Small satellite systems such as CubeSats and PocketQubes have strict requirements in terms of size, weight, and power available onboard. In light of these constraints, small satellite systems typically omit the inclusion of a ranging system due to its power and specialized hardware requirements. However, new research in satellite ranging...

Multiple in-space experiments with deep learning have shown promising results in applying deep neural networks for automation of satellite fault detection tasks. However, the deployment of such neural networks on small satellites with low-power onboard computers is hindered by the highly limited computational resources of these devices. In this...

CubeSats have risen in popularity since its first launch in the year 2003. The low mass, lower launch cost, lower development cost, possibility for piggyback with larger satellites and lower development time involved compared to larger satellites have opened them to be commercialised by private companies. In contrast to being used for...

Autonomous orbit determination could help reducing the growing load on ground-based deep space networks. For small satellites, orbit determination based solely on inter-satellite measurements could be a strong alternative for conventional ground-based navigation support. The possibilities of this autonomous orbit determination method are...

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...
