About Us

The Intelligent Computational Geodesy and PNT (ICG-PNT) Lab develops advanced theories and algorithms for high-precision Positioning, Navigation, and Timing (PNT), rooted in a strong foundation of Global Navigation Satellite Systems (GNSS). Our research addresses the critical challenge of achieving reliable, high-accuracy positioning across diverse environments, spanning terrestrial and urban areas, satellite orbits, and deep space.

At the core of our lab is Intelligent Computational Geodesy, a methodological framework that integrates rigorous geodetic modeling with modern computational and data-driven techniques. We focus on key challenges such as integer ambiguity resolution (IAR), atmospheric error modeling, and high-dimensional parameter estimation, while incorporating artificial intelligence to enhance model adaptivity, robustness, and real-time performance.

This unified approach is applied consistently across the full spatial hierarchy, extending from ground and low-altitude platforms to LEO satellite systems, and further to lunar and deep-space navigation. Concurrently, it enables resilient and alternative PNT solutions in GNSS-challenged environments through multi-sensor fusion, integrity monitoring, and emerging quantum technologies.
