DTU Space seeks applications for a two years postdoc position at the institutes geomagnetism Group with a starting date between August 15th and November 1st 2018
 
Focus is on UAV-borne magnetic data acquisition, processing and interpretation.
 
Part of UAV-QMS (2017-2021) and MuVerDrone (2018-2021) projects is funded by Innovation Fund Denmark and EIT-RM, respectively.

The Geomagnetism Department at DTU Space currently leads the MuVerDrone and UAV-QMS projects with the purposes of developing efficient UAV-based platforms for geophysical surveying in relation mineral exploration and UXO detection. Our main focus is to implement magnetic sensor systems on various UAV platforms and to develop stae-of-the art processing software. Other sensor systems (Lidar, hyperspectral, etc.) are being tested in parallel.
 
A key UAV platform of both projects is the hybrid fixed-wing and VTOL Smart UAV by DTU Space and Sky-Watch A/S (see https://www.youtube.com/watch?v=No4zbFxnJFM). However, other multirotor (and potentially fixed-wing) platforms are being used as well.

Responsibilities and tasks
You will assist with the design and integration of magnetic (gradiometer) systems on UAV platforms. Your role will be to assist the aerospace engineer in constructing systems for optimal data acquisition by looking into the magnetic noise of the platforms etc. 
 

  • You will be in charge of processing magnetic (gradiometer) data from these platforms from field campaigns using “Geosoft Oasis Montaj” or your own software. You will use the results for iterative improvements of the magnetometer systems and the processing scheme. This includes methods for passive de-Gaussing of the aircraft(s) and/or removal of the stray magnetic signature during post-processing. Data from prove-of-concept field campaigns e.g. in Sweden will be used for geological interpretation.
  • Priority is given to the Smart UAV platform where (i) front-boom total-field and (ii) wingtip gradiometer systems are to tested. Second priority is given to magnetometer systems on other UAV platforms (e.g., large multirotor UAVs). Noise reduction is essential for all the magnetic solutions.  
  • On all the above tasks, you will be working closely together with an aerospace engineer who will be in charge of designing and building the magnetometer systems. You will also work closely together with a PhD student in charge of developing towed magnetometer systems and associated processing software.
  • If time and qualifications permits, you may be looking into data from other sensor systems such as Lidar or EM.
Qualifications
  • You must hold a PhD in geophysics, engineering or similar at the time of employment.
  • You must have a strong background in math, physics and programming (preferably Python). 
  • Hands-on experience with airborne magnetic (gradiometer) data acquisition and processing is essential. 
  • A fundamental technical and/or practical knowledge of UAVs is beneficial. Likewise, is a basic knowledge of GNSS-IMU systems. 
  • Other sensors than magnetometers may be relevant to our research. Priority is given to candidates with experience also in Lidar or EM systems.
  • Flexibility and self-motivation are desired skills at DTU. We expect you to take responsibility of your own work but at the same time to thrive on collaboration and teamwork. The success of your project depends to a high degree on collaboration with colleagues at DTU Space. Hence, you believe in dialogue and feedback as the best foundation for sound decision-making  
  • You are driven by pushing boundaries and are not afraid of taking the lead
