A Post-Processing Multipath/NLoS Bias Estimation Method Based on DBSCAN
SensorsPositioning based on Global Navigation Satellite Systems (GNSSs) in urban environments always suffers from multipath and Non-Line-of-Sight (NLoS) effects. In such conditions, the GNSS pseudorange measurements can be affected by biases disrupting the GNSS-

Deceleration of Relativistic Radio Components and the morphologies of Gigahertz Peaked Spectrum Sources [PDF]
, 1998 A relativistic radio component, which moves in a direction close to the sky plane, will increase in flux density when it decelerates. This effect is the basis for the qualitative model for GPS galaxies we present in this paper, which can explain their ...

Archaeological Prospection, EarlyView.ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Research on localization scheme of UWB in NLOS environment
Tongxin xuebao, 2008 A localization scheme via UWB suitable for NLOS was given and a TOA estimation based on the strongest path （SP） detection was proposed. The positioning operation between FS and MT was implemented when FS detected two strongest paths from different ...

Archaeological Prospection, EarlyView.ABSTRACT Megalithic landscapes in Southeast Iberia remain unevenly and insufficiently documented, particularly in rugged areas where traditional survey methods are limited. This paper addresses this gap by applying a multiscalar approach to the megalithic necropolises of the Fardes River (Granada, Spain), with the objective of detecting, documenting ...

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data
Archaeological Prospection, EarlyView.ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.
