Weekly Takeaways-June 21-2022

Updated: Dec 1, 2022

Theme of the Week

Frozen in Time When GPS was first made available to the commercial world it offered a timing accuracy of 40 nanoseconds. This timing accuracy enabled early 4G LTE networks. Now, twenty years later, the timing accuracy has improved slightly to 30 nanoseconds. This is barely adequate for 5G networks. And it comes with a caveat: "This performance standard assumes the use of a specialized time transfer receiver at a fixed location." (Note: specialized = expensive). But 6G networks, efficient data centers, and quantum networks need better timing accuracy. Unfortunately, there are no plans to improve GPS beyond 30 nanoseconds. A new solution is needed.

The More You Know...

The Ukraine conflict has highlighted the value of commercial satellite communications. “In the hours before the invasion began on February 24, Moscow launched "AcidRain" against Viasat… a "wiper" designed to target Viasat modems and routers and erase their data before permanently disabling them.” Their expectation was that this cyber attack would wipe out the last of Ukraine's communications. But they did not count on the resiliency of Starlink and other commercial satellite operators. “Ukrainians' access to Starlink has "totally destroyed" Russian President Vladimir Putin's information campaign,” asserts Brig. Gen. Steve Butow from Defense Innovation Unit (DIU). This success has caught the notice of US officials. But China is also paying close attention. Chinese researchers recently published a paper describing ways to “disable or destroy SpaceX’s Starlink satellites if they threaten national security.” They are also working hard to build up their own space capabilities. A recent workshop led by the US Air Force, DIU, US Space Force, and NASA concluded that “China is on track to surpass the U.S. as the dominant space power as early as 2032,” and “has already surpassed the U.S. in some key areas closely related to space, e.g. quantum, hypersonics.”
