9、6. All rights reserved. Introduction This standard is a minor revision of IEEE Std 647-1995 that corrects errors made in the publication process and adds minor technical improvements. It consists of two parts. Part I is a specification format guide for the preparation of a laser gyro specification.
10、It provides a common meeting 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 application should be controlled. In general, the specification sh
11、ould contain only those requirements that can be verified by test or inspection. Parameters in addition to those given in this standard are not precluded. Part II is a compilation of recommended procedures for testing a laser gyro. These procedures, including test conditions to be considered, are de
12、rived from those currently in use. For a specific application, the test procedure should reflect the requirements of the specification; therefore, not all tests outlined in this standard need be included, nor are additional tests precluded. In some cases, alternative methods for measuring performanc
13、e characteristics have been included or indicated. The intent is for the specification writer to extract the applicable test conditions and equipment requirements from Clause 11 for inclusion in the appropriate clauses listed under 6.5. Similarly, it is intended that the writer extract the applicabl
14、e test procedures from Clause 12 for inclusion in the appropriate subclauses listed under 6.6. Part II can also be used as a guide in the preparation of a separate laser gyro test specification with appropriate clause numbering. In general, the intent is for the specification writer to ensure consis
15、tency and traceability between Part II test procedures and Part I requirements for performance, mechanical, electrical, environmental, reliability, and quality assurance. To that end, a test procedure should not be listed in Part II unless a related requirement exists in Part I. Blank spaces in the
16、text of this document permit the specification writer to insert specific information such as parameter values and their tolerances, clause numbers, etc. Brackets are used to enclose alternative choices of dimensional units, signs, axes, etc. Boxed statements are included for information only and are
17、 not part of the specification or test procedures. The following standards were used in the development of this standard. ANSI/IEEE Std 260.1, IEEE Standard Letter Symbols for Units of Measurement (SI Units, Customary Inch-Pound Units, and Certain Other Units). ANSI/IEEE Std 268, American National S
18、tandard for Metric Practice. ANSI/IEEE Std 280, IEEE Standard Letter Symbols for Quantities Used in Electrical Science and Electrical Engineering. ANSI/IEEE Std 315, IEEE Graphic Symbols for Electrical and Electronics Diagrams. IEEE Std 528, IEEE Standard for Inertial Sensor Terminology. This standa
19、rd defines the requirements and test procedures for a single-axis laser gyro in terms unique to the laser gyro. The requirements contained herein cover applications where the laser gyro is used as an angular motion sensor in navigation and control systems. This introduction is not part of IEEE Std 6

21、r gyro is accepted to include the electronics necessary to operate the gyro and to condition the output signal. The laser gyro provides an output frequency proportional to inertial angular rate about its input axis. Annex A lists various laser gyro design features for which this format is applicable
22、. The list is not intended to make any suggestion regarding the selection of particular design features that might restrict the free choice of manufacturers. Annex B is an overview of dynamic and stochastic modeling. Annex C is an overview of noise process variance analysis as a method for determina
23、tion of the drift rate coefficients and the quantization coefficient. Annex D is a bibliography.
