„Elektroninvest LTD was founded in the end of 1994, and since than it has been working exclusively in the sphere of electronics.By the time of our existance it has been the improving and now proved distributor of measurement devices and electronic components in Bulgaria.Since 2005. company separate a development center and started his own design and manufacture of GPS systems for car parks. Until the beginning of 2009 we have introduced and employed over 3000 active tracking devices.

The proposed system for monitoring and controlling the movement of vehicles "Sleda" is designed and tailored to specific requirements and conditions in Bulgaria.
1. General effect of the implementation of GPS systems ELEKTRONINVEST:
- Sharp improvement in fleet management of each company.
- Fuel economy - to 30 - 40%. - Experience has shown that after the implementation of GPS system cost falls sharply, especially of large trucks with tanks over 200L. In some cases savings have been found between 100 and 400 liters per month compared to the periods to implement the system.
- Compacting and save hours of work.
- Effective control of the set of transport tasks.
- Significantly increase labor discipline.
- Generate a lot more information needed for other applications for the overall management of the company - electronic travel sheet and others.
2. Elements of the system:
The system consists of two main elements:
- Center for management and storage;
- Mobile ELT-3 in the vehicles.
Using GPS technology mobile specific data about the location and condition (rest or movement) of the vehicle to a point in time and through the GPRS connection through the GSM network to transmit real-time data to these centers for management. They are saved in a standard database and using specialized software are processed by different types of reports produced (for the distance traveled, time of stay, etc.) and displays the following left to the movement of vehicle graphics card in Sofia and Bulgaria. Software for visualizing and inquiries can be installed on a different computer than the center offices
