- n. A small, movable auxiliary graduated scale attached parallel to a main graduated scale, calibrated to indicate fractional parts of the subdivisions of the larger scale, and used on certain precision instruments to increase accuracy in measurement. Also called vernier scale.
- n. An auxiliary device designed to facilitate fine adjustments or measurements on precision instruments.
- adj. Of, relating to, or having a vernier.

- n. A secondary scale with finer graduations than the primary scale of a measuring device; the vernier measures between graduations of the larger scale.
- n. A secondary control input with finer control than the primary, or coarse, input; for example the vernier frequency tuning knob on a radio.

- n. A short scale made to slide along the divisions of a graduated instrument, as the limb of a sextant, or the scale of a barometer, for indicating parts of divisions. It is so graduated that a certain convenient number of its divisions are just equal to a certain number, either one less or one more, of the divisions of the instrument, so that parts of a division are determined by observing what line on the vernier coincides with a line on the instrument.
from The Century Dictionary and Cyclopedia
- n. A small movable scale, running parallel with the fixed scale of a sextant. theodolite, barometer, or other graduated instrument, and used for measuring a fractional part of one of the equal divisions on the graduated fixed scale or arc.

The name vernier, now commonly applied to a small movable scale attached to a sextant, barometer, or other graduated instrument, was given by Lalande who showed that the previous name nonius, after Peter Nunez, belonged more properly to a different contrivance.
It will be seen that the scale proper is attached to the quartz wedge, which is moved by the milled head, and attached to the other quartz wedge is a small scale called a vernier which is fixed, and which serves for the exact determination of the movable scale with reference to it.

So how about building this from either a shuttle orbital maneuvering engine or if this is too powerful, a cluster of shuttle RCS thrusters, either the primary or vernier as required.
With their passing went also the last sensation of weight, except for occasional ghostly pats and nudges as the low-powered vernier jets made infinitesimal adjustments to the orbit.
