Real-Time Positioning for Safe, Intelligent Mining With Boliden and LKAB

Centimeter-Level Precision, 1,420 Meters Below the Surface

In mining environments, space is limited and conditions are unforgiving. Narrow tunnels, heavy machinery and constant movement leave no margin for error — especially when people and machines need to operate in close proximity. Without GPS, maintaining accurate, real-time awareness of every worker and vehicle becomes a critical challenge.

To address this, Boliden — owner and operator of the Kristineberg mine — is working together with mining company LKAB and NXP to explore a real-time location system (RTLS) for underground mining operations. The system uses ultra-wideband (UWB) technology to track the position of workers and machines with centimeter-level accuracy, even in complex, high-interference environments — supporting situational awareness and helping reduce collision risks.

At the core of the solution is NXP’s Trimension SR048 platform, which integrates high- precision ranging, secure communication and real-time processing into a single, application-ready system. The result: rapid safety responses and accurate positioning that enable the shift toward autonomous mining operations.

Trimension SR048: Industrial‑Grade UWB SoC for High‑Precision RTLS

Key Highlights

Key Highlights

Real-Time Positioning and Spatial Awareness: A UWB-based Safety RTLS enables continuous, high-precision tracking of workers and vehicles, providing a shared, real- time view of the environment for safer and more efficient operations.
Predictive Collision Avoidance: Continuous distance monitoring between people and equipment enables early risk detection and triggers automated safety responses when minimum safety thresholds are exceeded.
Centimeter-Level UWB Accuracy: UWB technology delivers precise ranging and positioning, maintaining accuracy even in environments with signal reflections and limited line-of-sight.
Safety-Compliant System Architecture: Designed with fault detection and automatic recovery mechanisms, the system ensures reliable operation in safety-critical environments.
Industrial grade reliability: The hardware is designed to operate across temperatures from -40°C to 115°C, while maintaining performance under dust, vibration, and continuous operation.
Standards-based safety interoperability: Real-time positions of vehicles and workers are shared thought an omlox hub interface, providing interoperability across different RTLS platform vendors.
