GPS Declassified Cited in Wilson Quarterly Article

A recent article, “Launching the Brick Moon: GPS’ Path from the Space Race to Smartphone,” by Aaron Lovell in the Wilson Quarterly, references GPS Declassified and quotes coauthors Richard Easton and Eric Frazier. Lovell summarizes GPS history, starting with the earliest concept for an artificial satellite conceived by Edward Everett Hale in 1870, and follows the story all the way to present issues raised the app economy, made possible by smartphones.

Wilson Quarterly is produced by the Communications Department of the Woodrow Wilson International Center for Scholars in Washington, DC.

Richard Returns to Milt Rosenberg Show

On June 30, 2015, Richard joined a panel discussion on the Milt Rosenberg Show to talk about the history and future of space exploration.

Other guests were Bill Melberg, a former aviation executive and now editor of AmericasUncommonsense.com, professional speaker and frequent writer on aerospace topics, and Dr. Paul Spudis, an astrogeologist and moon expert who is senior staff scientist at the Lunar and Planetary Institute in Houston, Texas.

GPS Update – The Space Show

On March 1, Richard Easton and Eric Frazier joined Dr. David Livingston, host of The Space Show, for a discussion about GPS modernization. Topics included new capabilities, schedule delays, cost overruns, international competition and potential threats to the system–a concern shared by many listeners, as evidenced by questions posed by email and callers. You can listen to the podcast here.

H-Net Reviews – Raymond O’Mara

“(The authors) tell an interesting story of how humans adapted an existing technology to provide benefits unseen by their original creators, a theme common in the history of technology….Ultimately, GPS Declassified achieves the authors’ goal of introducing the reader to important elements of the story of the development of GPS.”

Quest – Roger D. Launius

“… A solid basic history of the subject. As an introduction it is quite useful. It also seeks, in the authors’ minds, to correct what they view as errors and omissions in the GPS origins story. Finally, it tells quite a number of stories about the uses of GPS and how the technology has changed our lives, and then they go on to project possibilities for uses yet to be realized. This is a useful work about a complex topic.”

Phoenix Patriot Magazine Article Cites GPS Declassified

Keely Grasser, author of “From Duct Tape to Drones: Military Inventions That Impact our World,” in the Winter 2015 edition of Phoenix Patriot Magazine, interviewed Richard Easton and Eric Frazier for background information on GPS, one of eight innovations covered in the article. The key point she makes: GPS technology has spread throughout so many military, commercial and consumer industries that economists now find it impossible to accurately put a dollar figure on its overall worldwide impact.

GPS technology has grown so pervasive that its economic impact is immeasurable

Richard Easton Discusses GPS with Business Insider

Business Insider recently spoke with Richard Easton for input on its article, How Does GPS Work?

Richard noted that while GPS costs about $1 billion a year to maintain and replenish, it produces perhaps $100 billion per year in economic benefits, quite a “bang for our buck.”

Applications for GPS continue to expand, owing largely to a decision made at the beginning–to make the system passive. GPS satellites broadcast one-way signals, like a radio station, meaning an unlimited number of users can share them without transmitting anything back to the satellite, which would saturate the system and limit its use.

Spaceflight – Off the Shelf

“This book sets the record straight on just how remarkable has been the rise and rise of position-determination–the Global Positioning System, or GPS….(The) writers have combined their considerable talents to tell a highly readable story about the development of satellite navigation system….The book is a good primer and a stimulus to the more challenging aspects of what is now one of the fastest growing sectors in space applications.”

“From Harrison to GPS” – Richard Easton at The Explorers Club, NYC

Public Lecture Series feat. Richard Easton – May 5, 2014 from The Explorers Club on Vimeo.

From Harrison to GPS – This lecture traces the development of navigation from the 18th century longitude problem to the invention of the Global Positioning System. Easton will describe the two major proposed solutions to the longitude problem: accurate clocks as developed by John Harrison and observations of celestial objects such as lunars and the Jovian moons. He will then trace the history of satellite navigation proposals culminating in GPS which combines the two 18th century proposals, putting accurate synchronized clocks in satellites which are artificial celestial objects.
