Positioning and navigation are obvious every time we open up a maps app, but timing is also a critical function of GPS — offering our smartphones and devices precision timing to ensure that compute processes are accurately synced.
As more of the economy relies on these systems, they have increasingly become a target of hackers through GPS spoofing. The government wants to create additional redundancy and resiliency in the sector and has explored using commercial alternatives to augment or backup parts of the GPS system.
