There are two viewing modes. By default Easy View Mode is enabled. This causes the satellites to be rendered fully illuminated at all times. They also are a constant size. With Easy View Mode disabled, the satellites are rendered with the correct lighting based on their position relative to the sun. This means that they will be dark when they are in the earth's shadow. The size of the satellites also defaults to 1x which is not able to be seen because they are so small. You can adjust the scale of the satellites in either mode using the slider in the top left.

You can use the left mouse button or touch and drag to rotate the camera. Use the mouse wheel or pinch to zoom in and out. You can also use the right mouse button or two finger touch to pan the camera.

In the normal view mode, satellites near the mouse are linearly scaled by distance from the mouse. This is to help see the satellites better. Otherwise it would be nearly impossible to locate them. In both view modes, you can hover over a satellite to see its name and altitude. This feature is disabled on mobile.
