V2X technology has dominated conversations around mine vehicular safety for years. This vehicle-to-everything communication system currently stands as the most promising solution for reducing the thousands of injuries or fatalities that occur on mine sites each year. 

Yet, today’s most common V2X systems rely on a technology that actually hinders their full potential for safety in a live mining environment: low-fidelity positioning.

Low-precision GNSS provides V2X systems with positional accuracy within five metres of their actual geolocation — relatively close, but not nearly accurate enough to evade the nuisance alarms that bother operators working in normal and safe proximities. Users of low-precision V2X systems routinely complain of these nuisance alarms, eventually learning to distrust the alerts, become complacent, or turn the system off completely. 

Options are available to resolve this problem, though. Cameras and lidar are two technologies used in mining V2X that reliably improve safety outcomes, albeit with drawbacks. Now, a third solution is making inroads as an effective means of improving proximity detection without the complications of either camera or lidar systems: high-precision GNSS.
