Abstract:

A survey of the low rate sensing capabilities of in-production and developmental mechanical instruments is described. Mechanical rate instruments include primarily the single degree-offreedom gyro, spring restrained and unheated, and electrically restrained, heated and unheated. Also discussed are two classes of vibratory gyros and the use of angular accelerometers. TwoAPPENDICES ANALYZE THE EFFECT OF RATE SENSOR DEAD-BAND ON GAS CONSUMPTION, AND THE USE OF A LOW RATE SENSOR TO DETECT SATELLITE YAW MOTION. It is concluded that 1 The electrically restrained, heated gyro has the best over-all low rate sensing capabilities 2 The spring restrained gyro has over-all performance qualities which should be adequate for many missions 3 Integrating the output of an angular accelerometer appears to be a very promising prospect and 4 Vibratory gyros are in the early stages of development and little is known about their actual performance.
