Navigation in Multi-Story Buildings made Easy



You probably think creating an indoor navigation platform like Mapsted is easy. Well, you’re sadly mistaken. Creating a platform as advanced and diverse as ours is very difficult because we implement and develop technology that has never been seen before. No matter how difficult, we find a way to make it possible.  For example, designing technology that accurately pinpoints users’ location in a large multi-story building. At the moment, none of the frequently-used platforms ensure precise device targeting in multi-story buildings such as airports or universities.  


GPS is a great solution for outdoor positioning, but when it comes to indoor locations, the results fail to deliver. Physical obstacles interfere with the satellite signal. Other platforms such as beacons, kiosks, and visual markers don’t make the situation any better. Each of the other location-based services have substantial shortcomings that prevent them from precisely determining the location of people indoors. 


We realized this problem and developed an indoor GPS platform that successfully identifies the position of users in multi-story facilities. We were awarded a patent for indoor wayfinding in large facilities with multiple stories. The patent recognizes systems and methods for determining indoor location and floors of a mobile device. 


If you want to check it out for yourself the patent number is- US9961508B1.




For this feature to work properly, the indoor positioning platform requires: 


  • A mobile device that has a processor and a memory

  • At least one wireless signal data to measure signal strength and determine at least one potential location of the device for each floor 

  • A map constraint feature or a heading determined in accordance with device sensor data

Basically, we identify the most likely position of the device based on wireless signal data, step information, and anticipation data. 


The wireless signal comes from Bluetooth or Wi-Fi, while step information includes inputs on length and heading. Anticipation data is covered by routing information, map limitations, and device movement history. 


Our invention is the foundation for the floor detection in multi-story building indoor navigation systems. The platform makes use of all data available to figure out the phone/floor transition in all situations. This is exactly what makes our technology so great- it functions flawlessly even in the case of floor transitions using stairs, elevators, and escalators. 


Mapsted indoor navigation relies on the four-step mechanism: 


  • A map importing module take a floor map of an indoor space and processes it for further use. 

  • A calibration module creates a fingerprint map of the building described by the floor map 

  • A floor localization module searchers the fingerprint map of every floor to determine the most likely location for each story. 

  • A floor detection module combines the most likely location for each story, map limitations, and device movement data to determine the floor and location
