AccuRTLS

AccuRTLS is an advanced solution for tracking and locating BLE devices, based on a powerful patented AoA (Angle-of-Arrival) technology platform for real-time tracking with sub-meter accuracy.
AccuRTLS uses powerful locators, with planar array antennas, that can calculate the direction of arrival (both elevation and azimuth angle) of the signal broadcasted by BLE devices. With the determined angle of arrival and known exact position of the antennas, the localization system computes the exact location of the BLE devices using advanced triangulation algorithms.
AccuRTLS uses standard BLE advertising packet broadcast; thus, it can be used with AoA tags and sensors, but also with BLE-enabled devices, like smartphones.

Features

Bidirectional communication The bidirectional wireless protocol allows to transmit downlink data to the tags.

Accuracy Algorithms based on angle of arrival (AoA) estimation provide sub-meter accuracy, even in complex environments.

Real-time location Provides real-time location updates with update frequencies and latencies in the order of one second.

Wired infrastructure AccuRTLS requires a fully wired infrastructure: reliable connectivity, but higher costs.

Integration HTTP/MQTT APIs enable simple, fast, and seamless integration with existing platforms and systems.

Ceiling antennas AoA technology requires the installation of antennas exclusively on the ceiling, for optimal tags visibility.

Architecture

• Fixed AoA antennas receive BLE packets from the tags. Each locator is capable to compute the direction of arrival of the incident signal from each BLE tag moving in the area. Both elevation and azimuth angles are computed. Thanks to advanced proprietary algorithms, each locator can simultaneously receive hundreds of tag signals.
  Antennas are connected through LAN/WLAN to a local server where the Positioning Engine is installed.
• Asset and wearable tags are wireless electronic devices that are applied to assets or worn by people to be tracked.
  Tags are active devices, equipped with a battery, capable of autonomously transmitting information (unique identifier and status information) to the locators, using AoA-specific BLE advertising packets.
• AccuRTLS SW suite includes Positioning Engine (PE) and APIs. PE is the core of the tracking system, and uses signal direction information for triangulation. PE receives data from the Locators, runs it through advanced positioning algorithms and provides standard JSON/REST – push/pull APIs that enable seamless integration with other systems and softwares.
  AccuRTLS also includes functions for remote configuration and commanding of tags and for locator monitoring.
