Chad, a vast landlocked nation in Central Africa, has one of the world’s lowest rates of internet connectivity. As of early 2025, only about 13% of Chadians use the internet, compared to a global average around 60% capmad.com. This places Chad near the bottom globally in internet access. The digital infrastructure is underdeveloped, and most…

Global Navigation Satellite Systems (GNSS) like GPS have revolutionized how we find our position on Earth. Yet, the standard GPS accuracy (on the order of several meters) often isn’t sufficient for missions like precision farming, engineering surveys, autonomous navigation, or tectonic measurements gssc.esa.int. To bridge this accuracy gap, two advanced techniques have emerged over the…

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…

Definition and How Geostationary Orbit Works A geostationary orbit (GEO) is a circular orbit around Earth’s equator at approximately 35,786 km altitude (about 22,236 miles) where a satellite orbits once per sidereal day (~23 hours 56 minutes) in the same direction as Earth’s rotation en.wikipedia.org esa.int. This precise altitude and orbital period make the satellite…
