Configure indoor positioning

A global positioning system (GPS) is widely used to determine a location anywhere in the world. It works best where there is an unobstructed line of sight to four or more satellites. This results in relatively weak signals inside structures such as buildings. An indoor positioning system (IPS) is used to determine a location inside buildings by taking advantage of infrastructure such as Wi-Fi access points that are present at fixed locations and transmit signals.

There are several commercial systems available that use various technologies, including Wi-Fi and Bluetooth, for providing IPS. Vendors of such systems need to survey the interior space of buildings to enable indoor positioning. The precision of indoor location is dependent on the technology used. Bluetooth-based IPS is generally more accurate and reliable than Wi-Fi-based IPS.

ArcGIS Indoors for iOS supports Wi-Fi-based indoor positioning provided by Apple, and Bluetooth-based indoor positioning provided by Indoo.rs.

Mobile operating systems have location service specific settings that play a factor in getting the most accurate positioning in an indoor space. The following setting is recommended for a good IPS experience:

  • Turn on the Location Services setting and set Location to Always to allow location access.
    iOS Location Services
    iOS Location Access

If your organization is using Indoo.rs IPS, the mobile map packages must include a specific set of configuration related to it. For more information, see Configure the indoor positioning system.
