Page 3, 3.3.24, the text should be corrected to read as follows: _ _ (rad/h)/(rad/s)2, (/h)/(/s)2. Page 4, 3.6.4.1.1, text should be corrected to
6、read as follows: Sinusoidal: _ cm, in DA (double amplitude) _ to _ Hz; _ m/s2, g peak, _ to _ Hz. Sweep rate: _ minutes per octave (continuous). Exposure time: _ per axis. Page 4, 6.3, the subscript “s” in the model equation is smaller than the rest and should be corrected in each instance as follow
7、s: Page 9, 10.7.3.1.6.1, the text should be corrected to read as follows: Enclose the gyro in a temperature-controlled chamber. Stabilize the gyro at _C _C for_min, h. Repeat selected procedures of 10.7.3.1.1, 10.7.3.1.2. Record the gyro temperature in addition to the data listed in 10.7.3.1.1, 10.7
8、.3.1.2. Repeat the test at _C. This sensitivity can also be expressed in ppm/C.This sensitivity can also be expressed in ppm/mT or ppm/G. Gyro axes and characteristics of the field shall be defined. If exposure to a varying field is required, the nature of the variation shall be described. Demagneti
9、zation may be necessary following exposure. It should be noted that anisoinertia can vary due to decoupling of the spin-motor moment of inertia from the moment of inertia of the gimbal in the presence of angular acceleration about the spin axis. The decoupling will occur at angular accelerations whi

Record the inductance and resistance at frequency and voltage settings of _Hz and _ V. Page 16, 10.13.4.9, the fourth paragraph should be corrected to read as follows: For successful impedance matching with capture electronics, the second-order characteristics of the torquer may need to be considered.
