POSITIONING OPERATION BASED ON FILTERED MAP DATA - A simplified explanation of the abstract

This abstract first appeared for US patent application 18330424 titled 'POSITIONING OPERATION BASED ON FILTERED MAP DATA

Simplified Explanation

The patent application describes a system where a user device or server can obtain the position of the user device using GNSS or sensor-based trajectory, filter map data to find possible routes based on criteria, and determine a position estimate for the user device.

  • User device or server can obtain GNSS position or sensor-based trajectory of user device
  • Map data is filtered based on criteria associated with GNSS position or sensor-based trajectory
  • Position estimate for user device is determined based on filtered map data

Potential Applications

  • Navigation systems for vehicles or pedestrians
  • Location-based services for mobile applications
  • Emergency response systems for tracking individuals

Problems Solved

  • Improving accuracy of position estimates
  • Providing better route recommendations
  • Enhancing user experience with location-based services

Benefits

  • Increased efficiency in navigation
  • Enhanced safety with accurate position estimates
  • Improved user satisfaction with personalized route recommendations


Original Abstract Submitted

In an aspect, a user device or a server may obtain a global navigation satellite system (GNSS) position of the user device, a sensor-based trajectory of the user device, or both. The user device or the server may filter map data indicating possible routes of the user device based on one or more criteria associated with the GNSS position, the sensor-based trajectory, or both to obtain filtered map data. The user device or the server may determine a position estimate for the user device based on the filtered map data.
