is a new vehicle tracking system combining GPS and GLONASS positioning systems with a higher level of reliability for complete telematics functionality. DISCO-B4-GLONASS is a free configurable smart tracking device which can be fully adapted to different user needs. Using a Quad-Band GSM/GPRS technology for two way worldwide communication, the ability to work with global navigation satellite systems (GNSS) - GPS and GLONASS, a high-capacity Li-Polymer rechargeable backup-battery, and housed in a weatherproof plastic case, the device is suitable for a wide range of mixed indoor/outdoor applications in the AVL, fleet management, asset tracking, vehicle security and recovery and transit sectors. The device has a protection class IP69K, which allows mounting of the device permanently on the roof of the vehicles, including buses, trucks, trains, vessels and other assets.

The device can operate fully autonomous and it is able to interact using sensors and actors. DISCO-B4-GLONASS can be adapted to existing tracking solutions and can be easily configured to gather or exchange relevant information with servers or users directly. An often used example is sending of the status reports or alarm messages directly to the users via SMS and/or to the tracking servers via TCP/UDP/HTTP/SMTP. Drivers logbook and data logging functionalities are combined in the history feature. Geofencing can be used to report violations of predefined routes or areas (for example, if a car enters or leaves a specific area or deviate a specific route). All of these features are perfectly integrated in a device concept which significantly reduces time-to-market and provides low cost tracking and security solutions.
