From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise timing signals from satellites. Known as the Global Navigation Satellite System (GNSS), satellites carrying atomic clocks transmit time-stamped signals to receivers on Earth. The Global Positioning System (GPS) is the best-known GNSS in Australia and the United States, but it is only one of several systems used globally.
The increasing reliance on precise timing signals for critical infrastructure, coupled with the inherent vulnerabilities of current satellite navigation systems, is driving innovation in more secure quantum alternatives.
Securing satellite timing through quantum entanglement could significantly enhance the resilience and trustworthiness of essential services that underpin modern economies and national security, making them less susceptible to spoofing or jamming.
The fundamental method of broadcasting and receiving precise timing signals could evolve, moving from easily interceptable radio waves to more secure quantum-secured channels, reducing vulnerabilities in critical infrastructure.

Enhanced security for critical national infrastructure reliant on satellite timing, such as power grids and financial networks.
Increased investment in quantum communication technologies and a more rapid development of quantum internet infrastructure globally.
New geopolitical dynamics where control and access to quantum-secured timing and communication become strategic assets, potentially leading to 'quantum alliances' or new forms of digital sovereignty.
