This article describes the design of a global monitoring system for remotely piloted aircrafts using a satellite, radio, and GSM datalink. The final solution aims for small, general-purpose drones weighing less than 20 kg, which could be engaged into an Internet-of-Things concept. In this work we propose a solution for drone operation and crash monitoring, protection of flight-restricted areas, protection of urgent low-altitude flights (emergency), and a flight hours logging system for general purpose drones or remotely piloted airplanes. The article describes the certification process of current aerospace products to attempt to apply this certification process for RPAS. We define the categories of vehicles and specify for which ones our system is designed. Next we describe the data measurement and acquisition unit which measures flight data and transmits them to a ground database in real time. We compare the available technologies and provide reasoning for the selected solution where we specify the disadvantages of the selected technology and how we overcome those. The article provides description of material and data flow, which is related to our business model and what services we can provide to customers. Finally, the results of the system's initial testing are provided.
