On August 21, 2025, a U.S. military space plane, the X-37B Orbital Test Vehicle, is scheduled to launch its eighth mission. Though a few additional things are still classified, one experiment in particular has captured the imagination: a quantum inertial sensor meant to serve as a major new alternative to GPS. This would revolutionise navigation in areas where satellite-based systems are not available or have been degraded. Whether in deep outer space, under the sea, or in hotspots on land, there is an eagerly awaited answer for vulnerabilities in global positioning systems. X-37B Space Plane to Pioneer Quantum Navigation as GPS Alternative in Space According to reports, satellite GPS powers everything from civilian smartphones to commercial aviation, but it has critical weaknesses. Signals degrade in space, can't get through water, and are subject to jamming and spoofing in contested environments. Researchers said the X-37B's quantum inertial sensor relies on atom interferomet...
