FM Transmitter of APRS Telemetry in 144 MHz Band
Bohátka, Jan ; Šádek, Václav (referee) ; Urbanec, Tomáš (advisor)
APRS system is described are sent toin my essay, which is used for sending and receiving text messages. The text messages frequenc 144 MHz by using the modulation scheme AFSK. APRS communicate by using the protocol AX 25, which sends and receives the text messages in the area where are carried despatches and control bits as well. The whole area of high frequency part is in one integrated circuit. The control, coding and decoding of the area is the microcontroller’s job.

FM Transmitter of APRS Telemetry in 144MHz Band
Sabol, Martin ; Špaček, Jiří (referee) ; Urbanec, Tomáš (advisor)
This work deals with analysis of protocol APRS Automatic Positioning System for telemetry. There is analyzed the structure of the most important frames and their application. It discusses the processing of GPS data and subsequent modulation of the selected frequency. This work also describes and discusses the proposed peripheral devices and the used firmware.

The Design of Stratospheric Probe and Flight Simulator
Lindtner, David ; Kopečný, Lukáš (referee) ; Gábrlík, Petr (advisor)
This bachelor thesis deals with the design of the stratospheric probe as a device for measuring the parameters of higher layers of the atmosphere. The influence of different parameters on the resulting flight profile is shown in the simulations. On the base of real meteorological probes flights the model of atmosphere is verified and is used to estimate the landing point of our probe. The work emphasizes the design of key probe components such as communication devices, battery sources and sensors. At the end of the thesis, the data from the real flight of our probe are displayed and evaluated.
