Advancements in satellite technology have made it possible to provide global internet coverage, track natural disasters, and improve surveillance. Low Earth Orbit (LEO) satellites have been developed to enable faster data transmission with lower latency for high-speed internet connectivity, while CubeSats are miniaturised satellites with a volume of 10 cm cubed and used for scientific research, Earth observation and communication. Inter-Satellite Laser Communications (ISLC) use laser beams to transmit data between satellites, achieving faster data rates, higher bandwidth, and better reliability. These advancements have significant potential, from extending the life of satellites to providing positive impacts on a range of sectors.

Sky’s the Limit: New Innovations in Satellite Technology

Satellites have been an integral part of modern communication systems, weather forecasting, navigation, and defense for several decades now. However, recent advancements in satellite technology have paved the way for new possibilities, including global internet coverage, tracking natural disasters, and surveillance. In this article, we will explore some of the latest developments in satellite technology and its impact on various sectors.

Low Earth Orbit Satellites (LEO)

Traditional geostationary satellites operate at an altitude of 36,000 km and cover a large area of the earth’s surface. However, they suffer from slow latency and limited bandwidth, making them unsuitable for providing high-speed internet connectivity to remote areas. Low Earth Orbit (LEO) satellites, on the other hand, fly at an altitude of 160-2000 km, enabling faster data transmission with lower latency.

In recent years, several companies, including SpaceX, OneWeb, and Amazon, have launched or planned to launch thousands of LEO satellites to provide high-speed internet connectivity worldwide. SpaceX’s Starlink constellation, for instance, has launched around 1,800 satellites and aims to provide internet access to underserved areas and remote locations.

CubeSats

CubeSats are miniaturized satellites with a volume of 10 cm cubed and weigh around 1 kilogram. They are used for scientific research, earth observation, and communication, among other applications. CubeSats are significantly cheaper and easier to manufacture than traditional satellites, making them ideal for educational institutions and small businesses.

Several CubeSats are currently in orbit, with some of them being used for experimental purposes, including testing new propulsion systems and solar panel designs. However, their small size limits their capabilities, and they can only carry a limited amount of payloads.

Inter-Satellite Laser Communications

Traditional communication between satellites is achieved using microwave signals, which suffer from interference and signal degradation. Inter-Satellite Laser Communications (ISLC), on the other hand, use laser beams to transmit data between satellites, resulting in faster data rates, higher bandwidth, and better reliability.

ISLC has several potential applications, including satellite-to-satellite communication, earth observation, and improving navigation systems. It can also extend the life of satellites by reducing the need for fuel-intensive orbit correction.
