无论是在太空还是大气层中，了解并掌握导航球是成功飞行至关重要的前提。假如游戏视角不是 “尾追（Chase）” 模式，那么只有从导航球中才能判断目前的朝向，并判断飞行器该进行哪个方向的旋转。

导航球及所有的方向指示标志

速度

速度是飞行器相对参考点的速度大小。点击该区域会在地表速度和轨道速度之间切换，绿色数字显示其速度大小和类型。如果在地图上选定了目标点，还可以切换显示目标速度。

Ball instrument

The most important part is the center ball which shows the current orientation of the craft and multiple directions which maybe important for future movements.

While blue background indicates skyward directions the brown indicates groundwards. The white line in the middle is the artificial horizon.

Markers

On the navball are three different types of markers. All markers except the maneuver marker have an opposite marker on the other side of the virtual ball.

Level indicator

The level indicator shows the current orientation. As the navball is rotating beneath the level indicator, the navball is like a cockpit view without any window needed. So a rotation at the roll axis will turn the navball upside down.

Prograde and retrograde

The prograde and retrograde marker is facing in the direction of movement. As the craft orbits in most cases around a body these markers are moving. Burning at the prograde will accelerate the craft while burning retrograde will doing the opposite.

Target

If a target is selected the purple icons are indicating at which direction the target is. Because the target is also moving the target marker is also moving and isn't fixed.

Maneuver

If a maneuver is planned on the map, the maneuver marker is pointing in the needed direction to burn. This is the only marker without the opposite which could complicate using maneuver nodes when the engines are facing backwards.

Information around

On maneuvers, you additionally get a maneuver thrust indicator, a green bar and small info text right of the navball. The bar indicates the total amount of thrust required in the maneuver direction and it will deplete as you perform your burn. Below that is indicated how long your burn will have to continue until you complete your maneuver. This is a mere estimation based on your current thrust level, so altering thrust controls will also immediately alter this value. Below that is a timer indicating the time left until you reach your maneuver node where you should start your burn.

Throttle

Throttle is at how much power all engines are running (in percent). Beware of full throttle, as engines can overheat and then can be destroyed. This throttle will always control all engines, so if the engines are not balanced there is no way to balance this by reducing the power for those engines which apply to much thrust. Also it controls the engines equally at the given percentage so smaller engines will apply lower force.

Heading

The heading is the direction in degrees that the craft is facing. As most bodies are rotating eastwards it is more fuel efficent to head at the east.

G forces

G forces are the pressures exerted due to acceleration measured in a factor of g. One g is approximately 9.81 m/s².

Hide

Clicking the little arrow on the top of the navball (Hide) will toggles its display on-screen.

Basic controls

These are the most basic orientation controls of your craft, here is a short explanation on how their actions are represented on the navball.

Default control W moves the indicator down on the navball.

Default control S moves it up.

Default control A moves it left.

Default control D moves it right.

Default control Q rolls it counterclockwise.

Default control E rolls it clockwise.
