There is a growing demand for nano-satellite missions that require advancements in micro-propulsion capabilities to facilitate a wider range of orbital maneuvers. Among these capabilities, the ability to accurately control thrust would unlock new possibilities for nano-satellite applications, including missions such as space debris removal and...

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...

ADCS magnetometers on board of satellites suffer from the disruptive magnetic field produced by the satellite itself. For CubeSats and PocketQubes this magnetic field is usually not quantified. If the largest magnetic field sources are known and if there is freedom in the magnetometer placement, the magnetometer is simply placed as far from the...

Reaction wheels are often the main contributor to microvibrations on satellites. These vibrations are a source of pointing errors and therefore need to be limited as much as possible. The miniaturization trend in the space industry and universities fostered the production of very small reaction wheels, suited to Cubesat and PocketQube scales. A...

This thesis provides an innovative architecture for CubeSats and PocketQubes to improve their performance and reliability. CubeSats and PocketQubes are standard satellite form factors composed of one or more cubic units of 10 cm and 5 cm respectively. It is found that the current modular subsystem approach and the electrical interfaces are not...

A Low-Pressure Micro-resistojet (LPM) is a type of in-space electrothermal propulsion system for satellites that works by heating low-pressure (50 to 300 Pa) fluid flowing through microchannels/slots (typically <1 mm diameter) using resistive heating elements like thin-film Molybdenum. This thesis delineates a response surface based method to...

The advent of miniaturized satellites has sparked an interest in effective methods of exploiting their capabilities. Potential has been found in propulsion­enabled units, and TU Delft is at the forefront of researching and developing suitable propulsion modules for thrust generation or attitude control of small satellites classified as Cubesats...

PocketQubes are a form factor of highly miniaturized satellites with a body of one or more cubic units of 5 cm. In this paper, the characteristics of PocketQubes in terms of their constraints and their (potential) utility are treated. To avoid space debris and limit collision risk, the orbits of PocketQubes need to be constraint. An analysis...

AE faculty at TU Delft is currently developing a PocketQube satellite under the name of Delfi-PQ. Following the previous study, performed on a high level systems engineering on Delfi-PQ propulsion sub-system, there is a need to verify the propulsion sub-system's design, its final operational envelope values, and propulsion sub-system's...

The PocketQube is an emerging satellite class, which pushes the miniaturization of space technology beyond the well-established CubeSats, promising rapid design-to-orbit cycles while lowering the cost of accessing space. A showstopper in the success story of nano- and picosatellites are their high mission failure rates. Environmental testing...

This paper presents the design of a multi-frequency deployable antenna system for femto-satellites as part of the Delfi-PQ project, a PocketQube with a size of 50x50x178 mm which is being developed by the Delft University of Technology. This new form factor brings its own challenges on every subsystem and it is seen as a stepping stone towards...

PocketQubes represent a new type of cube-shaped platforms with dimensions of 50x50 mm and mass of 250 g. Just like the CubeSats, these platforms are also split in units which are referred to as 1P. The Delft University of Technology has been working on Delfi-PQ, a 3P PocketQube with the dimensions of 50x50x178 mm. This miniaturized size brings...

CubeSats have been extensively used in the past decade as scientific tools, technology demonstrators and for education. Recently, PocketQubes have emerged as an interesting and even smaller alternative to CubeSats. However, both satellite types often lack some key capabilities, such as micropropulsion, in order to further extend the range of...

Developers experience issues with the compatibility, connector size and robustness of electrical interface standards for CubeSats and PocketQubes. There is a need for a lean and robust electrical interface standard for these classes of satellites. The proposed interface standard comprises a linear data bus which is used for housekeeping data,...

The dominant architectural approach in CubeSats and PocketQubes is the use of modular physical units, each hosting (part of the) components of classical (virtual) subsystems. Many of these small satellites, however, also host subsystems or experiments with slightly alternative approach, e.g. with cellularization of components or the integration...

A highly miniaturised reaction wheel was developed for Delft University of Technology’s PocketQube (PQ) mission as topic of this thesis project. Delfi-PQ, a picosatellite, aims to demonstrate a reliable core bus platform for PocketQubes with a form factor of 5x5x5 [cm] and one or more payload(s). PocketQubes hold the potential to reduce the cost...

The definition of the CubeSat is already nearly two decades old. This results in the trend that a large fraction of CubeSat missions are leaving the domain of (educational) technology demonstration and entering that of commercial applications. Therefore a larger focus is put on the reliability and compatibility of commercial of the shelf systems...
