ENV-548 / 4 credits

Teacher: Skaloud Jan

Language: English

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.

Content

Lectures

  • Concept and principles.
  • Inertial and other reference frames.
  • Gyroscope and accelerometer technology.
  • Attitude parameterization and modeling.
  • Strapdown mechanization.
  • Initial alignment.
  • Random processes and noise models.
  • Bayes and Kalman Filters.
  • External aiding
    INS/GNSS integration and reliability.
