Colijn, Rogier (author)
With the maturization of the cubesat market, the requirements for finer control over satellite attitude drives the development of higher performance Attitude Determination and Control Systems. (ADCS)<br/><br/>The ADCS uses reaction wheels as an actuation method, which in turn use brushless DC (BLDC) motors to rotate a heavy rotor wheel. BLDC...

Aerosol is defined as the suspension of solid or liquid in the atmosphere. While some aerosols do not pose any serious threat to humankind, others have devastating effects. Thus, it is important to understand the type and distribution of these aerosols in the atmosphere. While traditional satellite data pose delays due to the huge amount of data...

Satellite tracking is used to predict a satellite’s orbit to communicate and perform other key functions. It is commonly performed using large ground-based radars with an accuracy of 1 to 10 km or specialized onboard satellite systems. Ground optical systems are a proliferating technology for satellite tracking, identification, and...

Stereo matching, the process of inferring depth maps from stereo images, is one of the most heavily investigated topics in computer vision. It is part of the first module of navigation systems of planetary rovers, e.g., NASA’s Mars Exploration Rover (MER) missions, NASA’s Mars Science Laboratory (MSL) mission, and ESA’s ExoMars mission. Many...

Low downlink data rates limit the scientific and commercial return from small satellites. Now with constellations of small satellites becoming popular, the amount of data generated in low Earth orbit will be greater than ever. A novel data downlink architecture for small satellites is investigated that uses non-geostationary orbit (mega-...

The Lunar Zebro is a small six-legged robot. It has the potential to be used in a swarm carrying out objectives like exploring planetary surfaces. A new step towards autonomous navigation is made with the newly developed Obstacle Processing ALgorithm (OPAL) using primarily open-source libraries. This study showed that the initial iteration of...

In 2024, a rover will leave Earth on a daring mission to explore Phobos, one of the two moons of Mars. Phobos has a severe thermal environment, with surface temperatures ranging from -153 °C to +57 °C and an 8-hour diurnal cycle. This work focuses on validating the performance of the locomotion system of the Mars Moon eXploration (MMX) rover....

For any space mission, the communication subsystem is an indispensable part of the satellite that carries the payload. Traditionally, on-board antennas transmitting Radio Frequency (RF) waves to the receiver have been used. Nowadays, laser communications is becoming increasingly popular due to its potential to become a license-free, secure and...

What is the most advantageous magnetic attitude control torquer for reducing angular rates of a PocketQube? To answer this question several magnetorquer concepts are explored and two concepts are built. In addition, a method to test these magnetorquers is developed. An Air-core magnetorquer system and a magnetorquer embedded in a PCB are...

This master thesis addresses the need for a telemetry processing for Delfi Space spacecraft operations, a nano-satellite program of the Delft University of Technology. It lays the groundwork for the telemetry processing system (TPS) implementation and explores the design guidelines for a highly scalable but robust and adaptive architecture.
