AG1819 GPS and Image Based Surveying 6.0 credits
Global navigationsatellite systems have become a commontool not onlyfor navigationbut alsofor the collection ofdetailed geographicaldata, i.e. for applicationswherecm ormmaccuracy is required.Topographic surveyingor establishment ofgeodetic control networks are examples of such applications.The aimof the course isto gaintheoreticalandpractical knowledge onthe GNSS(Global Navigation SatelliteSystems), which isnecessary toplan, implementandprocessGNSS observations.The course providesknowledgeand skillsin terrestrial photogrametryandits use for collection of detailedgeographicdata.
Content and learning outcomes
Course contents
- Basic principles of positioning by means of satellites
- Components in satellite positioning systems and their function: satellites, control stations, receivers
- GNSS positioning and surveying methods, error sources and their elimination
- Detail surveying and setting-out with GNSS
- Image-based topographic measurement
- Combination of terrestrial and GNSS measurements
- Transformations: connection of GNSS measurements to local reference systems
Intended learning outcomes
After the course, the students should be able to:
- Identify which satellite observations can be used for positioning and explain how they can be used for calculation of position and speed of a receiver
- Identify components of GNSS and explain their function
- Plan, carry out and process GNSS observations by means of advanced geodetic receivers in order to establish geodetic networks, perform detail surveying and setting-out and to determine trajectory of a vehicle
- Evaluate quality of coordinates determined by GNSS observations
- Transform the coordinates into given reference system
- Explain principles of image-based topographic measurement
- Combine GNSS and terrestrial observations

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
Examination
- LAB1 - Laboratory work, 3.5 credits, grading scale: P, F
- TEN1 - Examination, 2.5 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
- written examination, TEN1, 2.5 credits, AF
- approved laboratory reports, LAB1, 3.5 credits, the PF
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
Examiner
Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
