The late, great, oft-quoted Yogi Berra, in an interview shortly before his passing, was quoted as saying “I never said most of the things I said.” For our purposes, let’s concentrate on one of his most famous quotes: “When you come to a fork in the road, take it.”
On to GPS. I use the term GPS in a ubiquitous PNT (position, navigation and timing) sense for simplicity, because most people today use the term in a universal sense, similar to how we say “Google It” no matter which search engine we’re actually using.
Today, GPS is indeed at a crossroads, and there are multiple paths or avenues to follow — or Courses of Action (COA), as the government likes to say.

Let’s review the various GPS programs and see how they’re faring.
GPS III
Let’s be conventional and start with the hardware, the actual satellite bus (vehicle) being built by Lockheed Martin Space Systems in its Waterton facility in the beautiful foothills of the Rocky Mountains in Littleton just west of Denver, Colorado.
In an October 2015 speech before the International Astronautical Congress in Jerusalem, Israel, LMCO Chairman, President and CEO Marillyn Hewson stated the following in a marvelous speech entitled “There are No Borders in Space: International Cooperation Will Drive the New Space Age:”
“We must focus on three priorities for the future of space. The first is space as an instrument to create global industrial partnership. Second is space as a driver of economic growth. And third is space as an opportunity to inspire the next generation of innovators.”
Chairman Hewson concentrated on the future of space, as are we, and probably due to her venue, she naturally chose to focus on international cooperation. She went on to say this about GPS specifically:
“GPS III, the next-generation of the U.S. Air Force’s Global Positioning System, will share a new, common civil signal with other international navigation satellites like Galileo and GLONASS. That means people around the world will have more accurate and reliable positioning data and connectivity from a truly global positioning constellation.”
