Satcom on the move (SOTM) is like having a TV in a car that can receive signals even while moving. Remember how you watch your favorite TV cartoon show at home on a big screen? The same show can be watched on a small screen in the car while traveling, and the picture won't get interrupted even if the car moves!
SOTM technology uses a satellite to send and receive data (just like how you use your parents' cell phone to call your friend). The satellite sends a signal to the terminal (like a TV antenna that captures signals) mounted on the vehicle, which sends the information to the TV (like how the antenna sends signals to the TV in your house).
Whether you're driving through a town, forest, desert, or even over a mountain, SOTM works in all kinds of environments. It's like having a magic TV that never loses signal, no matter how you move around. That's why it's very useful for things like military operations or emergencies when people need to communicate while moving.
Just like how your parents need to pay for the cell phone service, people also have to pay for the SOTM service, and it can be quite expensive. But it's worth it because it helps people stay connected even when they're on the move!
