Node¶

class SpaceCenter.Node¶

Represents a maneuver node. Can be created using SpaceCenter.Control.add_node().

prograde: number¶

The magnitude of the maneuver nodes delta-v in the prograde direction, in meters per second.

Attribute:: Can be read or written
Return type:: number

normal: number¶

The magnitude of the maneuver nodes delta-v in the normal direction, in meters per second.

Attribute:: Can be read or written
Return type:: number

radial: number¶

The magnitude of the maneuver nodes delta-v in the radial direction, in meters per second.

Attribute:: Can be read or written
Return type:: number

delta_v: number¶

The delta-v of the maneuver node, in meters per second.

Attribute:: Can be read or written
Return type:: number

Note

Does not change when executing the maneuver node. See SpaceCenter.Node.remaining_delta_v.

remaining_delta_v: number¶

Gets the remaining delta-v of the maneuver node, in meters per second. Changes as the node is executed. This is equivalent to the delta-v reported in-game.

Attribute:: Read-only, cannot be set
Return type:: number

burn_vector([reference_frame = None])¶

Returns the burn vector for the maneuver node.

Parameters:: reference_frame (SpaceCenter.ReferenceFrame) – The reference frame that the returned vector is in. Defaults to SpaceCenter.Vessel.orbital_reference_frame.
Returns:: A vector whose direction is the direction of the maneuver node burn, and magnitude is the delta-v of the burn in meters per second.
Return type:: Tuple

Note

Does not change when executing the maneuver node. See SpaceCenter.Node.remaining_burn_vector().

remaining_burn_vector([reference_frame = None])¶

Returns the remaining burn vector for the maneuver node.

Parameters:: reference_frame (SpaceCenter.ReferenceFrame) – The reference frame that the returned vector is in. Defaults to SpaceCenter.Vessel.orbital_reference_frame.
Returns:: A vector whose direction is the direction of the maneuver node burn, and magnitude is the delta-v of the burn in meters per second.
Return type:: Tuple

Note

Changes as the maneuver node is executed. See SpaceCenter.Node.burn_vector().

ut: number¶

The universal time at which the maneuver will occur, in seconds.

Attribute:: Can be read or written
Return type:: number

time_to: number¶

The time until the maneuver node will be encountered, in seconds.

Attribute:: Read-only, cannot be set
Return type:: number

orbit: SpaceCenter.Orbit¶

The orbit that results from executing the maneuver node.

Attribute:: Read-only, cannot be set
Return type:: SpaceCenter.Orbit

remove()¶: Removes the maneuver node.

reference_frame: SpaceCenter.ReferenceFrame¶

The reference frame that is fixed relative to the maneuver node’s burn.

The origin is at the position of the maneuver node.
The y-axis points in the direction of the burn.
The x-axis and z-axis point in arbitrary but fixed directions.

Attribute:: Read-only, cannot be set
Return type:: SpaceCenter.ReferenceFrame

orbital_reference_frame: SpaceCenter.ReferenceFrame¶

The reference frame that is fixed relative to the maneuver node, and orientated with the orbital prograde/normal/radial directions of the original orbit at the maneuver node’s position.

The origin is at the position of the maneuver node.
The x-axis points in the orbital anti-radial direction of the original orbit, at the position of the maneuver node.
The y-axis points in the orbital prograde direction of the original orbit, at the position of the maneuver node.
The z-axis points in the orbital normal direction of the original orbit, at the position of the maneuver node.

Attribute:: Read-only, cannot be set
Return type:: SpaceCenter.ReferenceFrame

position(reference_frame)¶

The position vector of the maneuver node in the given reference frame.

Parameters:: reference_frame (SpaceCenter.ReferenceFrame) – The reference frame that the returned position vector is in.
Returns:: The position as a vector.
Return type:: Tuple

direction(reference_frame)¶

The direction of the maneuver nodes burn.

Parameters:: reference_frame (SpaceCenter.ReferenceFrame) – The reference frame that the returned direction is in.
Returns:: The direction as a unit vector.
Return type:: Tuple
