Inkwater expands into GPS-denied positioning

Inkwater Holding Inc. says it is pushing beyond outdoor GPS into “Last-Meter Positioning” for indoor and other GPS-denied environments, aiming at airports, transportation hubs and Physical AI systems. The company says the infrastructure-free technology can work without beacons or new hardware and has already been deployed at Singapore Changi Airport and other large sites.

Why it matters: - Inkwater is targeting the gap between outdoor GPS and indoor navigation, where satellite signals weaken or disappear. - The company says that gap matters for people, vehicles and robots moving through airports, hospitals, factories, tunnels, shopping centers and other large buildings. - A positioning layer that works without dedicated venue hardware could reduce deployment costs and expand location services into more places. - The company also sees the technology as a foundation for Physical AI, autonomous systems and location-based safety.

What happened: - Inkwater Holding Inc. announced an expansion of its technology strategy into next-generation positioning, navigation and Spatial Intelligence. - The company calls the challenge “Last Meter” positioning: the missing layer between satellite navigation and GPS-denied environments. - Inkwater says the technology uses wireless signals already present in the environment plus sensing on endpoint devices. - The company says the system does not require beacons, UWB anchors or other new positioning hardware. - The underlying technology has been deployed at Singapore Changi Airport, Tokyo Station and major commercial complexes in China.

The details: - Inkwater says traditional indoor positioning often depends on Bluetooth beacons, UWB anchors, RFID or other dedicated infrastructure. - The company says wireless fingerprinting can require manual site surveys, signal mapping and recurring recalibration. - Inkwater says its architecture is self-optimizing and improves as it gathers more real-world usage and environmental data. - The company says the goal is to reduce dependence on recurring manual fingerprint collection. - Inkwater says the technology is designed for continuous guidance from outdoor GPS environments into indoor spaces. - The company argues that vertical location, or the Z-axis, can be as important as X-Y coordinates in multi-level buildings and transit systems. - Chairman I-Fa Chang said GPS did not complete the “last meter” of positioning and that location awareness should not disappear when satellite coverage does. - Chang said the opportunity is to extend positioning into GPS-denied environments without requiring every venue to install beacons or rebuild infrastructure. - Dr. Jiangsen Tian, chief AI scientist of Yushan AI and a former vice president of Microsoft Research Asia, said deployment cost and infrastructure burden have been major barriers to mass-market indoor positioning. - Tian said the ability to continuously optimize positioning error could make the system important from both a technology and commercialization standpoint. - Allen Chiu, head of business development, said scalable positioning should not require every venue to deploy a new layer of dedicated infrastructure.

Between the lines: - Inkwater is positioning the product as more than an indoor navigation tool. - The company is framing it as a bridge from mapping to spatial intelligence, with possible uses in robotics, transportation, healthcare, smart buildings, warehouses, search and rescue and drones. - That framing tracks a broader industry shift as AI systems move from screens into physical environments and need continuous awareness of location. - The company also points to potential dual-use applications, while saying regulated markets would be evaluated under applicable laws and export-control requirements.

What's next: - Inkwater plans to keep integrating artificial intelligence, wireless sensing, positioning, navigation and Spatial Intelligence technologies. - The company says it will explore commercialization and strategic collaboration opportunities across global mapping, Physical AI, intelligent mobility, robotics, smart infrastructure, low-altitude applications and aerospace. - Inkwater also intends to explore synergies between Yushan AI’s AI and Edge AI capabilities and its Spatial Intelligence strategy. - The company’s longer-term vision is for intelligent devices to answer three questions: where am I, what is around me and what should I do next.

The bottom line: - Inkwater is betting that the next big location-services breakthrough is not better outdoor GPS, but reliable positioning after GPS stops working.
