Satellite tracking system operates in online and offline modes. Online mode allows you to control the movement of transport in real time. When using the offline mode, the dispatcher receives information about the route done only at the time of inclusion of the device. This regime does not make it possible to adjust the situation along the way, but there is also a similar system cheaper than its online analogue.
