Satellite Geodesy and Geodetic Modelling

Satellitengeodäsie und geodätische Modellierung

The use of quantum technology and measurement methods is expected to add great value to gravimetric Earth observation. The department Satellite Geodesy and Geodetic Modelling investigates essential application scenarios for novel quantum sensors as well as new measurement methods, also in combination with classical methods.

The spectrum of work ranges from determining the Earth's mass transport as a result of climate change and geophysical processes, and the determination of gravitational fields on planets and moons of the solar system.

The focus of the work is on

  • Development of concepts for gravimetric Earth observation using quantum sensors such as accelerometers and gradiometers
  • Analysis of spatial and temporal variations of the Earth's gravitational field in the context of future gravity satellite missions
  • Transfer of earth observation methods methods to other bodies in the solar system in the context of strategies for planetary exploration, e.g. the internal structure or search for water deposits
  • Integration of high-precision clocks and quantum inertial sensors in the solution of navigation tasks in the user segment
  • Further development of the processing of distance measurements to the moon by new and classical methods
  • Determination of parameters in the Earth-Moon system
  • Realisation and improvement of geodetic reference systems based on geometric observations and networks of clocks, e.g. on the moon and satellites
