Resource Overview
Detailed Documentation
This documentation describes a MATLAB program implementing GPS/INS integrated navigation with algorithm development based on a tightly coupled architecture. While specific implementation details aren't elaborated, the program's core objective involves enhancing navigation accuracy and robustness through optimal fusion of GPS measurements (position/velocity) and INS data (acceleration/angular rates). The algorithm likely employs Kalman filtering techniques for sensor fusion, potentially using extended or unscented Kalman filters to handle nonlinear systems. The tightly coupled approach suggests direct processing of raw GPS pseudorange and Doppler measurements rather than relying on pre-computed GPS solutions. Simulation results confirm the algorithm's effectiveness, though real-world performance validation requires additional experimental testing to account for environmental factors, sensor noise characteristics, and practical implementation challenges.
