Enseignant: Skaloud Jan
Langue: Anglais
Withdrawal: It is not allowed to withdraw from this subject after the registration deadline.
Summary
Determination of spatial orientation (i.e. position, velocity, attitude) via integration of inertial sensors with satellite positioning. Prerequisite for many applications related to remote sensing, environmental monitoring, mobile mapping, robotics, space exploration, smart-phone navigation, etc.
