Limitations of Existing Navigation Approaches

VIO, SLAM, and GNSS each solve important parts of the navigation problem. None, however, independently provide continuous globally referenced navigation in GNSS-denied environments.

Comparison of VIO, SLAM, GPS/GNSS, and the ChaserAI Navigation Platform (VIN)
VIO Visual-Inertial Odometry	Excellent local motion estimation. Drift accumulates over time and distance. Does not provide persistent global position.
SLAM Simultaneous Localization and Mapping	Builds a consistent local map. Optimized for local autonomy. Does not inherently maintain a globally referenced state.
GPS GNSS	Provides global positioning. Vulnerable to jamming, spoofing and denial. Depends on external infrastructure.
VIN ChaserAI Navigation Platform	Powered by ChaserAI's Vision-Inertial Navigation (VIN) engine. Continuous globally referenced navigation. Onboard processing. Independent of GNSS. Independent of navigation communications. Designed for mission continuity in GNSS-denied environments.
