This article will explain which and how indoor GPS or IPS works, why it's so valuable, and how it's changing the way companies manage their spaces and resources. Whether you're curious about finding things faster or simply want to know how indoor tracking technology works, read on to discover how it’s making a difference!

Introduction to Indoor GPS and Indoor Positioning Systems

When you think of GPS, you probably imagine using it to find directions outside, like going from your home to school or the park. However, GPS doesn’t work as well indoors, where walls and ceilings can block signals. This is where Indoor GPS or Indoor Positioning Systems (IPS) come in. Indoor Positioning System is a technology designed to locate objects or people inside buildings.

It’s especially useful in large places like hospitals, warehouses, and shopping malls, where finding things quickly can save time, improve safety, and increase efficiency.

What is Indoor GPS?

Indoor GPS is a system that works inside buildings to track the exact location of items, equipment, or even people. Unlike traditional GPS, which relies on satellites using GNSS, Indoor GPS often uses different technologies, like Bluetooth, Wi-Fi, or special sensors, to work effectively indoors. This way, it provides accurate locations in spaces where satellite signals are weak or blocked.

People in big facilities can always know where things are by using an indoor GPS tracker or indoor tracking device. This technology is becoming popular in many fields, such as healthcare, retail, and logistics. 

Indoor Positioning Systems (IPS)

Indoor Positioning Systems (IPS) are essential for businesses because they make it easier to track assets (like machines or tools), ensure employee safety, and boost efficiency in daily operations. Imagine a hospital where doctors and nurses need to locate medical equipment quickly in an emergency. With an indoor tracking system, they can easily find what they need without wasting time.

IPS is also valuable for improving employee safety. In large buildings, it helps facility managers keep track of everyone, so they can respond faster in emergencies. Additionally, IPS helps companies reduce costs by minimizing time lost by searching for misplaced items and allowing operations to run smoothly.

Why Doesn’t GPS Work Indoors?

GPS, or Global Positioning System uses Global Navigation Satellite System to track anything. This great for finding locations outside but faces problems indoors. When GPS signals try to reach inside buildings, they often get blocked by walls, floors, and other structures. As a result, traditional GPS devices struggle to give accurate locations indoors. This can be an issue for many indoor areas, like large hospitals, warehouses, shopping centres, and schools, where knowing the exact locations is very important. That’s why there’s a need for specialized indoor GPS systems.

Challenges and Limitations of GPS Indoors

Traditional GPS technology has several limitations when used inside buildings. Here are a few key challenges:

• Signal Interference: The walls, ceilings, and other structures in buildings can block GPS signals, making it hard for devices to receive accurate data. This interference weakens the signals, making GPS unreliable indoors.
• Density Impact: When there are many floors or thick walls, the signals weaken even more, causing location data to become less accurate. For example, in tall buildings or crowded areas, GPS signals may be unable to reach every part of the building.
• Repeaters Are Limited: Some places try to solve this issue by using signal boosters, called repeaters, to increase GPS signal strength. However, repeaters can’t fully solve the problem, as they can only cover limited areas and don’t always give precise locations.

These challenges highlight why traditional GPS isn't effective indoors, leading many businesses to adopt Indoor Positioning Systems (IPS) that use Wi-Fi, Bluetooth, RFID, or UWB for accurate indoor tracking.

But when it comes to indoor tracking, where traditional GPS falls short, the Tracki GPS tracker steps up with its unique combination of Wi-Fi and Bluetooth technology, providing accurate location data even in complex indoor spaces.
