✍️ Theme of the Week

Timing is Everything
GPS was borne out of the space age nearly a half a century ago.
But for two decades we have known that something better is needed.
Timing from GPS is good enough for 4G LTE, but only barely good enough for 5G and not nearly accurate enough for 6G.
Now, with the advancement of four core technologies, the conditions are finally ripe for a replacement:

  1. Cheap access to space
  2. Commercial quantum communication systems
  3. The golden age of atomic clocks
  4. Ubiquitous space-based optical communications hardware

The need for a better global timing system has been around since networks went digital.
But you can't bake the perfect cake until the ingredients are ready.
Timing is everything.

🎓 The More You Know...

All networks rely on timing from GPS. So what happens when GPS goes down?
Well, you hope it comes back online. And quickly.
An extended outage would result in the degradation, then loss, of all financial transactions, communications, and eventually power.
If you want your networks to last more than a few hours, you need to build in resiliency against an outage, known as holdover.
And that can get expensive.
There are a number of ways to do this, but they all rely on adding in multiple additional sources of timing independent of GPS.
For example, you can add in very stable clocks, spatially separated GPS receivers, or equipment that can receive timing signals from other GNSS satellites (like BeiDou or Galileo) throughout the network.
But that requires the expense of additional hardware as well as designing a timing network.
