Comparison of TERCOM and DSMAC Localization Techniques.

Caption

The image illustrates two different localization techniques for UAV navigation in GPS-denied environments: TERCOM (Terrain Contour Matching) on the left, which uses pre-mapped terrain data for absolute localization, and DSMAC (Digital Scene Matching Area Correlation) on the right, which compares real-time terrain data to a stored database. While TERCOM is effective in areas with distinguishable features, DSMAC provides more flexibility, particularly in dynamic and featureless environments.
