Referring to the generally known idea of tracking objects using a GNSS system, a concept for an aircraft and vehicle tracking system was developed, and individual system components were subsequently produced. The proposed system consists of three basic components: a positioning subsystem – onboard GNSS receivers, a data transmission subsystem, and a data visualization subsystem. The article contains a characterization of the individual system elements, with particular attention paid to the data transmission module using Digital Radio Mondiale (DRM), as well as preliminary research results.THE USE OF DRM TECHNIQUE FOR DATA TRANSMISSION IN OBJECT MONITORING SYSTEM
The idea of monitoring system for aircraft using satellite navigation systems is in line with the concept of the use of GNSS in aviation, both in Europe and worldwide. The proposed system consists of three basic components: the positioning, airborne GNSS receivers, the data transmission and the ground station. DRM (Digital Radio Mondiale) standard called digital radio is foreseen to be used for data transmission. This technique has got more benefits than FM or AM one. DRM has been successfully operated at power levels ranging from a few watts on 26 MHz through to several hundred kilowatts on long-wave.
The using DRM it can obtain a long range of data transmission at law power level. The paper presents the system architecture and preliminary results of studies on DRM technique. (…)
