Book excerpt: The United States Coast Guard (USCG) is in the process of upgrading the hardware of the Loran-C Radio Navigation System Control System. As part of this effort, the Computer-Assisted Loran-C Controller (CALOC) is also in need of improvement. CALOC performs four tasks: abnormality detection, time difference control, record keeping, and blink control. The work reported in this thesis focuses on time difference control. In many instances, does not accurately control the time difference error (within the established USCG control procedures. Two new algorithms are proposed here to control TDE more effectively: a Proportional Integral Derivative (PID) controller and a Kalman filter. Actual TDE data recorded at three different master stations covering five Loran-C chains is used to evaluate the performance of the proposed controllers. The PID controller shows a substantial improvement in control compared to CALOC, and the Kalman filter exhibits even better performance, based on preliminary results. This improvement in control correlates directly with an increase in both predictable accuracy and repeatable accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: What started with the sundial has, thus far, been refined to a level of precision based on atomic resonance: Time. Our obsession with time is evident in this continued scaling down to nanosecond resolution and beyond. But this obsession is not without warrant. Precision and time synchronization are critical in many applications, such as air traffic

Download or read book The U.S. Life-Saving Service written by Ralph C. Shanks and published by Costano Books. This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subtitled Heroes, Rescues and Architecture of the Early Coast Guard, this very complete record of the people, technology, architecture and exploits of the U.S. Life-Saving Service is a large-format book illustrated with 446 photographs and maps. It is especially strong on the wonderful and regionally varied architecture of the Service's stations, of which there were more than today's mariners or beachcombers can imagine -- 41 on the New Jersey coast, 31 on Lake Michigan, 13 on Cape Cod alone. In the last half of the nineteenth century, when coasting vessels numbered in the tens of thousands, the stations and their beach patrols were a necessity, and the surfmen managed dramatic rescues, many of which are recounted here.
