The paper presents an initial concept of a flying object trajectory recording system employing a data recording algorithm (operating on the base of the raw recorded data) and radio transmittion modules. Operation of developed system is based on microcontroller Atmega, a magnetometer module, a gyroscope and acceleration meter, and a RF miniature transmitter and SDR receiver. The initial performance of application analysing and recording the data is provided. Moreover, subunits available on the market have been reviewed to select the modules dedicated to the system. A possibility for record-ing the transmitted navigation data was studied. Application of SDR receiver in combination with a computer application monitoring the data transmission channel up to 1 kilometre is described with the configuration of the system, and the schematic of measurement transmitting and receiving modules, and the surveillance of transmitted data quality. The basic algorithm of application using the received data for reconstruction of object’s flying path and prediction of a fall point is presented. Moreover an analysis is included for possible applications of the above mentioned system.
