Overview > Scope, notation rules, key terminology, and the overall structure of the mobile positioning infrastructure setup manual. ## 1) Document Information | Item | Details | | - | - | | Based on | ·GeoSpace and OneS1ght screens as of October 2026 | | Target device | ·AN-500 locator | | Audience | ·On-site installers and operators | | Version | ·v1.4 | **Version History** **v1.4** | Date | Main changes | | - | - | | 2026-10-08 | ·Added the Demo Kit guide (Preparation · On-Site Installation · Operation Check)·Reorganized Troubleshooting by symptom and added the procedure for adjusting locator positions after deployment is complete·Hardware Registration: added guidance for using an iPhone Personal Hotspot (tethering), when to provision, and when to use Factory Reset·Verification: added App Store installation steps; added the Mobile Positioning Data Lookup page and a Checking Collected Data section·Installation supplies: added the power-bank alternative (line tape and paper tape are now optional); added a checklist item for measured values when no floor plan is registered | **v1.3** | Date | Main changes | | - | - | | 2026-09-22 | ·Added the Applying Firmware OTA document (file registration, target selection, progress and result checks)·Added retry guidance to Hardware Registration for connection failure (device response timeout) | **v1.2** | Date | Main changes | | - | - | | 2026-09-18 | ·Updated for the redesigned verification app (auto-detected positioning, permission guidance, signal-lost screen, event log)·Added the organization-settings based Geospace integration in OneS1ght and the SDK key issuance and registration steps·Fully updated Space Management (zone editing): screen layout, zone creation, and zone event settings | **v1.1** | Date | Main changes | | - | - | | 2026-09-15 | ·Added the Hardware Registration step (provisioning with the GeoSpace Mobile app) and reorganized the manual into 8 steps·Added entering the actual plan size and verifying it with distance measurement·Added LED status definitions (top and bottom) | **v1.0** | Date | Main changes | | - | - | | 2026-08-21 | ·Initial version (based on screens as of August 2026) | ## 2) Scope and Assumptions This manual is written with the following assumptions. * The instructions are based on a setup with 4 locators placed at the corners of the detection area (a space of roughly 15 m × 15 m). If you use more locators or the space has an irregular shape, additional configuration may be required. In that case, contact [support@ones1ght.com](mailto:support@ones1ght.com). * This manual covers the downlink method (DL-TDoA) using mobile devices. In the downlink method, mobile devices receive signals sent by the locators and compute their own position. * The uplink method, which attaches tags to people or assets, uses different equipment and configuration and is not covered in this manual. ## 3) Terminology | Term | Description | | - | - | | Line of sight (LOS) | ·A state where signals travel in a straight line between the locator and the receiving device with no obstacles in between | | Detection area | ·The positioning area covered by the locators; positions are measured within this area | | Reference direction | ·The top edge that defines the orientation of the space, used when setting the plan orientation and the coordinate system | | Downlink (DL-TDoA) | ·A method where mobile devices receive signals sent by the locators and compute their own position | | Plan scaling | ·Matching distances on the plan image to real-world distances (m) | | Locator | ·A device mounted on a wall or tripod that transmits UWB signals | | Master locator (INP) | ·The locator that anchors signal transmission within a cluster·The master locator transmits first, the remaining locators (RES) follow in a fixed order, and the mobile device computes its position from the arrival-time differences of each signal | | Session ID | ·A value that identifies a cluster | | Simulation mode | ·A mode for exploring settings and features with a sample floor plan before a partner key is registered | | Reference point (0, 0) | ·The coordinate origin at the bottom-left corner when facing the reference direction | | Offset | ·The difference between the conceptual reference point (0, 0) and the coordinates on the plan. Occurs when the plan image includes wall thickness or margins | | Cluster | ·A unit that groups multiple locators into one transmission group | | Partner key (gpk\_) | ·An integration key issued in GeoSpace and registered in OneS1ght | | Provisioning | ·The process of configuring a locator's Wi-Fi with the GeoSpace Mobile app so it connects to and registers with the GeoSpace server | | Host | ·The locator's main unit. Handles boot, network, and server connection, and runs separate firmware from the internal UWB module | | GeoSpace | ·Software that aligns installed locator positions with building and floor plans, and manages information such as locator coordinates and event areas·Provides this information for use in the mobile SDK | | OneS1ght | ·A cloud service that analyzes and utilizes the positioning data collected through GeoSpace | | SDK key (ock\_sdk\_) | ·An authentication key used by the SDK in your application when calling the API | | Zone | ·An area drawn on the plan, used as the basis for enter, exit, and dwell events | ## 4) Overall Structure Set up the positioning infrastructure in the following order. Each step assumes the previous step is complete. | Step | Description | Environment | | - | - | - | | [1.
