The Satcom category covers satellite communication technologies, systems and real-world applications. Topics include geostationary, medium Earth orbit and low Earth orbit satellite networks, satellite internet, SATCOM terminals, antennas, uplink and downlink operation, frequency bands, latency, link budgets, ground stations, maritime and aviation communication, military satellite systems, emergency connectivity, anti-jamming techniques and the role of satellites in global telecommunications. The articles explain how satellite communication works in practice, what technical limitations it has and how modern satellite networks are changing broadband access, remote operations, defense communication and critical infrastructure connectivity.
Ham radio is not just a hobby – it’s a technical and communication challenge that enables amateurs to connect with people around the world. Thanks to advancements in technology, communication is no longer limited to Earth-based partners. It’s now possible to make contact with the International Space Station (ISS), which…
One of the most fascinating and essential tools in astronomical observation is the radio telescope. While optical telescopes observe the universe in visible light, radio telescopes detect radio waves in the electromagnetic spectrum. This allows us to study objects and phenomena that are otherwise invisible. In this article, we explain…
In recent years, increasing attention has been paid to satellites orbiting Earth—not only to their active operations, but also to their defunct yet still “wandering” presence. These objects are often referred to as “zombie satellites.” But what exactly does this term mean, and why do they pose a real threat…
The phenomenon of zombie satellites is not only fascinating from a technical or space research perspective, but also carries historical and political significance. The Cold War, especially under the Eastern European communist regimes, was full of surprising and heroic stories—among them, the little-known case of how the Polish Solidarity movement…
For decades, space exploration was the exclusive domain of government agencies. Launching spacecraft and satellites was strictly a state-managed enterprise. However, the past decade has brought profound change: an increasing number of private companies have entered the space sector, dramatically reducing the cost of satellite launches and accelerating innovation. This…
Satellite tracking has become an integral part of our lives today, even if we do not always realize it. We use it for navigation, vehicle monitoring, tracking our packages, and it also plays a key role in industry, agriculture, scientific research, and military applications. In this article, we will explore…
