High above Earth, in the crowded expanse of geosynchronous orbit (GEO) some 22,300 miles up, a set of American satellites quietly keeps watch. These are the Geosynchronous Space Situational Awareness Program (GSSAP) satellites – often dubbed “neighborhood watch” satellites – and they form a covert but crucial line of defense in space. Born in secrecy…

Introduction: LEO and the Rise of Small Satellites Low Earth Orbit (LEO) generally refers to orbits up to about 2,000 km above Earth’s surface nasa.gov. At these altitudes, satellites circle the globe in ~90–120 minutes, close enough for low-latency communications and high-resolution observations. In recent years, small satellites – typically massing from a few kilograms…

Introduction: Modern military forces rely heavily on satellites as force multipliers and intelligence assets in space. Over the last few decades, warfare has shifted toward highly technology-driven operations, making space-based capabilities central to strategic planning nsin.us. Military satellites – once limited to Cold War-era spy missions – now form the ever-watchful “eyes in the sky,” delivering critical communications, surveillance, navigation,…

Disasters – whether natural or man-made – often wreak havoc on local communication infrastructure. Hurricanes, earthquakes, and conflicts can topple cell towers, sever fiber-optic cables, and leave entire regions cut off. For instance, Hurricane Maria in 2017 damaged 95% of cell towers in Puerto Rico, leaving the island largely without phone service freepress.net. In such…

Low-Earth orbit (LEO) satellite internet has become a hotly contested “final frontier” of the telecom industry. Multiple players – notably SpaceX’s Starlink, the UK/India-backed OneWeb (now part of Eutelsat), Amazon’s Project Kuiper, and Canada’s Telesat Lightspeed – are racing to blanket the globe in affordable, high-speed internet from space. All seek to deliver broadband to…
