An Indoor Positioning and Navigation System (IPNS) is a technology solution designed to help people and assets find their exact location inside buildings where GPS signals are weak or unavailable. While outdoor navigation has become easy with satellite-based GPS, indoor environments such as shopping malls, airports, hospitals, warehouses, universities, and large office complexes still present major challenges. Indoor positioning systems solve this problem by using a mix of wireless technologies, sensors, and digital maps to provide real-time location tracking and guidance.
Indoor navigation works by collecting signals from different sources such as Wi-Fi access points, Bluetooth beacons, RFID tags, ultra-wideband (UWB) devices, or even magnetic field mapping. These signals are analyzed to determine the user’s position within a building. Once the system identifies the location, it can guide the user to a destination using step-by-step directions, similar to how Google Maps works outdoors. The main difference is that indoor navigation requires much more detailed mapping and signal accuracy because indoor spaces have multiple floors, walls, and obstacles that can interfere with signals.
