User: Provides Current

Sensor data: Imagery, audio, (A-)GPS, compass, inertial measurements, radio signal strength, GNSS carrier phase,…

Historic Known position/orientation Sensor data: …

Relevant “Interesting information” System

Uses sensor data and history from user and others to match against database

Returns User’s (precise) current position/orientation Relevant “Interesting information”

Updates database
