Episode Overview

This episode of Newt’s World delves into the remarkable story of GPS—the Global Positioning System—exploring its origins as a military innovation, its transformation into a ubiquitous tool for civilian life, and its enormous impact on the global economy and modern society. Newt Gingrich positions GPS as a powerful example of the synergy between government investment and private sector ingenuity, and highlights the visionary decision to make GPS freely available to the world.

Key Discussion Points & Insights

1. What is GPS and How Does It Work?

• GPS is a network of 31 satellites, 12,500 miles above Earth.
• Each satellite continuously transmits its location and the precise time via radio signals.
• A receiver calculates its own position by measuring the time differences from signals of four or more satellites—determining latitude, longitude, and altitude within a few meters.
• Atomic clocks onboard, synchronized to billionths of a second, are essential for accuracy.
• The system’s timing must account for Einstein’s general relativity: clocks in orbit operate at slightly different rates than those on the ground.
• Notably, GPS serves as a “daily practical demonstration of Einstein's physics.” (02:30)

“GPS... is a daily practical demonstration of Einstein's physics.”
— Newt Gingrich (03:00)

2. Genesis and Development as a Military Project

• Began as a project of the U.S. Department of Defense in the early 1970s.
• First GPS satellite: launched 1978; full constellation operational by 1994; total development cost: about $12 billion.
• Originally designed for precision navigation and weapons guidance.

3. A Presidential Decision Changes the World

• 1983: After the Soviet shoot-down of Korean Airlines Flight 007—a tragic accident tied to navigation error—President Ronald Reagan announced the U.S. would make GPS freely available to civilians once completed.
• This act, Newt notes, was not an engineering feat but a strategic and humanitarian move by a president:

“The decision that matters most in GPS history was made not by an engineer. It was made by a president.” (04:23)

• GPS would become accessible to everyone—no charge, no license, no restrictions.

---

4. Explosive Civilian Adoption and Technological Transformation

• Civilian adoption was first slow, then explosive.
• 2000: President Clinton removed military-imposed signal degradation, making civilian GPS as accurate as military.
• GPS chips rapidly decreased in size and cost:
  • Early 2000s: Standalone GPS devices sold in tens of millions.
  • By 2010: GPS chips in standard smartphones; navigation apps like Google Maps revolutionized daily life.

---

5. Hidden, Critical Applications Beyond Navigation

• Financial Markets: GPS timing is essential for synchronizing transactions and time-stamping trades with microsecond precision.

  “Without GPS timing, the modern financial system would not function.” (05:50)

• Telecommunications: Cell networks rely on GPS to sync towers.
• Aviation: Used for approach and landing.
• Agriculture: Modern farmers plant with centimeter precision thanks to GPS-guided equipment.
• Search and Rescue: Locating people in distress.
• National Institute of Standards and Technology estimate:

  “GPS contributes more than $1.5 trillion to the U.S. economy alone. Its global contribution is several times that.” (06:35)

---

6. Government Investment + Private Innovation = Success

• GPS illustrates the right relationship between government and the free market:
  • Only government could have made the upfront investment in the 1970s.
  • Only private entrepreneurship could invent transformative applications.

“GPS is a story about the right relationship between government and the market. Government invests in foundational infrastructure. The private sector builds on it.” (07:04)

• The importance of making foundational infrastructure openly available—a “gift” to humanity that has returned extraordinary value.

“One and a half trillion dollars in economic value — from a gift.” (07:15)

---

Memorable Quotes

• On the essence of GPS:

  “A deliberate, expensive, strategic gift from the American government to every person on Earth.” — Newt Gingrich (02:15)

• On the critical decision:

  “The United States had spent billions building a navigation system and was now giving it to the entire world.” (04:36)

• On the government-market partnership:

  “Government invests in foundational infrastructure. The private sector builds on it.” (07:04)

[Newt Gingrich]

Welcome to Newts World Podcast on the iHeart Podcast Network, episode 11 of the Greatest American Inventions. Today's invention is one most Americans use every single day without thinking about it for a second. And it was a gift. A deliberate, expensive, strategic gift from the American government to every person on Earth. GPS the Global Positioning System is a network of 31 satellites orbiting 12,500 miles above Earth. Each broadcast a continuous radio signal containing two pieces of information the satellite's precise location and the precise time. A GPS receiver picks up signals from multiple satellites simultaneously. By measuring the tiny difference in arrival times, it calculates its distance from each satellite. With signals from four or more, it pinpoints its location in three dimensions latitude, longitude, altitude to within a few meters. The timing has to be accurate to billionths of a second. The satellites carry atomic clocks, and GPS receivers must account for effects predicted by Einstein's general relativity. Clocks in orbit tick at a slightly different rate than clocks on the ground. GPS is, among other things, a daily practical demonstration of Einstein's physics. The system was developed by the department of defense beginning in the early 1970s. First satellite launched in 1978. Full constellation operational in 1994. Total development costs roughly $12 billion. Designed as a military system for precision navigation and weapons guidance. But the decision that matters most in GPS history Was made not by an engineer. It was made by a president. On September 1, 1983, Soviet fighters shot down Korean Airlines Flight 007, which had strayed off course. All 269 people aboard were killed, in part because of a navigation error. President Reagan announced that once GPS was complete, it would be made freely available to civilian users worldwide. No charge, no license, no restrictions. The United States had spent billions building a navigation system and was now giving it to the entire world. Civilian applications took off slowly, then explosively. In 2000, President Clinton ordered the military degradation of the civilian signal removed, making civilian GPS as accurate as military. GPS chips rapidly shrank and fell in price by the mid 2000s. Stand alone navigation devices sold by the tens of millions. By 2010, GPS chips were standard in smartphones, and navigation apps like Google maps transformed how people move through the world. But navigation is the most visible application, not the most important one. Financial markets use GPS timing to synchronize transactions. The time stamping of trades requires microsecond accuracy, and GPS provides it. Without GPS timing, the modern financial system would not function. Cell networks use GPS to synchronize their towers. Aviation uses it for approach and landing. Farmers use it to plant with centimeter precision search and rescue teams locate people in distress. The National Institute of Standards and Technology estimated GPS contributes more than $1.5 trillion to the U.S. economy alone. Its global contribution is several times that. Its global contribution is several times that. GPS tells us something important about the relationship between government investment and technological progress. GPS could not have been built by the private sector in 1973. The cost was too high, the timeline too long, the payoff too uncertain. Only government could make that investment big. Government alone couldn't have generated the applications, the navigation apps, the agricultural tools, the financial systems that made GPS survival. Those required entrepreneurship, competition, and the creative energy of the private market. GPS is a story about the right relationship between government and the market. Government invests in foundational infrastructure. The private sector builds on it. And if the government is wise enough, as Reagan's administration was, to make that infrastructure openly available. The results can be extraordinary. One and a half trillion dollars in economic value from a gift. Next time, we go back to the street. A sidewalk in midtown Manhattan where in April 1973, an engineer made a phone call that would eventually connect 8 billion people. The mobile phone.
