Global real-time monitoring of means of transport and freight is necessary if we want to use the available resources in a sustainable way. Up-todate information about the fleet and cargo can also improve the efficiency and effectiveness of the logistics processes organization in supply chains. Such monitoring also enhances transport security. Generally accessible solutions for global tracking, however, are expensive and quite unreliable. The purpose of this article is to present the concept of the T-Traco system, which is used for global tracking of vehicles and cargo. Its main advantage, in comparison to the existing solutions, is the use of the USSD communication channel, which is more reliable and much cheaper than GPRS and SMS.
