Locator PRO
from $250
Locator PRO is a feature-rich anchor and gateway device for industrial RTLS networks. It was designed and developed for both indoor and outdoor installations in industrial environments, such as metallurgical factories and warehouses.
The device is compliant with IP67 requirements and includes all typical interfaces and connectors, which are needed for enterprise-grade installations at your locations – for example: 802.3at-af PoE, WLAN and USB interfaces.

RTLS Technologies
- UWB for 1D-3D RTLS scenarios based on TWR and our custom algorithm with 5-10 cm accuracy.
- Tunnel UWB/BLE RTLS algorithms, which were developed specifically for underground mines.
- Custom UWB TDoA algorithm for highly scalable and low-power 2D RTLS scenarios, which need 50-60 cm accuracy for RTLS.
- BLE zoning based on RSSI and Kalman filtering - suitable for room-level tracking scenarios.
- Height tracking based on the embedded barometer - suitable for floor/level detection with less RTLS anchors.
- Sensor telemetry for RTLS tags over UWB or BLE payloads - accelerometer, gyroscope, temperature (see Chapter 6.8).
Multiple Connectivity Options
Connect using Ethernet LAN, POE, WLAN, USB or special options such as the Sealed Mode and the custom Wi-Fi Mesh network.
