Appropriately, I am publishing today's episode from an airport - JFK. This is because it is about the positioning, navigation and timing vertical, specifically about how GPS can be spoofed and jammed, affecting air travel safety. Also appropriately, the recording with Dana Goward, President of Resilient Navigation and Timing Foundation, was occasionally of poor quality. The bandwidth gods have added a bit of ambience reflecting the jamming we talked about.

I found Resilient Navigation and Timing Foundation through a Wired article - "A GPS Blackout Would Shut Down the World". Yes, I'm at the podcasting stage where I read Wired articles and just reach out to the people/organisations profiled ;-) Wired used a provocative but truthful title which, perversely, we can be proud of. This is because a vertical in The Geospatial Index is Positioning, Navigation and Timing (PNT) companies. Companies, theory and technology in this vertical have, in Dana's words, produced a silent utility that the whole world has a critical dependence on. Well done to our industry, we are as vital as the water, power, sewer, telecom utilities! The PNT vertical is more well populated than others - 26 companies. There is a flyer in there recently, NextNav. I mentioned them during the episode with Dana and he gave some useful off the cuff commentary on the validity of their offering compared to other more economical solutions.

It was a fascinating episode. If you've ever wondered about those maps showing GNSS spoofing and jamming, Dana, a highly accomplished pilot, gave us a lengthy commentary on what they mean and spoke to some geographies where there is a strong risk of this silent utility failing to work properly.

A note about running the podcast. It is an experience of talking with some highly accomplished and capable guests. Reading Dana's profile, on gps.gov no less, gives one pause. I got lucky here - I did not read this profile before talking with him. I am glad, because I would have been a deer in the headlights. Some quotes:

"...he served as the maritime navigation authority for the United States with 12 different business lines budgeted at over $1.3B/yr, and represented the United States at the International Maritime Organization, International Assn. of Lighthouse Authorities, U.N. anti-piracy working group, and other international forums."

He has received a humanitarian award for a coastguard chopper rescue:

"...Helicopter Association International’s Igor Sikorsky Humanitarian Service Award for his rescue of two fisherman at the height of Hurricane Chantal..."

As such, Dana has intimate, professional pilot experience of the risks of GNSS spoofing and jamming. As leader of the maritime navigation authority of the world's largest economy, he has the same degree of knowledge from the perspective of an administrator. This means his call to action as a leader regarding resilience of this silent utility is worth listening to. His charity, Resilient Navigation and Timing Foundation, is also worth joining.

One has to wonder when the US will become tired of the embarrassment of being behind the Chinese. Even in the domain of navigation system resilience, the States is behind. I am grateful to Dana for identifying the problem as not being money or technology, but a lack of leadership. He has put himself in front of us as the leader on this issue. Let's listen and study what he has to say, we might find the required actions are straightforward to implement: https://rntfnd.org/.
