Abstract
Abstract. This work addresses the challenge of multipath interference in Global Navigation Satellite System (GNSS) positioning. An approach is proposed to improve accuracy through adaptive weighting strategies and multipath isolation techniques. Weighting methods based on elevation and carrier-to-noise ratio (C/N0) are employed, and this strategy is combined with a multipath detection technique using the Code-minus-carrier (CMC) rate of change. The method is tested using a Piksi Multi GNSS Module, with data processed using Standard Point Positioning (SPP) techniques. An 8-state filter based on a Position-Velocity (PV) model is implemented for dynamic state estimation. Experiments in static and dynamic scenarios demonstrate significant improvements in positioning accuracy.
This study explores methods for precise attitude estimation using carrier phases within global positioning systems (GPS). Carrier phase data is preferred over pseudorange data for short baseline distances due to its lower noise levels. However, resolving ambiguities through integer ambiguity resolution methods is essen...

Accurate positioning of Global Navigation Satellite System (GNSS) is essential for civil applications but degrades in harsh environments, especially in vegetated environments. While building impacts on GNSS performance are well-studied, vegetation effects remain poorly characterized. Although existing studies have anal...

In two-station 3-D passive source localization, combined angle of arrival (AOA) and time difference of arrival (TDOA) methods often exhibit performance degradation at low signal-to-noise ratios (SNRs). To address this issue, this letter first derives an error propagation model and demonstrates the limitations of the co...
Global Navigation Satellite Systems (GNSS) provide essential positioning, navigation, and timing (PNT) services for a wide range of safety-critical applications. However, GNSS performance degrades significantly in satellite-deficient or interference-prone environments. To address this limitation, this study proposes a...
