FAG5127 Satellite Gravimetry 7.5 credits

The purpose of the course is the use of satellite gravimetry data in a broad range of geo-scientific applications. The main topics are:

• Satellites in orbit (orbits, forces, orbit determination, error sources),
• Gravimetry (satellite gravimetry and gradiometry concepts, orbit analysis, Earth's gravity field, current missions),
• Altimetry (radar and laser altimetry, past and current missions, working with altimetry data)
• Satellite gravimetry applications (Solid Earth, oceans, ice/sea ice, hydrology; gravity, geoid, datum unification, magnetic field, surface monitoring and climate change).

This course concerns both the theory and application of observing the Earth's gravity fields from

space-borne platforms. After the course the student is expected to be able to:

• explain the observation procedures including orbital mechanics,
• illustrate satellite gravimetry data signal propagation, errors and uncertainties,
• describe concepts of current satellite missions such as radar and laser altimetry, space gravimetry and gradiometry,
• use satellite gravimetry data for studying tectonics, geodynamics, ocean and ice surface monitoring, hydrology, and terrain modeling.

If the course is discontinued, students may request to be examined during the following two academic years.

• PRO1 - Project, 5.0 credits, grading scale: P, F
• SEM1 - Seminar, 2.5 credits, grading scale: P, 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.
