Performance characterization of a new, low-cost multi-GNSS instrument for the cryosphere
Abstract We developed a multi-frequency, multi-Global Navigation Satellite System (GNSS) positioning instrument optimized for autonomous applications in the cryosphere. At lower power requirements and a fraction of the cost and weight compared to commercially available options, this instrument simpl...
