Djibouti has emerged as a critical connectivity hub at the crossroads of Africa, the Middle East and Asia. Its fiber-optic infrastructure is anchored by numerous submarine cables landing on its Red Sea coast – Djibouti hosts roughly 10–12 international undersea cables african.business techpoint.africa. These high-capacity links (e.g. SMW3, EIG, SEA-ME-WE-5/6, AAE-1, EASSy, WIOCC, Yemeni cable,…

HTS Technology Overview High-Throughput Satellites (HTS) are spaceborne relays designed to deliver dramatically higher data rates than traditional wide-beam satellites. They achieve this through numerous narrow spot-beams and advanced on-board processing, allowing aggressive frequency reuse. In practice, an HTS can deliver multiple times the throughput of a legacy FSS satellite using the same spectrum assets.publishing.service.gov.uk.…

Definition and Basic Principles Satellite imagery refers to images of Earth (or other planets) collected by orbiting satellites. These images are a form of remote sensing, meaning the data are acquired from a distance without direct contact. Satellites carry sensors that detect electromagnetic radiation reflected or emitted from the Earth’s surface. Most imaging satellites use passive sensors that rely…

Satellite Phone Basics What is a satellite phone? A satellite phone (or satphone) is a mobile phone that connects directly to orbiting satellites instead of terrestrial cell towers. This means it can place calls and send messages from almost anywhere on Earth, especially in regions without cellular coverage. Like a regular cell phone, a satphone supports voice calling…
