High-Precision GPS Tracker featuring u-blox M10

Client

An innovative None technology firm pushing the boundaries of edge computing and reliable connectivity.

Challenge

Achieving sub-meter positioning accuracy for asset tracking while operating on a non-rechargeable battery for 3 years.

Product Concept & Architecture

The hardware architecture is centered around the u-blox M10 + STM32L4. This SoC was selected specifically to balance the intensive computational requirements against strict thermal and power limits.

Engineering Solution

Paired the ultra-low-power STM32L4 MCU with the u-blox M10 GNSS module. Implemented an aggressive deep-sleep duty cycle in FreeRTOS. The system only performs cold GPS starts when the onboard IMU detects sustained movement, extending battery life drastically.

Result

The product passed all regulatory compliance testing (CE/FCC/RoHS). Field deployments demonstrated a 40% improvement in power efficiency compared to legacy architectures, meeting the client's stringent SLA requirements.
