On–board navigation system “STRELA–1”

The system is intended for determining coordinates, defining the speed, heading and spatial orientation of combat vehicles (hereinafter “the CVs”), as well as for time synchronization of on-board equipment, displaying the data on the tablet screen and data outputting to the user and superior commander.

Besides, the system enables the navigation of the CV during marching, geolocation and positioning of the CV.

On-board Navigation System “Strela-1” has the functions as below:
• Defining CV navigational parameters – latitude, longitude, altitude;
• Defining current parameters of CV angular orientation – heading, roll, pitch;
• Defining CV movement parameters – travelled distance and speed;
• CV geolocation and positioning when GLONASS/GPS signals are jammed or missing;
• Synchronization of on-board equipment (generation of timing marks with reference to UTC (RUS);
• Indication of the CV position on the digital map;
• Defining and indicating of the marching parameters:
• distance to the starting position;
• heading to the starting position and deviation from the assigned heading;
• estimated time of driving;
• estimated fuel consumption.
• Recording the results of operation;
• Running automatic in-built serviceability test and outputting the results on displays.
