The single-axis analysis is then made applicable to the three-axis case by introducing a coupling factor. Of course, the shortcomings of this assumption, such as the omission of mechanical interactions, must be recognized. The inherently close association of the stability of the servo-system and the basis character of the input-output response will generally require that design requirements be compromised. The servosystem is essential to effect a suitable reduction in the influence of disturbances, and the factors involved in achieving stiffness must necessarily be considered. Finally, in discussing the design and features of the servoamplifiers it should be realized that the conditionally stable character of the system and the large attenuation involved in securing adequate phase lead create a difficult circuitry problem. In this regard, active research and development programs are under way toward the development of improved transistorized amplifiers.","PeriodicalId":332621,"journal":{"name":"IRE Transactions on Aeronautical and Navigational Electronics","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1958-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134537715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The output of the video processor was recorded in digital form and analyzed on a general purpose digital computer. The azimuths of approximately 30,000 simulated targets at signal-to-noise ratios of 3, 6, 10, and 15 db were estimated by several methods. A reliable indication was obtained of the detection efficiency, false alarm rate, and the obtainable azimuth accuracy under a variety of conditions. The data which have been processed so far indicate superior performance of the maximum likelihood method for azimuth estimation purposes.

Stellar Inertial Navigation 恒星惯性导航

{"title":"Stellar Inertial Navigation","authors":"R. Horsfall","doi":"10.1109/TANE3.1958.4201596","DOIUrl":"https://doi.org/10.1109/TANE3.1958.4201596","url":null,"abstract":"Automatic navigation of aircraft may be accomplished in a number of ways. Where radiative contact with the ground is satisfactory, systems such as the conventional radio ranges and the more recently developed hyperbolic grid techniques are economical and normally reliable. However, in some regions of the earth and under certain atmospheric conditions, these types of radio aids may not be reliable. Other systems that involve radiative contact with the ground include radio mapping techniques and Doppler navigation; these generally require more expensive airborne equipment, although they are less subject to atmospheric disturbances. But since in military applications radiation from an aircraft furnishes a potential means of enemy detection, such techniques are relatively undesirable. At the present time, Doppler systems are the least subject to this objection. Inertial navigation makes use of acceleration detection and integration for obtaining information on the progress of the aircraft over the surface of the earth. It is independent of radiative contacts, and therefore free from such detection. On the other hand, it is subject to errors resulting from instrumental imperfections. In particular, drift of the essential gyroscopes leads to cumulative errors in indicated position; consequently, pure inertial autonavigators are limited in the flight time over which their indications are satisfactorily accurate. Use of photoelectric telescopes (star trackers) in combination with an inertial system provides a tie to basic inertial space, such as to minimize or eliminate the cumulative effect of gyro drift. Such a combination is known as a stellar inertial autonavigator.","PeriodicalId":332621,"journal":{"name":"IRE Transactions on Aeronautical and Navigational Electronics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1958-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129425077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
