    These terms describe the spatial resolution of location finding devices:

    These terms describe the spatial resolution of location finding devices

    ● 3D positioning: Tracks targets in full Cartesian coordinates (X, Y, Z), enabling free movement in 3D space (e.g., drones or robotic arms).
    ● 2D positioning: Confines tracking to a planar surface (horizontal or inclined), ideal for floor-level asset monitoring.
    ● 1D positioning: Restricts movement to a linear path (e.g., conveyor belt tracking).
    ● 0D positioning: Detects presence/absence of a target within a defined zone (e.g., real-time location tracking for entry/exit monitoring).
    Optimal accuracy is achieved when the system’s positioning dimension aligns with the target’s actual movement (e.g., 3D RTLS technology for dynamic indoor navigation).

    ● Electric power & energy
    ● Petrochemical
    ● Public safety & law enforcement
    ● Warehousing & logistics
    ● Intelligent recreation
    Our uwb location technology and AOA fusion positioning enable real time location tracking across diverse scenarios, from high-precision asset monitoring to personnel safety management.

  • How Does Eforthink’s RTLS Ensure Safety Ranging and Collision Avoidance?

    +

    The system comprises two core location finding devices: a ranging base station and a ranging tag.
    In practical applications, the distance between base stations or between a base station and a Personnel Location Tag reflects the proximity of vehicles or personnel. When the distance falls below a preset safety threshold, connected alarms and tags trigger real-time alerts (voice and light) to prevent collisions, such as forklift accidents.
    The base stations perform mutual ranging, while tags range with base stations (but not with each other). Safety distances between nodes (base stations/tags) are configurable via tools. This RTLS real time location system ensures instant alerts for dynamic risk mitigation.
