Abstract
The gyrocompass includes an improved indexing mechanism whereby the mechanical position of the gyroscope casing with respect to two orthogonal components of input rate may be measured.
Claims8
In a gyroscopic compass:
- rotatable internal casing means journaled about a normally vertical axis within external casing means,
- sensitive gyroscopic means supported within said rotatable internal casing means and having an axis normally coinciding with said normally vertical axis,
- motive means including non-reversing motor means within said external casing means for intermittently oscillating said rotatable internal casing means about said normally vertical axis,
- said motive means including flexible link means coupling said motor means to said rotatable internal casing means,
- mechanical stop means for precisely fixing the limits of said intermittent oscillations in cooperation with said flexible link means, and
- electrical contact means integral with said mechanical stop means whereby said motor means is driven for a predetermined time after each operation of said contact means whereby said flexure means is flexed to a predetermined degree.
