Real-time Location Tracking Systems

Increase the value of your existing technology investments with precise location & asset tracking! Our suite of Leantegra solutions offers real-time locating systems (RTLS), location intelligence and robust location analytics for the mining industry to deliver high value for both open-pit and underground operations where safety poses extra challenges. Beyond a complete RTLS solution, we offer full integration with existing systems, optimisation, training and support services.

Ultra-Wide Band and BLE for real-time tracking


Our UWB and BLE products enable long-range and short-range RTLS systems with high precision accuracy and low power usage. They are well-suited for tracking asset location underground, in radio-frequency-sensitive environments, peer-to-peer fine ranging, and high-bandwidth communications.

PRODUCTS


One-dimensional location tracking for underground mines or factory tunnels using the reverse RTLS algorithm for BLE beacons

 

Main Advantages

  • Much lower costs, no cabling is needed for RTLS devices, good scalability for tracking thousands of workers.

Accuracy

  • 10-20 meters

Range

  • 60-80 meters

Scalability 

  • Good scalability – tracking thousands of workers per location. RTLS device density depends on the WLAN capacity only.

Power Consumption

  • Low-power BLE beacons, up to 5 years on a single battery charge.

Location tracking for underground mines or factory tunnels using one or two UWB RTLS anchors

Main Advantages

  • Tracking with sub-meter accuracy using one or two RTLS anchors. Less devices, less expenses.

Accuracy

  • Less than 1 meter

Range

  • 50-60 meters

Scalability

  1. Settings for longer range : 1 Hz rate – up to 120 tags, 5 Hz rate – up to 25 tags.
  2. Settings for higher density: 1 Hz rate – up to 800 tags, 5 Hz rate – up to 160 tags.

Power Consumption

  • The same as UWB TWR – constant 5V power supply is needed for RTLS anchors. RTLS tags are powered by the cap lamp accumulators.

Costs

  • Lower costs than typical 2D UWB RTLS installations, considering the lower amount of RTLS anchors.

Custom implementation of the double-sided TWR based on Qorvo/Decawave DW1000 chipset, suitable for 1D-3D RTLS

Main Advantages

  • The best location accuracy, suitable for 1D, 2D and 3D RTLS, including the collision avoidance scenarios.

Accuracy

  • Better accuracy than TDoA: 5-10 cm for static objects, 10-30 cm for moving objects.

Range

  1. Settings for longer range: best case LOS – 80 meters, worst case LOS – 60 meters.
  2. Settings for higher density: best case LOS – 50 meters, worst case LOS – 30 meters.

Scalability

  1. Settings for longer range : 1 Hz rate – up to 120 tags, 5 Hz rate – up to 25 tags.
  2. Settings for higher density: 1 Hz rate – up to 800 tags, 5 Hz rate – up to 160 tags.

Power Consumption

  • TWR tags must be recharged every 12-48 hours or powered via USB (e.g. Tag PRO).

Costs

  • Slightly higher costs than TDoA, considering that TWR tags must be recharged on a regular basis or need to have the USB power supply.

Custom algorithm for the asynchronous TDoA without clock synchronizations for RTLS anchors, suitable for 2D RTLS

Main Advantages

  • Much lower power consumption than TWR, better scalability than TWR. Good for long-term installations using batteries.

Accuracy

  • 30-50 cm for static objects, 50-60 cm for moving objects.

Range

  1. Settings for longer range: best case LOS – 80 meters, worst case LOS – 60 meters.
  2. Settings for higher density: best case LOS – 50 meters, worst case LOS – 30 meters.

Scalability

  • Better scalability than TWR:
    1. Settings for longer range : 1 Hz rate – up to 360 tags, 5 Hz rate – up to 75 tags.
    2. Settings for higher density: 1 Hz rate – up to 2400 tags, 5 Hz rate – up to 480 tags.

Power Consumption

  • TDoA tags consume approx. 50-80 times less power than TWR tags.

Costs

  • For the case of RTLS tags powered by accumulators or batteries – less expensive maintenance than UWB TWR.

Remote tracking and on-device indoor navigation for Android and iOS smartphones using BLE beacons and 2D RTLS

Main Advantages

  • Lower cost installation – only BLE beacons are needed for tracking smartphones. Indoor navigation for smartphones is available.

Accuracy

  • From 1 to 3 meters depending upon the density of BLE beacons.

Range

  • Up to 15 meters for RTLS using BLE beacons

Scalability

  • Good scalability – tracking thousands of smartphones per location. RTLS device density depends on the server capacity only.

Power Consumption

  • Low-power BLE beacons, up to 5 years on a single battery charge.

Costs

  • Low-cost system based on BLE beacons, lower than UWB costs.

RSSI-based tracking for BLE beacons and other BLE devices

Main Advantages

  • The lowest cost tracking using inexpensive hardware, such as Locator MICRO devices.

Accuracy

  • Room-level or zone-level tracking, approximately 3-4 meters accuracy when in range (up to 15 meters).

Range

  • Up to 15 meters

Scalability

  • BLE beacon scanning per room/zone is limited to 30-50 devices per second.

Power Consumption

  • Low-power BLE beacons, up to 5 years on a single battery charge.

Costs

  • Low-cost system based on BLE beacons and inexpensive RTLS anchors, such as Locator MICRO.
