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.
A radio signal traveling from Mars to Earth is one of the most impressive examples of how far modern communication technology has evolved. Somewhere millions of kilometers away, a spacecraft operating on another planet collects scientific measurements, captures images and studies an environment completely different from our own. That information…
Amazon Leo has reached a decisive point in its long and expensive attempt to challenge Starlink in the low Earth orbit broadband market. After another successful satellite launch, Amazon now says it has enough spacecraft in orbit to support continuous service across its first target latitudes. That does not mean…
NASA is preparing Artemis III as one of the most important missions in the modern return to the Moon. After Artemis II proved that astronauts could once again travel around the Moon aboard Orion, the next challenge is no longer simply reaching lunar distance. The next challenge is proving that…
Rural internet has always been a compromise. In cities, broadband competition usually means fiber, cable, 5G home internet, public Wi-Fi alternatives and several backup options. Outside dense population centers, the situation changes quickly. A house only a few miles from a town center may have no fiber, weak mobile coverage,…
Satellite communication is not defined only by the satellite in orbit. The frequency band used between the satellite and the Earth terminal is just as important. It affects speed, latency perception, link reliability, antenna size, terminal price, mobility, weather resistance, regulatory access and the type of service that can realistically…
For nearly half a century, Voyager 1 has been the quiet machine at the edge of human reach, continuing to send scientific data back to Earth long after its original mission had already become history. Launched in 1977, the spacecraft has traveled so far that even light now needs almost…
