A navigation and positioning system for an underwater glider includes a micro-electro-mechanical system inertial measurement unit, a global positioning system receiving module, a triaxial magnetometer, a Doppler velocimeter, and an integrated navigation hardware processing system. If a navigation and positioning error is too large, the underwater glider stops working in real time and switches from the underwater working state to the up floating error correction state; and when velocity and location errors of a GPS/INS integrated navigation system are smaller than specified thresholds, the underwater glider switches from the up floating error correction state to the underwater working state and continues to work. An Hoc Kalman filter algorithm based on an adaptive multiple fading factor is established to ensure robustness and adaptability of navigation and positioning of a glider.
