allows to get different variants of the system, mostly satisfying the Customer’s demands on measuring accuracy and mounting convenience.

Equipment allows to fulfill full-scale survey, navigation and orientation tasks of rocket and artillery troops at any time in any weather conditions regardless of SNS signals availability:
• Determination of current coordinates of the object on halt (firing position, concentration area) and when travelling;
• Determination of orientation angles of moving objects (azimuth angle of vehicle longitudinal axis, roll and pitch angles);
• Automatic determination by satellite navigation systems (SNS) GPS/GLONASS signals of current universal and local time adjusted by time zone;
• Display of values of current coordinates and altitude of ground transport vehicles (GTV) by the operator’s option (survey or rectangular) as well as velocity, angle of vehicle longitudinal axis, current time on the indicator panels and onboard computer monitor;
• Display of navigation and survey information on digital terrain maps as well as self-position, coordinates and altitude of standing point on onboard computer monitor.

Composition of integrated navigation-information system:
• Tablet computer with navigation software (on the Customer’s demand);
• Inertial navigation measuring unit based on high-precision accelerometers and fiber-optical gyroscopes;
• Data control and processing unit;
• Satellite navigation unit (SNU) with digital atmospheric pressure sensor;
• Self-contained movement sensor;
• Digital odometric route indicator;
• Electrical mounting and mounting sets.

Onboard computer
Computer includes rugged computer with colored graphical LCD display with special software.

Inertial navigation measuring unit
Inertial navigation measuring unit is based on high-precision accelerometers and fiber-optical gyro- scopes. Strapdown inertial navigation system includes computer, fiber-optic gyroscopes, high-precision accelerometers.

Signal control and processing unit
Signal control and processing unit is intended to process signals received from strapdown inertial navigation system, satellite navigational unit, digital route indicator, generate signals and transfer them to the onboard computer.

Satellite navigation unit
Satellite navigational unit with digital atmospheric pressure sensor is intended to receive GPS/GLONASS signals. It switches on protected antenna and small-sized measuring receiver.

Self–contained movement sensor
Self-contained movement sensor is odometric system intended to calculate speed pulses of the vehicle (calculations of the whole system parameters in case signals from satellite navigation system are either non-available or untrue).

Digital odometric distance meter
Digital distance meter is intended to operate as part of inertial navigation system. The distance meter is used to measure the travelled distance as well as to deter-mine transport vehicle speed.
