Research on the Improvement of GNSS Performance and Development of Performance Evaluation Technology in Low Magnetic Latitude Regions

Satellite navigation (GNSS) is affected by various phenomena on the paths through which radio waves propagate. In the low magnetic latitude region where Japan is located, high ionospheric activity is one of the limiting factor of GNSS performance for air navigation. We utilize space weather information to enhance safety and availability of air navigation systems in the low magnetic latitude region.
