Advanced Navigation
Advanced Navigation is a Sydney-based deep-technology company building navigation and autonomy systems that let robots, ships, aircraft, submarines and spacecraft know where they are when GPS is jammed, denied or simply unavailable. Founded in 2012 by Xavier Orr and Chris Shaw to commercialise AI-based inertial navigation research, it now designs and manufactures fibre optic gyroscopes, MEMS inertial sensors, underwater acoustic positioning and a miniature autonomous underwater vehicle across defense, space, marine, mining and commercial markets. In March 2026 it raised US$110M in Series C funding to accelerate its expansion into photonics, AI and quantum sensing.
Higher Ground LLC
Higher Ground LLC is a Palo Alto hardware startup that builds compact, secure satellite communication and navigation devices. Its flagship SatPaq turned a smartphone into a two-way satellite messenger by talking to geostationary Intelsat Galaxy satellites, and the company has since pivoted its expertise toward defense and government work - most notably GEOFix, a non-jammable backup to GPS. Led by founder and CEO Rob Reis, the company holds dozens of patents and counts the U.S. Department of Defense, DHS, NASA and the FAA among its customers.
Brian Manning
Brian Manning is the co-founder and CEO of Xona Space Systems, a Burlingame, California startup building Pulsar, a commercial alternative to GPS broadcast from a planned 258-satellite constellation in low-Earth orbit. A former SpaceX engineer who worked on the Falcon 9 thrust structure, Manning reunited eight Stanford aerospace graduates over pizza and beer in 2019 to chase a question nobody had answered: why has no one built a private, encrypted, centimeter-accurate navigation network? In 2022 Xona launched Huginn, the first commercial satellite navigation mission in orbit, and in March 2026 closed an oversubscribed $170 million Series C to scale manufacturing and begin deploying production satellites.
Xona Space Systems
Xona Space Systems is a Burlingame, California company building Pulsar, a commercial low-Earth-orbit constellation that delivers positioning, navigation, and timing (PNT) with centimeter-level accuracy, signals far stronger than legacy GPS, and built-in authentication to resist jamming and spoofing. Founded in 2019 by Stanford and SpaceX alumni, Xona aims to deploy roughly 258 satellites that work with existing devices through software updates, offering a resilient alternative and augmentation to government-run satellite navigation systems.
