The possibilities of using the methods and tools in other projects Developed in the TransSat project automatic image analysis algorithms in both the visible and infrared light can be used in other areas, such as mine protection of routes, where move patrols and convoys during a realization of peace missions abroad. The images obtained from the daily “test flight” route by an unmanned aircraft will be taken automatically, based on the algorithm developed in the TransSat project, compared with the reference image of the area recorded in the database. In case of discovering of disturbing differences, in the suspected place will be sent an engineer patrol to conduct a detailed reconnaissance. Another purpose of the project will be to develop numerical models of the socalled radiated emissions interference, emitted by the complete VSAT systems. Currently, manufacturers of VSAT systems provide information about the directional characteristics of the mirror of the VSAT antenna. Rarely there are information about radiation characteristics of the complete antenna with tie parts to hold the radiator, and the exceptions may include directional characteristics of complete VSAT systems, taking into account the impact of installation of all elements of the signal path, on the radiated interference emissions by the VSAT system. The lack of such information generates problems with the so-called co-located compatibility, appearing in the case of having to install several VSAT systems in close proximity to each other, such as satellite centers (called teleport, hub), or the work of several informational agencies in the given location. Developed in the TransSat project radiated noise emission models in VSAT systems, will allow to analyze in advance the possibility of appearing interference of several co-located VSAT terminals. TransSat will be applied with methods and tools supporting the process of detecting unauthorized satellite transmissions, and thus the radio emission in the frequency range 7-38 GHz can be successfully used in the preparation or updating of maps of the radio and radiolines installations. Screenshot of part of such a map was shown in Figure 4. Figure 4. Example of radiolines map
Chapter 4: Information Assurance & Cyber Defence 437 VI. Summary Currently it is not possible to effectively detect unauthorized emissions of satellite signals, and the more its overhearing or recording. There are measurement stations in the market, but they operate in a very limited bandwidth. For example, Mobile Measuring Station made by KenBIT company operates in 20 MHz–3 GHz, while the signals are transmitted by satellite also at higher frequencies, such as DVB-S takes the band from 10.7 GHz to 14.5 GHz, or Teledesit that works at about 29 GHz. The result of this project will be a unique solution to examine the full range of satellite frequencies – from a few hundred MHz to 32 GHz. Owing to this it will be possible to draw radio (spectral) maps of existing satellite system, both for the design of new satellite system as well as for identifying unauthorized changes to the radio spectrum, indicating the appearance of unauthorized emissions. For the purpose of the project it is expected to call TransSat consortium, that will be composed of research units (Military Communication Institute and the Institute of Aeronautics and Applied Mechanics of Warsaw University of Technology), and the companies involved in the subject of converging with the problems of the project, namely: Astri Polska (APL) and WOOD System Integrator (WOOD). In the results of the project may be interested: Office of Electronic Communications, which deals with the detection and analysis of radio signals and the detection of illegal emissions, the state security services such as The Internal Security Agency and the Military Counterintelligence Services, as well as manufacturers and global integrators such solutions for the detection and interception of unauthorized satellite emissions.
