Sean Kirkpatrick, director of the Pentagon’s All-domain Anomaly Resolution Office, wrote in a research titled “Physical Constraints on Unidentified Aerial Phenomena” and co-authored by Abraham Loeb, chairman of Harvard University’s astronomy department that there is a possibility that extraterrestrial motherships and smaller probes may be visiting Earth and other planets in our solar system.
The Pentagon is literally talking about the existence of alien motherships that release probes to earth.
“An alien mothership could potentially be a parent craft that releases many small probes during its close passage to Earth. In their research paper they suggest that 'Oumuamua' is possible such a mothership with probe capabilities.
These tiny probes would reach the Earth as the mothership passes by within a fraction of the Earth-Sun separation, just like ‘Oumuamua’ did,” the authors explained. Astronomers would not be able to notice the spray of mini-probes because they do not reflect enough sunlight for existing survey telescopes to notice them. source.

Europe’s Galileo is the world’s most precise satellite navigation system, providing metre-level accuracy and very precise timing to its four billion users. An essential ingredient to ensure this stays the case are the atomic clocks aboard each satellite, delivering pinpoint timekeeping that is maintained to a few billionths of a second. These clocks are called atomic because their ‘ticks’ come from ultra-rapid, ultra-stable oscillation of atoms between different energy states. Sustaining this performance demands, in turn, even more accurate clocks down on the ground to keep the satellites synchronised and ensure stability of time and positioning for users.

Would you like to know the future of satellite navigation? Try ESA’s Navigation Laboratory. This is a site where navigation engineers test prototypes of tomorrow's user receivers, using simulated versions of the navigation signals planned for the coming decade, such as set to be transmitted from Galileo’s Second Generation satellites.
