Rendezvous in orbit has recently regained considerable attention, as it is required to enable on-orbit servicing or active debris removal activities. The pressing need for the realization of suchmissions falls within the more general societal attempt to make human activities more sustainable, avoiding wasting valuable resources and ensuring that...

Chaves Jimenez, A. (author)
Spacecraft orbit and attitude dynamics have been classically seen as two separated<br/>subjects, since the effect of attitude in orbit dynamics was deemed too small to be<br/>considered, or simply, modeled as noise in the estimation process for most satellites.<br/>In the eighties, a study by [1] showed that for a very large spacecraft,...

With the rising demands from customers and users and the development of ever advanced technologies, many space missions nowadays require more than one satellite to fulfill their mission objectives. Although replacing single satellite systems (SSSs) by multiple satellite systems (MSSs) offers advantages, such as enhanced spatial and temporal...

The repertoire of words in the English language to refer to groups of animals is quite fascinating to say the least – a congregation of alligators, an army of ants, a troop of baboons, a pride of lions, a train of camels, a destruction of cats, an intrusion of cockroaches, a mob of emus, a plague of insects, a drift of pigs, and so on. The...

In recent years, there has been an increase in the number of small multi-mission platforms such as CubeSats, in an attempt to reduce costs of space missions. CubeSats have been used for different purposes including Earth observation, research and technology demonstration.<br/>However, a key technology that is still under development is the...

The aerospace industry is recently experiencing growing interest in very small spacecraft like nano- and pico-satellites. However, these very small satellites are still being developed in most cases without a dedicated propulsion system limiting their capabilities. The micro-resistojet has been recognized as a suitable propulsion system for...

Space debris poses a big threat to operational satellites which form a crucial infrastructure for society. According to the main source of information on space debris, the U.S. Space SurveillanceNetwork (SSN), more than 17 500 objects larger than 10 cmhave been catalogued as of February 2017. Among the total number of objects in orbit, only 1875...

Satellite swarms are a novelty, yet promise to deliver unprecedented robustness and data-collection efficiency. They are so new in fact that even the definition of what a satellite swarm is is disputable, and consequently, the term "swarm" is used for practically any type of distributed space architecture. This thesis poses the proposed...

This dissertation focuses on intra-spacecraft wireless communication as a solution for reducing the spacecraft onboard harness. Despite outstanding advances in aerospace industry, the cost of accessing space is still very high and the amount of engineering work required for spacecraft design and development is enormous. The key elements which...

Fractionated spacecraft deploy satellites' functionalities, such as computation, communication, data storage, payload operations and even power generation, onboard several modules that share those functionalities through a wireless network. With the advent of such an innovative space architecture, non-traditional attributes such as flexibility,...

Maessen, D.C. (author)
The thesis deals with the relative navigation between two small formation flying spacecraft. The inter-satellite distance is measured using locally generated radiofrequency ranging signals. Design considerations for the spacecraft and the relative navigation system are discussed as well as the estimation of the relative state. The influence of...

The European Proximity Operation Simulator (EPOS) is a hardware-in-the-loop (HIL) system aiming, among other objectives, at emulating on-orbit docking of spacecraft for verification and validation of the docking phase. This HIL docking simulator set-up essentially consists of docking interfaces, simulating the servicing satellite called chaser...

The trend of space technology developments is moving from high power consuming, bulky and costly systems towards low-power, small, low-cost and flexible systems. Thus, the spacecraft can benefit from multi-purpose and flexible systems which can be low-power and low-cost by employing new technology. One example of such system is a GNSS receiver...

Mass-spring and liquid dampers enable structural vibration control to attenuate single, coupled lateral and torsional vibrations in diverse structures. Out of these, the passively tuned liquid damper (TLD) class is wanted due to its broad applicability, extreme reliability, robustness, long life time and ease of manufacturability. In this PhD...

Space tethers are cables that connect satellites or other endmasses in orbit. The emptiness of space and the near-weightlessness there make it possible to deploy very long and thin tethers. By exploiting basic principles of physics, tethers can provide propellantless propulsion and enable unique applications such as the provision of comfortable...

Formation flying is commonly identified as the collective usage of two or more cooperative spacecraft to exercise the function of a single monolithic virtual instrument. The distribution of tasks and payloads among fleets of coordinated smaller satellites offers the possibility to overcome the classical limitations of traditional single...
