Positioning

In the context of geospatial technologies, positioning refers to identifying an object's coordinates in relation to a reference system, typically using GPS, GNSS, Wi-Fi, Bluetooth, or sensor-based technologies.

Introduction

Types of Positioning (Geospatial Context)

  1. Global Positioning (Absolute Positioning)

    • Determines an exact location using latitude and longitude.
    • Example: GPS (Global Positioning System), GNSS (Global Navigation Satellite Systems).
       

  2. Relative Positioning

    • Determines location relative to another point (e.g., using reference stations).
    • Example: Differential GPS (DGPS), Real-Time Kinematic (RTK) GPS.
       

  3. Indoor Positioning

    • Determines location inside buildings where GPS signals may be weak or unavailable.
    • Example: Wi-Fi positioning, Bluetooth beacons, RFID, LiDAR mapping.
       

  4. Network-Based Positioning

    • Uses cellular networks to estimate a device’s location.
    • Example: Triangulation from cell towers.
       

  5. Satellite-Based Positioning

    • Uses GNSS satellites (e.g., GPS, GLONASS, Galileo, BeiDou) to determine location.
    • Example: Navigation apps, autonomous vehicle tracking.
       

  6. Visual & Sensor-Based Positioning

    • Uses cameras, LiDAR, AR, and AI to determine position based on the environment.
    • Example: Augmented Reality (AR) navigation, self-driving cars, drone mapping.
