State Estimator using Hybrid Kalman and Particle Filter for Indoor UAV Navigation

2021

Master's thesis in Mechatronics (MAS500) Unmanned aerial vehicles (UAVs) are being used for outdoors inspection and surveying tasks. When operating in an outdoor environment, the global navigation satellite system (GNSS) is predominantly used for position aiding, and magnetometers are used for heading aiding. In combination with an inertial sensor, these sensors form the backbone for state estimation for drones operating in an outdoor environment. A desire to utilize UAVs for inspections in indoor environments means that new challenges are faced. One of these challenges is that the traditional GNSS is unavailable for position aiding, and magnetometers can be unreliable in the presence of in…
