Z-Axis Measurement in UWB RTLS

Status:  BETA

Nowadays, it is already proven that X-Y coordinates can be obtained from UWB RTLS system with sub-meter accuracy even in harsh industrial environments. Nevertheless, estimation of Z coordinate is still challenging and always needs to be considered based on given use-case.

There are two common techniques to deliver Z-axis either via barometric measurement or via UWB signal. Let us discuss both in greater detail.

• Z-axis based on barometer
• Z-axis based on UWB signal
