Gimbal lock is the loss of one degree of freedom in a multi-dimensional mechanism at certain alignments of the axes. In a three-dimensional three-gimbal mechanism, gimbal lock occurs when the axes of two of the gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space. The term ...
A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow ...
One must be aware of singularities in the Euler angle parametrization when the pitch approaches ±90° (north/south pole). These cases must be handled specially. The common name for this situation is gimbal lock. Code to handle the singularities is derived on this site: www.euclideanspace.com
Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...
What can gimbal lock is an instrument or device mounted in the airplane, but in this case the mounts for the gimbal should be fixed relative to the airplane's vertical axis, not the Earth's vertical axis as shown in the figure.

Flu activity remains "elevated" in the United States but is starting to show signs of abating, according to new federal data published Friday. The 2024-25 flu season was classified by the Centers ...
When the transient torque ends, the control program will stop the gimbal movement, and the rotors will be left pointing more forward than before. The inflow of unwanted forward angular momentum has been routed through the CMGs and dumped into the rotors; the forward component of their total angular momentum vector is now greater than before.
Gabbard has in the past called Snowden a “brave” whistleblower who uncovered damning civil liberties violations by the intelligence community.
