Zimbabwe connected to the internet relatively early, but access was very limited for many years. The first internet service providers (ISPs) emerged in the mid-1990s – Data Control & Systems was established in 1994 and MWEB in 1995 paynow.co.zw chatsports.com. At that time the internet was expensive and largely confined to corporations and elite users.…

The Satellite IoT (Internet of Things) revolution is kicking into high gear, promising to connect millions of devices in the most remote corners of the globe. By leveraging satellite networks for machine-to-machine (M2M) communication, this burgeoning sector is extending the internet’s reach far beyond terrestrial cell towers. Analysts forecast explosive growth in the coming years…

Executive Summary In summary, the 2025–2032 period will likely be remembered as the “gold rush” era for small satellite launch services, marked by fierce competition, rapidly advancing technology, and multiplying launch opportunities worldwide. For stakeholders – whether satellite operators planning constellations, investors evaluating launch companies, or government agencies seeking assured access to space – the…

Space weather refers to variations in the space environment between the Sun and Earth that can affect technological systems both in orbit and on the ground swpc.noaa.gov. It is generated by solar phenomena—particularly solar flares, coronal mass ejections (CMEs), high-speed solar wind streams, and solar energetic particle events—that release bursts of radiation and charged particles…

Imagine peering down at Earth through thick clouds or the dead of night and still seeing clear images of the surface. Traditional optical satellites are blind in such conditions – in fact, at any given moment about 75% of the planet is obscured either by cloud cover or darkness, making it inaccessible to optical imaging…

Satellites have become our planet’s orbiting guardians, silently circling Earth and gathering data that help scientists unravel the story of climate change. Using advanced sensors, these high-tech observers measure everything from global temperatures and greenhouse gas levels to shrinking ice sheets and disappearing forests. The result is a revolution in climate monitoring – a wealth…

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…

Imagine sending a text from the middle of the ocean or deep in the mountains with no cell tower in sight. That’s the promise of Starlink’s new Direct-to-Cell technology – a “cell tower in space” that lets ordinary phones connect via satellite when terrestrial coverage is absent. In recent trials, SpaceX’s Starlink satellites have successfully…
