Australia emergency services prepare for GPS blackouts
Australian emergency and defence personnel are being trained in analog navigation and communication methods as experts warn satellites and other space systems could be vulnerable to disruption
Australian emergency services and defence personnel are being taught how to work without the satellite systems that now support much of modern life, with training that includes paper maps, terrestrial navigation and even sextant use for navigation by the stars.
How will Australia s emergency services cope if satellites go down?
The question is no longer being treated as a remote hypothetical. According to The Guardian, personnel in Australia are already being prepared for the possibility that space-based infrastructure could be disrupted, affecting navigation, communications and other services that depend on satellites.
At the centre of the discussion is the growing reliance on systems many people barely notice in daily life. GPS supports route-finding and coordination. Remote sensing helps provide information from above. Secure communications underpin many official and operational tasks. If those systems were unavailable, the impact would not be limited to one sector.
That concern was highlighted at the 19th Australian Space Forum in Adelaide on Wednesday, where a panel was asked to consider what would happen if access to critical space infrastructure were suddenly lost. The scenario discussed included no satellites, no GPS, no remote sensing and no secure communications.
Experts at the forum warned that Australians may not fully appreciate how dependent they are on space-backed technology. They also pointed to two broad sources of risk: hostile action and solar flares. In that context, the issue is not simply one of convenience, but of resilience.
Nick Leake, who heads Optus satellite and space systems, said the threat should not be dismissed as science fiction. His comments pointed to a chain reaction that could touch multiple parts of public life. He said ATM networks could go down, emergency services could lose situational awareness and aircraft navigation could be affected.
Training for a satellite-free environment
The practical response described in the report is a return to basic methods that predate the GPS era. Military and State Emergency Service personnel are being taught to read paper maps, navigate without satellite support and use terrestrial navigation techniques. The Defence Force is also offering sextant training, allowing members to navigate using the stars.
That kind of preparation reflects an effort to make sure key teams can still operate if digital systems fail. For emergency services, situational awareness can be crucial when responding to incidents, moving resources and coordinating across large areas. For defence personnel, loss of positioning and communications tools could complicate planning and movement.
The emphasis on analog methods does not mean satellites are expected to fail imminently. But the training shows that authorities and industry experts are treating the possibility seriously enough to prepare for it now. That is important because the systems in question are woven into transport, finance, communications and emergency response.
The forum discussion also underscores a broader policy issue: resilience. As Australia expands its use of space-based systems, the challenge is not just access, but continuity. The more services depend on satellites, the more disruptive any outage could be.
Why the warning matters
The warning from Adelaide matters because it connects abstract space infrastructure to everyday systems that people rely on without noticing. ATM networks, aircraft navigation and emergency response all depend, directly or indirectly, on technology in orbit. A disruption would not stay confined to one agency or one device.
That makes the current training more than a historical curiosity. Paper maps, sextants and street directories may seem old-fashioned, but they are part of a contingency plan for a world where satellite dependence is no longer a given.
What happens next was not detailed in the supplied material. But the message from the forum is clear: Australia is already preparing for a future in which emergency services and defence may need to keep operating when space systems are unavailable.
