SYSTEMS AND METHODS FOR DETERMINING NETWORK ACCESS POINT LOCATIONS

摘要

A positioning method for a mobile platform includes acquiring GPS position data associated with the mobile platform from a plurality of GPS satellites observable by the mobile platform. A set of wireless range measurements associated with the mobile platform and a plurality of wireless access points in communication with the mobile platform are received (e.g., via time-of-flight measurements). Wireless position data associated with the plurality of wireless access points is received from a server communicatively coupled to the mobile platform over a network. A corrected position of the mobile platform based on the wireless position data, the wireless range measurements, and the GPS position data.

主权项

1. An access point position learning method, comprising:
acquiring first GPS position data associated with a first mobile platform; acquiring a first wireless range measurement associated with the first mobile platform and a wireless access point in communication with the first mobile platform; determining a first estimated position of the wireless access point based on the first GPS position data and the first wireless range measurement; acquiring second GPS position data associated with a second mobile platform; acquiring a second wireless range measurement associated with the second mobile platform and the wireless access point; and determining a second estimated position of the wireless access point based on the first estimated position, the second GPS position data, and the second wireless range measurement.
