A distinctive feature of SPIRIT Navigation approach is concurrent use of multiple technologies for indoor positioning. Measurements from such smartphone sensors as IMU (3D accelerometer, gyroscope), a magnetic field sensor (magnetometer), WiFi and BLE modules, together with the floor premises plan are used for hybrid indoor positioning in the navigation engine. Indoor navigation software uses such technologies as PDR, Wi-Fi fingerprinting, geomagnetic fingerprinting, and map matching. Being blended in a particle filter, dissimilar measurements allow solving a set of principal tasks. First, the navigation engine can automatically start in any place of a building wherever user switches on his or her smartphone. There is no need to enter initial position manually or to start outdoors where initial position can be determined by GPS/GNSS receiver. Then, operating in a tracking mode, the navigation engine provides a real-time indoor navigation for displaying current user’s position either on a floor plan or on Google Indoor Map if the latter is available for the building. At last, the navigation engine can recover tracking from failures that are the known problem of the particle filter occurring when all particles are accidentally discarded. The automatic recovery of tracking in this case allows continuing tracking and increasing the availability of indoor navigation. The navigation engine exits in a form of SDK that serves for building mobile applications both for Android and iOS. Positioning results given for different indoor environments in a shopping mall and in a big exhibition hall show fast TTFF indoors and accurate and reliable real-time indoor positioning with accuracy of about 1-2 m.

4. •Today indoor (WiFi-based) positioning accuracy 10-20 meters does not satisfy the needs of:
•Mobile marketing and advertising
•Rescue and emergency services
•Hyper local search indoors
•Geo-fencing and proximity informing
•Location Based Services require 1-meter accuracy
•Today users loose precise positioning and navigation ability at outdoor-indoor each time passing from the street into building
•Seamless outdoor-indoor navigation has to be provided
•Turn-by-turn navigation indoor is awaited feature
•Beacons infrastructure setup is expensive and takes time

For growing indoor LBS market
•Indoor Location-Based Services To Be the Next Multi-Billion Dollar Market Created by Smartphones
•Indoor Positioning: Mapping, Technology & Services GPS-based LBS (Location-Based Services) face a significant hurdle: 90% of people's time is spent indoors. As such, Indoor positioning offers significant potential for the LBS market
•ABI Research: the market of wireless location-based applications to reach $14.5 bln in 2014. Global Location Based Advertising Market to Reach $12.8 Billion by 2017
6. •Mapping, search and navigation to specific places, products on shelves, departments or sections, stores in a mall, etc
•Location-based promotions: When walking near a particular area, offer a coupon or discount on related items
•Location-based media & content: Display material based on the location, such as details on the place or item being seen
•Site analytics: Analyze where customers go, where they dwell, where more staff is needed, success of advertisements and displays, etc.
•List manager: Manage a shopping list and plan a route through a store
•Social services: Find friends, automatic check-ins, location sharing
•Find co-workers, meeting rooms, office equipment, etc., in an office
•GeoFencing: The ability to have actions happen (such as offering sales or issuing alerts) when the user goes close to specific locations
