Evaluation of Tropospheric and Ionospheric Effects on Arctic Navigation Conditions

S.C. Barth Diener

Abstract:	The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) dataset is evaluated and compared with the JPL GPS Receiver Station Network for use in monitoring and forecasting (simulation/evaluation) tropospheric and ionospheric conditions for GNSS navigation in the arctic maritime environment. Challenges in navigating through arctic seas and harbors include reduced GPS signal availability, increased multi-path and loss-of-lock potential, and changing seasonal coastlines amidst internationally disputed claims to water passageways. Mitigation techniques using auxiliary weather data are explored under degraded arctic GNSS conditions.
