- In this papel, we analyzed the navigation error of TERCOM (TErrain COntollr Marching), which is TRN (Terrain
Referenced Navigation) batch processing, caused by scale factor error of radar altimeter and proved the possibility of false
position fix when we use thε TERCOM’s feature matching algorithm, Based on these, we proposed the new TRN batch processing algorithm using the slope measurements of terrain. The proposed technique measures on periodic changes in the
slope of the terrain elevation profile, and these measurements are used in the feature matching algorithm. By using the slope of
terrain data, the impact of scale factor errors can be compensated. By simulation, we verified improved outcome using this
approach compared to the result using the conventional method.
