5、d Test Procedure for Single-Degree-of-FreedomRate-Integrating Gyros.)This standard was prepared by the Gyro and Accelerometer Panel of the Aerospace Electronics Systems Society of theInstitute of Electrical and Electronics Engineers. It consists of two parts.Part I is a specification format guide fo

6、r the preparation of a rate-integrating gyro specification. It provides a commonmeeting ground of terminology and practice for manufacturers and users. The user is cautioned not to overspecify;only those parameters that are required to guarantee proper instrument performance in the specific applicat

7、ion shouldbe controlled. In general, the specification should contain only those requirements that can be verified by test orinspection. Parameters in addition to those given in this standard are not precluded. Figs 1 and 2 are to be used as aguide for the preparation of specific figures or drawings

8、.Part II is a compilation of recommended procedures for testing a rate-integrating gyro. These procedures, includingtest conditions to be considered, are derived from those currently in use. For a specific application, the test procedureshould reflect the requirements of the specifications; therefor

9、e, not all tests outlined in this document need be included,nor are additional tests precluded. In some cases, alternative methods for measuring performance characteristics havebeen included or indicated.The intent is for the specification writer to extract the applicable test conditions and equipme

10、nt requirements fromSection 9. for inclusion in the appropriate sections listed under Section 4.5. Similarly, it is intended that the writerextract the applicable test procedures from Section 10. for inclusion in the appropriate sections listed under Section4.6. Part II can also be used as a guide i

11、n the preparation of a separate rate-integrating gyro test specification withappropriate section numbering.Blank spaces in the text of this document permit the insertion of specific parameter values and their tolerances.Brackets are used to enclose alternative choices of dimensional units, signs, ax

12、es, etc. Boxed statements are includedfor information only and are not part of the specification or test procedures. The symbols used conform to IEEE Std260-1967 , Letter Symbols for Units Used in Electrical Science and Electrical Engineering. Terminology usedconforms to Aerospace Industries Associa

13、tion EETC Report 5 (Revision A), Standard Gyro Terminology.This document defines the requirements and test procedures for a conventional single-degree-of-freedom rate-integrating gyro in terms of characteristics unique to the gyro. The requirements contained herein are intended to coverapplications

14、in which the dynamic angular inputs to which the gyro is subjected are benign relative to the accuracyrequired. This will cover most gimballed platform applications and those nongimballed applications (for example,space vehicle attitude control systems) in which the dynamic inputs are not so severe

15、as to make additional parameterssignificant. The rate-integrating gyro provides a voltage output proportional to angular displacement of the case aboutthe input axis when in an open-loop mode or when captured by a servoed platform, or a current proportional to angularrate about the input axis when c

16、aptured through an external loop using the gyro torquer. A model equation is given inSection 6.3 for reference, to be included in a specification only to the extent necessary.Appendix A lists various rate-integrating gyro design features for which this format is applicable. The table is notintended

17、to make any suggestion regarding the selection of particular design features that might restrict the free choiceof manufacturers.ivThe IEEE will maintain this document current with the state of the technology. Comments are invited on this documentas are suggestions for additional material. These sho
