Simulations and Modelling (Dynamics) Intern

Introduction

At Atomionics, we build quantum gravimeters that are set to revolutionize the resource exploration industry. We are looking for a motivated intern to contribute in simulating a moving-base quantum gravimeter.

Responsibilities

1.Develop and improve software implementation of a simulation model for the output of a quantum gravimeter undergoing 6 axis motion.

2.Determine forces and accelerations experienced by the quantum gravimeter and compare them to those measured by an IMU. Modelling forces and rigid body dynamics:

• Forces in Inertial and Non inertial coordinate frames
• Modelling accelerations due to Rotation and lever arms
• Kinematics in 3D space

3.Data Processing and Analysis of Signal Characteristics: FFTs, PSDs, Allan deviations.

• Finding optimal filters
• Error propagation

4.Support the integration of transfer functions into motion libraries to build sensor fusion algorithms.

5.Analyse differences between the simulation and the experimental data in a set of conditions.

Qualifications

• Engineer or physicist with a background in computer science, sensor fusion, signal processing, or related fields
• Experienced with modelling of classical mechanics: inertial and non-intertial reference frames, rotating reference frames, Centrifugal and Coriolis accelerations, lever arms
• Familiarity with Python: NumPy, SciPy, pandas, visualization packages
• Analytically minded and skilled in Root Cause Analysis
• Interested in deep technical problem statements and capable of picking things up

Preferable if you have:

• Familiarity with sensor fusion fundamentals: Euler angles, quaternions, integration, dead reckoning
• Familiarity with foundation of signal analysis such as FFTs, noise analysis
• Experienced with motion and localization packages such as Gazebo
• Familiarity with modelling in Matlab and simulations
• Experience with interfacing an IMU and collecting experimental data
• Familiarity with IMU characteristics: sampling rate, noise, bias drift, etc.
