A gymballess, two axis rate gyroscope in which an inertia rotor is keyed on the electric motor shaft. The motor shaft comprises a flexible part (flexure shaft) adapted to flex upon precession of the inertia rotor in consequence of an angular velocity input around either of two axes normal ...
We are developing a MEMS-fabricated chip-scale atomic magnetometer that uses all-optical excitation to interrogate the spin-precession frequency of alkali atoms. Recently we demonstrated a magnetometer physics package that had sensitivit... P Schwindt,LA Liew,V Shah,... - American Physical Society ...
Detection of the earth's precession and nutation with a gyroscope Formulas are given for the angular velocities due to the earth's precession, nutation, wobble, and rotation rate variations. Of these motions, the 100 nano... ME Ash - Guidance and Control Conference 被引量: 0发表: 1977年 ...
this can be in some way "seen" intuitively in this way: if the plate is already horizontal, the precession and the speed of the disk are of course equal. If the disk is near vertical, the spinning of the disk (about its axis) is almost zero, because the upper point of the disk ...
Precession, along with other orbital factors, is also the reason for what is known as “length-of-day variation”. Essentially, this is a phenomna where the dates of Earth’s perihelion and aphelion (which currently take place on Jan. 3rd and July 4th, respectively) change over time. Both...
