Abstract: This paper presents a project proposal aimed at developing a set of components in the form
of methods and tools supporting the process of detecting unauthorized satellite transmissions, realized
with the VSAT (Very Small Aperture Terminal). With its help it will be possible to draw radio
(spectral) maps of the existing satellite system, both for the design of new satellite system as well as for
identifying unauthorized changes to the radio spectrum showing the appearance of unauthorized
emissions. The results of the project may be interesting for governmental offices or security services,
that deal with detection of illegal emissions, as well as manufacturers and global integrators.

I. Introduction
Commonly observed development of information technology also applies to
satellite services sector, both in the two-way communication systems and broadcast
systems – mainly television and radio broadcasting. While the information
transmission systems develop very rapidly, whereas in the systems to safeguard
the proper use of satellite transmission resources no development is being practically
observed. Current status of satellite information technology security resembles
a situation of the early stages of the dynamic development of the Internet, when
all network systems operated on the principle of mutual trust. There were no actions
aimed at stealing confidential data, or taking control of servers and portals.
Over time the situation has radically changed, and today much attention is given
