Migration of telemetric narrowband radio networks to the IP standard
Stupka, Richard ; Lattenberg, Ivo (referee) ; Maršálek, Roman (advisor)
This bachelor’s thesis deals with the innovation of narrowband telemetry radio networks to the IP standard. This involves the modernization of old radio data networks that do not use the IP standard or are nearing the end of their life cycle. Renovation has a great benefit in terms of performance, reliability, and security. This modernization is achieved through migration, which means upgrading the old technologies to new ones. The objective of this thesis was to develop theoretical analysis and a technical procedure for network migration. It was deals with the currently used technologies and utilized components, parameters of individual network nodes, the actual design of the migration technical solution and network preparation. After the analysis and technical solution for migration had been performed, the proposed migration solution through simulated operation in a laboratory environment was verified. Based on the obtained information, configuration files for real-world usage were created, radio signal coverage in the field was verified and the communication capability in the newly built RipEx2 network was tested.

Seasonal variation of activity and pathogen prevalence in populations of the spiny-cheek crayfish
Matasová, Klára ; Petrusek, Adam (advisor) ; Slavík, Ondřej (referee)
The most widespread of invasive crayfish in the Czech Republic is the spiny-cheek crayfish (Orconectes limosus). It is a major disease carrier of crayfish plague, caused by the pathogen Aphanomyces astaci. The infection is lethal to European native species of crayfish. Transmission of this disease is usually associated with the spread of crayfish, which is dependent on their movement. The main aim of this work was to evaluate the differences in crayfish migratory activity in the Pšovka brook among seasons, and assess the factors that may affect it, by the use of radiotelemetry and trapping. We tested the hypothesis that crayfish use brook in the period from spring to autumn and then return back into a pond to overwinter. Furthermore, we evaluated how far from the pond crayfish migrate, and whether there is any relationship between migration and the season or water temperature. The results demonstrate that the activity varies among seasons (being strongly affected by breeding season) but in most studied periods did not significantly depend on water temperature. According to our monitoring, the spiny-cheek crayfish does not spread substantially to upstream parts of the Pšovka. Seasonal migration between the pond and the brook was monitored using two-way flow-through traps installed at the mouth of...

Telemetric monitoring of the feral pigeon ( Columba livia f. domestica) population at the Karlovo namesti square in Prague
Kanov, Štěpán ; Řezníček, Jan (advisor) ; Novák, Jindřich (referee)
"A Telemetric monitoring of the feral pigeon ( Columba livia f. domestica) population at the Karlovo náměstí square in Prague" This thesis deals with both the monitoring of numbers in the pigeon (Columba livia f. domestica, "the Pigeon") sites in question and also the spatial definition of the daily activities of individual specimens using a telemetric system. Previous researches gathered data on population density and food routes usually obtained by observation. Therefore we believe it's important to supplement this data with spatial movement maps of individuals that cannot be obtained by observation but the telemetry system allows us to do so in certain time period. The data obtained from GPS trackers will be processed into daily spatial activity maps of the specimen. These data will hopefully help us to gain insight into the life of not just specific individuals, but will also allow us to derive spatial activity of the entire population living in the locality in question. The results will be compared with the results from the previous pigeon count. This knowledge can be useful to population control, or serve in other studies. Keywords: pigeon, abundance, telemetry

Satellite Telemetry Archive
Vorálek, Jan ; Povalač, Aleš (referee) ; Urbanec, Tomáš (advisor)
This thesis deals with a design of telemetry archive of PSAT, PSAT-2 and BRICSat sattelites. This telemetry data need to be extracted from SDR IQ records. The thesis contains a Doppler effect theory and description of structure of telemetry data. Then it presents a design of a program for Doppler effect correction, demodulation and decoding of these records and saving the data to telemetry archive. Thesis also deals with analysis of decoded data.

Telemetry Data Collection and Evaluation
Spurný, Jan ; Krajsa, Ondřej (referee) ; Číka, Petr (advisor)
This thesis describes design and creation of application which collects and values telemetry data. Thesis consist of design and implementation which describes whole system, server settings as well as approach how to consume any given data. Corner stone of this application is based on given data from telemetry station (sensors) and projecting them on the map background. Application consist of user interface and logic how to project any given data into the map. Graphics interface is created using HTML, JavaScript and CSS programming languages. Logic itself is programmed by using backend language PHP including Laravel Framework in combination with MySQL database. Result of this thesis is working implementation covering administration user interface, working cooperation of MQTT server and APIs. There are also implemented all necessary parts for enablement of user interface with cooperation with map background layer. Implementation creates two possible ways how to install package necessary to run this app on Ubuntu system.

Spatial activity of birds and methods of its continuous monitoring
Havelka, Jan ; Sedláček, Ondřej (advisor) ; Kauzál, Ondřej (referee)
The aim of this work was to collect current knowledge of avian spatial aktivity focusing to its internal structure, using modern telemetry devices which allows continuous monitoring of small animal species. In the light of these new methods, avian home ranges seem to be more dynamic structures, changing during diurnal and nocturnal acitvities, breeding cycle, age, sex and social statut of a bird. Thanks to detailed radiotelemetry we can observe even secretive animal behaviour and its characteristics in three dimensions. Continual monitoring allows us to study migration in a detailed way, its influence to other parts of their annual cycle and to asses migration connectivity. In future these new information should be used for targeted conservation of endangered species.
