TDK launches STRIDE low-power, real-time positioning software for wearables and IoT

TDK Corp. announced Trusted Positioning STRIDE, an embedded Pedestrian Dead Reckoning (PDR) software solution engineered specifically for wearables -- including smart watches, head-mounted devices, glasses, and compact sensors.

As OEMs push for more intelligent, context-aware wearable experiences, STRIDE provides reliable positioning without the power and hardware demands traditionally required for GNSS-based tracking.

Wearables today face a critical challenge: adding high-quality positioning typically requires bulky antennas, high-drain GNSS, or costly custom hardware—barriers that limit form factor, battery life, and user experience. STRIDE overcomes these constraints with a low-power, sensor-agnostic software engine that fuses inertial data with GNSS and opportunistic wireless signals, delivering continuous location tracking indoors, outdoors, and everywhere in between.

“Wearable devices demand positioning that is compact, efficient, and dependable—without sacrificing battery life,” said Chris Goodall, President of Trusted Positioning. “With STRIDE, OEMs can integrate real-time indoor/outdoor positioning into devices of all shapes and sizes. It enables smarter fitness products, safer lone-worker solutions, more immersive AR experiences, and wearable-driven applications that were previously impossible due to power or hardware limitations.”

STRIDE runs as embedded software, giving OEMs freedom to deploy positioning without redesigning hardware or relying on cloud connectivity. STRIDE processes sensor data in real time, ensures low latency, and can be configured for on-device, companion-device, or cloud-assisted architectures. This flexibility helps manufacturers balance performance, power, and form-factor constraints based on their device strategy.
