Navigation

LEARNING OUTCOMES

The aim of this course is to teach the fundamental principles of navigation. Emphasis is given in surveying applications like hydrography, vehicle guidance, airborne data collection etc. Upon successful completion of the course the students will be able to:

• understand the basic principles of navigation
• choose the appropriate method and equipment for carrying out a navigational task
• process kinematic observations for determining trajectories
• plan and execute basic hydrographic works

 

General Competences

• Search for, analysis and synthesis of data and information, with the use of the necessary technology
• Adapting to new situations
• Working independently
• Team work
• Production of new research ideas

 

SYLLABUS

Theoretical part:

1. Historic review of navigation techniques
2. Basic principles of navigation (Line of Position, dead reckoning, position fixing, accuracy measures in navigation)
3. Celestial navigation
4. Nautical chart & compass
5. Terrestrial radio navigation: angular, ranging, hyperbolic systems (Loran-C, OMEGA)
6. Satellite Navigation (GPS, GLONASS, GALILEO, BEIDOU)
7. Satellite based augmentation systems (EGNOS and WAAS).
8. Accelerometers (mechanical, MEMS)
9. Gyroscopes (mechanical, LRG, FOG, MEMS, gyro compass)
10. Inertial navigation systems (gimbalded, strapdown, drift, alignment)
11. Applications of Kalman filter in navigation
12. Indoor navigation
13. Drone navigation
14. INS/GPS integration
15. Hybrid systems

 

Laboratory part:

1. Field measurements with GPS and GNSS receivers for navigational applications (autonomous positioning, EGNOS, DGPS)
2. Processing of kinematic observation for the determination of trajectory and state vector
3. Interfacing GNSS receivers and processing unit using NMEA protocol
4. Estimation of radio data link range
5. Processing of accelerometer data.

 

STUDENT PERFORMANCE EVALUATION

Assessment language: Greek (English for ERASMUS students upon request)
Performance evaluation method:
• Final Written Exam (70% of the final grade) of graded difficulty, which include short-answer questions, open- ended questions and solving simple problems.
• Evaluation of laboratory project (30% of the final grade) which includes exercises.

The evaluation criteria have been presented to the students before the final examination. Students can see their evaluation upon request and receive clarifications on their grades.
