Weekly Takeaways-May 10, 2022

Theme of the Week

Turning a Supertanker Requires a Tug Boat Last week the National Space-Based Positioning, Navigation, and Timing Advisory Board held their semi-annual meeting. The 29 non-government GPS experts met to provide “independent advice to the U.S. government on GPS-related policy, planning, program management, and funding profiles.” They also acknowledged the challenge of effecting change. The fundamental problem is that GPS is critical to many stakeholders with different needs. The Open PNT Industry Alliance (OPIA), another GPS advocacy group, took a different tack. Their 21 corporate members released a statement recommending an alternative solution leveraging commercial technology. There is finally a realization that commercial companies “can move with the speed and urgency that the DoD now requires” and “national security is inexorably intertwined with commercial technology."

The More You Know...

How did GPS get to a dominant position in commercial receivers for the world? GPS came first, but there are newer navigation systems like Galileo, BeiDou, and QZSS that claim to offer better accuracy. The majority of consumer devices contain a chip that acquires GPS first, then may use other signals to better hone their accuracy. GPS has a C/A code that "is almost perfectly designed for good acquisition sensitivity...that’s why GPS dominates the GNSS landscape." When a positioning device (like your smartphone) connects to a network, the additional data provides assisted positioning from these other sources. But Moore's law is in effect - as processing power gets cheaper, GPS leadership may be ceded to these other sources.
