In the beginning, GPS was envisioned as a military program. A sign on the wall in the Joint Program Office where the systemcame into being during the early 1970s read: “The mission of this Program Office is to:
A Department of Homeland (DHS)-chartered May 2021 report concludes that PNT threat and resilience concerns are not as dire as some have made them out to be, and that funds for backup could be spent elsewhere. Why this runs counter to other recent government reports is not clear, nor is the fallout from this divergence of Congressionally mandated views. The Department of Transportation has distanced itself a bit from this report by the RAND Corporation—and even its issuer, the DHS, seems to have done so.
A European consortium led by the French map service provider GEOSAT will investigate how the combination of self-driving mapping cars — or autonomous mobile mapping systems (AMMS) — and artificial intelligence-based mapping software can automate the production of high-definition (HD) maps.

NASA’s Deep Space Atomic Clock is working toward giving far-flung space explorers more autonomy when navigating. In a new paper published in the journal Nature, the mission reports progress in their work to improve the ability of space-based atomic clocks to measure time consistently over long periods.
