    High-Precision UAV Photogrammetry with RTK GNSS: Eliminating Ground Control Points by Mehmet Nurullah Alkan

    Published 2024-12-01
    “…However, RTK-embedded UAVs offer a significant improvement by facilitating direct geo-referencing of DTMs, which includes the estimation of internal and external orientation parameters more efficiently and potentially eliminating the need for GCPs.In this study, UAV flights over a test area at various altitudes (30m, 45m, 60m) were conducted to evaluate the 3D positioning accuracy of photogrammetric models generated without using any GCP, and their locations were compared against the precise GNSS observations for 22 control points. …”

    Weak magnetism of Martian impact basins may reflect cooling in a reversing dynamo by S. C. Steele, R. R. Fu, A. Mittelholz, A. I. Ermakov, R. I. Citron, R. J. Lillis

    Published 2024-08-01
    “…In particular, if the magnetic properties of the Martian mantle are similar to most Martian meteorites and late remagnetization of the near surface is widespread, >90% of large ( > 800 km diameter) basins would appear demagnetized at spacecraft altitudes. This ultimately implies that Mars’s apparently demagnetized basins do not require an early dynamo cessation. …”
