Optical payloads use light to send, receive, and process information, and they’re much better than old-fashioned electronic systems for certain jobs. They work by using a […]

For a long time, satellites have used chemical rockets (burning fuel) to move around in space, including the important job of getting to the right orbit. […]

Satellites constantly circle Earth, collecting vital information used for everything from weather reports to scientific studies. These satellites need reliable ways to send this data back […]

Satellites in space can’t use GPS or landmarks to find their way. Instead, they use special tools to figure out which way they’re facing and where […]

Low Earth Orbit (LEO) satellites play a vital role in various applications, including Earth observation, communication, and navigation. Precise orbit determination (POD) is crucial for these […]

Space missions far from Earth are really tough on spacecraft, especially the on-board computer (OBC). Because they’re outside Earth’s protective magnetic field and often need to […]

Satellites need to know exactly which way they’re pointing for many important jobs, like taking pictures of Earth, communicating, doing science, and navigating. Sun sensors are […]

Knowing a satellite’s orientation (attitude) is essential for it to work properly. Magnetometers, which measure magnetic fields, are very important for figuring out a satellite’s attitude, […]

Feeding the world’s growing population is a huge challenge for agriculture, especially with climate change, limited resources, and changing consumer needs. Precision agriculture, which uses technology […]
