A radionavigation subsystem of a mobile device can determine a first location estimate of the mobile device. The mobile device can determine a free direction from the first location estimate. The free direction can be a direction along which RF signals may cause greater position errors than RF signals from other directions may cause. The mobile device can determine a potential outlier among the received RF signals, the potential outlier being an RF signal from a signal source in the free direction. The mobile device can indicate to the radionavigation subsystem that a weight of the potential outlier shall be reduced when determining a second location estimate of the mobile device using the RF signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"De-weighting of outlier signals in a radio frequency navigation system","description":"Methods, systems and computer program products for determining and filtering potential outliers in RF signals used in radionavigation are described.
