iNAV MODULE

The iNAV module is designed on the basis of a GPS/GPRS modem and allows collecting, processing, visualization and detailed analysis of the moving object data via GPS receiver and transmission through a GPRS channel allowing control and operational decision making. The collected data are stored in a database, which is stored and displayed as a computer map on the user monitor screen through an internet connection.

The module has a build-in MMC/SD card to store and transmit the navigation data to the database server. The iNAV module may be additionally equipped with a 3D inertial system to monitor the moving object. It is capable to receipt of the alarm state (thefts or accidents) and allows an advanced track analysis (speed, X,Y,Z - accelerations, track statistics, precarious driving style, etc.) to improve the route safety and security. The system is designed to establish real-time control of the special cargo or real-time protection against unauthorized object access.
