Nowadays, modern communication means are nearly permanently available. However, in exceptional circumstances (e.g. disaster scenarios), this is not necessarily true. A successful operation of rescue forces depends substantially on sufficient communication capabilities via satellite. Fast movable antennas on vehicles may offer a good option. In the paper, a solution for satellite tracking of antennas on vehicles for mobile satellite communication is introduced. Two different systems are considered, which are selectively suitable for different driving modes (vehicle's standstill, driving along a road, driving off-road). Three modes of operation (initialization, open loop, closed loop) and appropriate controller structures are introduced. The controllers' concrete layout depends on the input quantities (measurement, estimation) available at the relevant mode of operation. Selected simulation results are given.
