Available in PDF, EPUB and Kindle. Book excerpt: A seventy hour flight test program was accomplished to determine the suitability and accuracy of a low cost Omega navigation receiver in a general aviation aircraft. An analysis was made of signal availability in two widely separated geographic areas. Comparison was made of the results of these flights with previous work focused on VOR/ DME. Conclusions are drawn from the test experience that indicate developmental system improvement is necessary before a competent fail safe or fail soft area navigation system is offered to general aviation.

Book Synopsis General Aviation Omega Navigation in the National Airspace System by : Carl Edward Wischmeyer
Download or read book General Aviation Omega Navigation in the National Airspace System written by Carl Edward Wischmeyer and published by . This book was released on 1975 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Omega navigation has great potential as a navigation sensor for general aviation aircraft. Advantages of Omega navigation include signal availability at all altitudes, and no need for overflying of various stations. Also, because Omega coverage is not localized to small geographic areas, area navigation is an implicit capability of airborne Omega receivers. For use in the National Airspace System, several questions arise: How accurate is Omega navigation? How do you use the measurements made to give navigation information? What are the noise sources? How can these noise sources be eliminated or minimized? How do you use Omega in the National Airspace System? This thesis attempts to answer these questions based upon a 70-hour flight test program, mathematical models, analysis of the literature, and the author's experience as a commercially licensed, instrument-rated pilot. The thesis rather naturally divides into two parts: the first, Chapters II through VIII, attempts to answer the questions of Omega accuracy and operational characteristics. The second part of the thesis, Chapters IX through XVI, considers the questions of Omega implementation, including regulatory aspects and details required by good operating practice. The first part of the thesis, Chapters II through VIII, concerns Omega accuracies and the results of a 70-hour flight test program. Omega noise sources discussed in the literature were used for mathematical models, and a noise source not considered in the literature is discussed and measured. This is "short-term Omega noise", which is the noise in phase between successive measurements. For long time constant receivers, this noise is not important, but for light aircraft navigation, this is an important noise source. Analysis of the Weibull distribution showed little applicability of this distribution to Omega navigation errors, based upon the experience acquired in this program with a low-cost, commercially available Omega receiver. This flight test is also discussed in Refs. 16 and 17. In addition, four approaches were flown using Omega navigation, with surprisingly good results. Based upon the flight test data and the short-term noise measurements, mathematical models were made to determine RMS error of differential Omega with variations in update rate, and path-following accuracies available using Omega. The second part of the thesis concerns Omega implementation. The various configurations of Omega receivers are discussed. These configurations differ in what information is processed and how this information is used to give position information. Present regulations for Omega receivers are discussed, and future requirements for airborne Omega receivers, such as self-test and fail-soft capabilities, are discussed. Problems of waypoint setting errors with area navigation systems are discussed, and an easy method of error detection is shown which is compatible with Omega way point definition and which will allow use of standard aeronautical charts with minimal changes. Differential Omega is discussed in terms of message content and uplink medium. The results of the thesis are boiled down into the last chapter, the Conclusions. All of the meaty points are discussed briefly. Appendices include data on the approaches flown with the Omega receiver; the data collection and reduction for the flight evaluation program; and copyright agreement restrictions on reproduction of certain figures in the thesis based upon copyrighted approach plates.

Book excerpt: This study assessed the availability and applicability of error budget data for avionics certification requirements. The investigation includes a review of data for both station oriented (VOR/DME-RNAV) navigation systems and wide area (Loran-C, Omega and GPS) navigation systems. The primary thrust of the analysis was to determine the operational capabilities of the various navigation systems currently being certified. A secondary objective was to examine the viability of current certification procedures, techniques and accuracy criteria to any advanced navigation system. To accomplish these objectives, a detailed assessment of error budget data, error combination techniques and functional performance standards was performed.

This book was released on 1969 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of the study were to evaluate the accuracy of the Omega Navigation System operating in an airborne environment and the potential operational utility of the system for civil aviation. The error sources of Omega are identified, and their effect on the ability of an aircraft to maintain the desired flight track is evaluated. Characteristics of Omega which are pertinent to operation by civil aviation but which cannot be fully evaluated with available information are identified and recommendations for further investigations are given. The use of omega as a navigational aid with Omega signals continuously available at the input of the receiver, with compensation for lane loss, and with an appropriate phase-propagation model would allow air-craft operation at conventional aircraft speeds with rms cross-track deviations of 3 nmi if the 10.2 kHz carrier is used for position fixing. The most serious errors would result from failure of lane identification. Several methods of improving resolution reliability in airborne applications are given. Omega could be employed as a useful and valuable navigational aid if several potential problems can be resolved satisfactorily. While solutions to these problems can reasonably by expected with present technology, they have not been conclusively demonstrated. (Author).

Download or read book A Study of Signal to Noise Ratio, Lane Counting, and Position Accuracy Using the Omega Navigation System written by Glen Leif Francisco and published by . This book was released on 1976 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A forty-hour flight program was completed to study signal to noise ratio, lane counting and position accuracy using a low cost Omega navigation system in a general aviation aircraft. Specific test objectives were developed to investigate signals both on the bench and in the air. Signal to noise ratio and lane counting characteristics were investigated in a single frequency, uncorrected mode and in a pseudo-differential mode. It was learned that the received signal to noise ratio is highly correlated with lane counting characteristics and receiver navigability. The relationship between system accuracy and reliability was also examined. The Omega navigation system's bias and position accuracy were investigated with the aid of the Discrete Address Beacon System (DABS). A circular probable error of 3500 feet was observed. It was also determined that certain necessary hardware and system improvements must be implemented before a completely usable Omega navigation system can be offered to the general aviation user.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes a development and evaluation program for Differential Omega in general aviation. The program was a cooperative venture between the FAA and Transport Canada. SCT performed system design, program management, and flight test on behalf of the FAA. Tracor, Inc. provided modified Omega airborne receivers under subcontract to SCT. Flight tests took place in Alaska aboard a Convair 580 provided by the FAA. Monitor stations were located in Anchorage and at Deadhorse. The most definitive results were obtained from flight tests conducted in October 1980 and February 1981. Important results included: (a) data-link range varied from 44 nm to 198 nm, (b) random component of navigation error was 0.25 nm, 2-D RMS, (c) range decorrelation error was about 2 nm over a distance of 550 nm, (d) transient response of the system-following aircraft procedure turns was characterized by a positional overshoot of about 1.5 nm, followed by a monotonically decreasing error with a two-minute time constant. Recommendations are made for improving system performance. (Author).
