"Influence of Rotary Picture on the Accuracy of a PhotoalectrLc Angle Meter
in a Nongimbal Electrostatic Gyroscope"
Optiko Mekhanicheskaya Promyshlennest', No 12, 1972, pp 0-11.
Abstract: The use of the so-called "exotic" gyroscopes is pri.murily related
to the problem of coupling of the body of the gyro:wope to an iqolated
spherical rotor, which can be successfully solved using photoolvctric devices.
Among the many photoelectric devices for determination of infornarion on the
relative position of the axis of rotation of the spheTiCIAl rotor in a non-
gimbal gyroscope, pulse-width systems provide comparativo siripIkeity of de-
termination of the direction cosines cos >;, cos p atnd c(w-, v. This article
produces a general formula which can be us.erd to detertAiio the accuracy of
a photoelectric system. Various rotor pictures are &n:kI:),,,ed using this
formula. Kith otherwise equivalent conditions, the miniono- evror in calcula-
tion of the latitude angle is provided.whare cos A = t /'T, F(~~) -1/T, V~

Translation: Memory elements with 2-aperture transfluxor!j, inado of razterial
with a rectangular hysteresis loop, operating in the mode of parcial switch-
Ing, are well known. Tile basic shortcoming of those elemoats W the low
linearity of the accumulation characteristic U-f(N) N is the amplitude of
the pulse taken from the output winding of the transfluxor, 4 is the nurber
of pulses recorded), which occurs as a result of the non-Weal iractangularity
of the hysteresis loop of the magnetic material, the finite dimansions of
the transfluxor, and other factors. The metpory elements viggested differ
in that the output winding of the transfluxor Is connected to Its load
through a quadrupole which is made as an integrating RC cirmiturith
changing time constant. This allows linearization of the accuvialatioii
characteristic. 3 figs.
