A satellite stays in orbit by achieving a balance between its speed and the pull of gravity. The satellite must be traveling at a certain speed, known as orbital velocity, in order to maintain its orbit around the Earth. If the satellite's speed is too slow, it will fall back to Earth, and if it is too fast, it will fly off into space.
Satellites are powered by solar energy. They have solar panels that convert sunlight into electricity, which is then used to power the satellite's systems and instruments.
A satellite transmits data using radio waves. The satellite's antennas receive data from the ground, which is then amplified and transmitted back to Earth via radio waves. These radio waves can be received by ground stations or other satellites.
Satellites communicate with Earth using radio waves. They have special antennas that transmit and receive radio signals, allowing them to communicate with ground stations or other satellites in orbit.
A satellite maintains its position in orbit using small thrusters known as reaction wheels. These wheels can spin in different directions to adjust the satellite's orientation and keep it in its desired position. They are controlled by onboard computers that constantly monitor and make adjustments to the satellite's position.
