Bergische Universität Wuppertal

Goals to be achieved

The University of Wuppertal works within the TRIPLE-FRS project on the design of a forefield reconnaissance system for the melting probe. The main task of the University of Wuppertal thereby is, to design and build an in situ probe that measures the permittivity of the ice surrounding the melting probe. These measurements will allow to account for respective refraction effects of the radio waves in ice. The data will additionally provide information on the ice properties, which can be used for scientific studies.

Tasks within the project

  • Simulation of near field permittivity effects 
  • Design of permittivity probe
  • Implementation of permittivity probe
  • Tests of permittivity probe in glacial ice
  • Production and measurement of different ices in lab
  • Model of ice layers on Europa 

Preliminary work (with one graph or one picture)

The University of Wuppertal already worked on different approaches of navigation in ice, and tested them within several field tests on alpine glaciers.  A system to measure the permittivity of ice via far field measurements was also already designed and additionally a method for near field permittivity measurements was tested. Based on those experiences, the in situ near field permittivity sensor will be developed. 

Substantial work was also done on simulations and models of Enceladus as an example for an icy moon of the outer Solar System (s. fig below).

Implementation steps

  • Electromagnetical modulation of measurement environment
  • Conceptional design of the permittivity probe
  • Development of the measurement concept setup 
  • Integration of the permittivity sensor
  • Tests and measurements with the device
