This thesis explores alternative positioning systems for environments where GPS is ineffective, such as indoors and underwater. It focuses on three main scenarios: indoor localization for first responders using a foot-mounted inertial magnetic sensor unit, maritime navigation using radar as a backup to GPS, and underwater positioning using a sensor network. The thesis presents methods to estimate heading indoors using a Kalman filter and gyro measurements, radar-based positioning for naval vessels, and positioning underwater sensors using magnetic disturbances caused by a friendly vessel. The goal is to improve safety and efficiency in scenarios where traditional GPS is unavailable.

This thesis explores the development of indoor localization systems using magnetic field-aided inertial navigation. It focuses on using spatial variations in indoor magnetic fields to provide accurate positioning information without the need for pre-installed infrastructure. The research addresses three core challenges: sensor calibration, creating a magnetic field model, and designing a state estimation algorithm. The proposed system integrates a planar magnetometer array with an inertial measurement unit to capture magnetic field variations and aid navigation. The system's effectiveness is demonstrated through simulations and real-world testing, showcasing reduced position drift and improved consistency. This work contributes to advancements in indoor localization technologies, particularly for autonomous systems and robotics.
