Title:
DETERMING ENVIRONMENTAL CONTEXT FOR GNSS RECEIVERS
Document Type and Number:
WIPO Patent Application WO/2020/248200
Kind Code:
A1
Abstract:
Method and apparatus for determining environmental context for a Global Navigation Satellite System (GNSS) receiver using extracted statistical characteristic features of received GNSS signals, A trained computational model (machine learning) determines a specific environmental context of the GNSS receiver according to the set of characteristic features of the received GNSS signals. Multiple e.g. 3 outdoor environmental contexts can be accurately determined from the received GNSS signals without additional input from sensors.
