De Geer moraine internal architecture based on sedimentological and geophysical investigations and implications for ice‐marginal reconstructions

Boreas, EarlyView.
De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.

A novel mode of INS-aided BDS real-time high-rate and precise kinematic relative positioning between two moving platforms

Geo-spatial Information Science
For kinematic relative positioning users between two moving platforms, limited communication bandwidth and computation ability usually cannot support real-time transmission of high-rate (≥10 Hz) BeiDou Navigation Satellite System (BDS) data.

Open-Source Factor Graph Optimization Package for GNSS: Examples and Applications [PDF]

arXiv
State estimation methods using factor graph optimization (FGO) have garnered significant attention in global navigation satellite system (GNSS) research. FGO exhibits superior estimation accuracy compared with traditional state estimation methods that rely on least-squares or Kalman filters.

Relative sea‐level trends in southern Norway during the last millennium

Boreas, EarlyView.
Relative sea level in southern Norway has been falling since c. 7000 cal. yr BP, but modern tide gauge data show rising relative sea level since at least 1960 CE. In this study, peat cores from a shallow coastal basin were analysed, using a multiproxy approach, to reconstruct relative sea level trends over the last millennium and to identify the onset ...
