The CENTENNIA Historical Atlas

About Frank Reed, Creator of Centennia :

• Head Cartographer, Centennia Historical Atlas
  The principal focus of my business, Clockwork Mapping, is the development and marketing of the Centennia Historical Atlas. The Centennia Atlas was, for over fifteen years, required course material for all students at the US Naval Academy at Annapolis, MD. Please visit HistoricalAtlas.com to learn more. My youtube channel has over 1.2 million views. Other videos, generally copyright-violating, based on my map animations have accumulated over twelve million hits.
• ReedNavigation.com
  I also teach all of the workshops in celestial navigation presently offered by ReedNavigation.com, including all online workshops. Although on-site classes are currently cancelled due to social distancing, I also teach all of the classes currently offered at Mystic Seaport Museum (MSM), as well as Boston Community Boating Inc. (CBI) and other venues. I am fluent in nearly every technique and tool in celestial navigation from ancient historical methods to the most modern computer-based applications, and I am the world's leading expert in the topic of lunars.
• StarTalk television: Celestial Navigation Expert
  I was recently a guest, aboard as an expert in celestial navigation, on the December 3, 2017 episode of StarTalk, a science talk-show hosted by Neil deGrasse Tyson which airs on the National Geographic Channel (look for S04E10). The episode is also available for streaming (paid) on youtube, itunes, etc. Dava Sobel, author of "Longitude" also joined us in the studio for one segment.
  

  

  

• Developer, GPS Anti Spoof apps for Android and iOS
  My "GPS Anti Spoof" app has been released for iOS and Android. The app does everything. Shoot the Sun (or Moon, planet, star) with your sextant and directly compare with the displayed altitude in the app. No calculations / no paperwork. It's great for sextant training --you get instant feedback. And it easily detects GPS spoofing, if you're worried about pirates and that sort of thing! Unlike nearly all other available apps and software, this app also incorporates the deflection of the vertical, which can throw off your sights by more than one minute of arc near many islands. The app is dead-on accurate. Details and download links: ReedNavigation.com/GPSantiSpoof/.
• Invited Whaleship Voyager
  Celestial navigation expert on the 38th Voyage of Mystic Seaport's 1841 whaleship Charles W. Morgan, July 2014. Demonstrated historical celestial navigation techniques at sea off the coast of Massachusetts. Organized and operated 38Talk, an online community for discussions among Voyagers and others related to the 38th Voyage. Featured guest in live webcast from the deck of the Charles W. Morgan as we sailed among the whales on Stellwagen Bank north of Cape Cod, July 2014. I discussed the basics of "nautical astronomy" for an introductory audience: watch the video. I also appeared briefly on the CBS Evening News in their coverage of the 38th Voyage.
• Gravitation and Physics
  I am an expert in gravitational physics including topics ranging from theoretical general relativity to practical tidal analysis. My thesis at Wesleyan University (Middletown, CT, 1984) was awarded High Honors, and I was also the winner of the Sherman Prize in Mathematics and the Bertman Prize in Physics. Read an article about me from Physics World magazine in their Once a Physicist column.
• Leap Second Conference
  In October 2011, I presented a paper on celestial navigation and the issue of "leap seconds" at the conference on "Decoupling Civil Timekeeping from Earth Rotation" hosted at the headquarters of AGI near Philadelphia. Neil deGrasse Tyson, television personality, host of the new Cosmos, and director of the Hayden Planetarium in New York City, also joined us as an interested guest. Here's a photo of us.
• StarTalk Radio
  In addition to appearing recently on StarTalk television, I was a guest on Neil deGrasse Tyson's StarTalkRadio in 2012: StarTalkRadio: Time Lords and the Science of Keeping Time (to listen to my contributions, go to time stamps 12:09-14:50 and 24:20-25:35).
• Published article "Celestial Navigation and UTC"
  On the significance of changes in 'leap second' procedures and its potential impact on traditional celestial navigation. Presented at conference in Exton, PA. October, 2011. Published in the Journal of the American Astronautical Society, 2012. Read the preprint.
• Interview on NPR's "Here and Now"
  Discussing the future of celestial navigation and the recent announcement that some basic instruction in celestial navigation will once again be part of the curriculum at the US Naval Academy. October 2015. Listen here.
• "After Longitude", National Maritime Museum
  In March 2012, I delivered two presentations on lunars at the "After Longitude" conference at the National Maritime Museum at Greenwich, UK (a few hundred yards from the Prime Meridian).
• Susan P. Howell Memorial Lecture
  In June 2004, I gave the Susan P. Howell Memorial Lecture on the topic of Lunars focusing on the use of lunars aboard the Boston trading vessel Reaper in 1809-1810. The logbook of this voyage is in the research collection at Mystic Seaport.
• Navigation Conferences
  I have organized "Navigation Weekend" conferences in 2006, 2008, 2010 and 2017 bringing together navigation enthusiasts, scholars in the history of astronomy, and practical navigators to the Treworgy Planetarium at Mystic Seaport. I also did numerous presentations of my own at these conferences on lunars, the history of the Nautical Almanac, and other topics.
• Experience at Mystic Seaport
  Though I am not on staff now, I've been employed by Mystic Seaport directly several times over the past couple of decades. I have presented over 3000 planetarium lectures there primarily focused on topics in celestial navigation.
• Management of NavList
  I manage NavList, a community devoted to the history, modern practice, and future of celestial navigation and other forms of traditional position-finding. NavList began as an online community and our message boards continue as, by far, the most active arena for online discussions on these topics.
• Navigation Instructor, Physics Instructor: Northeast Maritime
  I've recently taught several intensive two-week USCG licensing classes in celestial navigation at Northeast Maritime Institute in Fairhaven, Massachusetts. I am a USCG-approved instructor in celestial navigation. I also taught an introductory college level conceptual physics course at NMI during the Winter/Spring term of 2017.
• Editor, Pub.249 "Tables for Navigation"
  I maintain the celestial navigation tables known as "publication 249", marketed commercially by Celestaire, Inc., which are used by thousands of vessels at sea as a backup method of celestial navigation.
• Invited Planetarium Lecturer, Wickware Planetarium
  During the fall of 2016, I presented two special hour-long planetarium programs at the Wickware Planetarium, Eastern Connecticut State University in Windham, Connecticut focused on topics in celestial navigation.
