Iridium Communications is a company that helps people talk to each other using special devices that work anywhere in the world, even in places where there aren't any phone towers or internet.
Imagine you want to talk to your friend who lives on the other side of the world but there are no phone towers or Wi-Fi in that area. Well, Iridium has satellites up in space that can help you talk to your friend from anywhere in the world using a special device called a satellite phone.
These satellite phones look a bit different from regular phones because they have special antennas to communicate with the satellites in space. When you talk on a satellite phone, your voice is sent up to a satellite, and then down to the person you're talking to.
Iridium Communications also offers other kinds of services like tracking devices, messaging services, and internet connections for people who work or play in remote locations like boats, planes, or even in the middle of the desert.
So, in simple terms, Iridium Communications helps people talk and stay connected even in places where it would normally be impossible to do so.
