In this episode of Space Minds, Mike Gruss talks with Iridium’s Tim Last. They discuss competition in the direct-to-device and Internet-of-Things sector as well as solutions to GPS jamming problems that have flared up in recent months. This conversation was recorded before today's announcement that Rocket Lab plans to acquire Iridium.


Finding solutions to jamming and spoofing

FROM THE CONVERSATION


Mike Gruss: There are always reports of GPS jamming. ... That's been a persistent problem for a long time, and it seems to be an increasing problem. You guys are looking at a ship-based solution to secure [position navigation and timing]. Tell me about how that could scale and some of the barriers to adoption.


Tim Last: We already have launched today a resilient PNT service ... At the heart of our service is the delivery of a time signal, globally. From that, you can infer and determine a location. Think of it as GPS but not on GPS spectrum or power. The qualities of Iridium's network and signal is being in low Earth orbit. That means it's much lower to the Earth and much higher power. That means it can provide resiliency qualities. With enough power and energy, you can jam any wireless signal. But we're finding that there are many use cases around the world, not only in the military space but also in commercial environments, where a more secure and more resilient GPS-like signal is really critical to people operating their business.
