Falckenheiner Soria, Sebastian (author)
Synthetic Aperture Radars (SAR) have demonstrated to be great instruments for space-based Earth observation in the microwave frequency. Metasurface antennas, on the other side, are a new type of planar antennas with a great potential for space applications, as they are compact and easy to produce. Several methods have been developed in the past...

Further development of the Delft Deployable Space Telescope (DST) was needed to solve for defocus due to thermal expansion. This thesis focuses on implementation of stray light design methodology on the deployable baffle to provide a more stable temperature environment. This methodology utilises various baffle shapes and the arrangement of vanes...

To mitigate the growth of space debris, it is vital that Active Debris Removal (ADR) is performed in the near future. Since ADR will require robust relative navigation, future spacecraft should be marked with fiducial markers that are robustly extracted from an image taken by a chaser spacecraft. To prevent the restriction of robotic movement...

The need for higher spatio-temporal resolution Earth observation increases rapidly. To fill this need, the Deployable Space Telescope (DST) project aims to make a light-weight, low-volume deployable telescope. In doing so, the achievable ground resolution is high while the cost per telescope stays low. This allows for the DST to be used in...

Ceccotti, Tiberiu (author)
Electromagnetic metasurfaces in recent years have drawn significant attention in the Optics community due to their novel optical properties and miniaturized integration advantages. Since the optical properties of those materials are complex to model and require finer theory than what implied in geometrical optics, systematic integration study of...

The Deployable Space Telescope (DST) project aims at producing a competitive telescope by using segmented deployable light weighted optics which reduces launch volume and mass, and thus launch costs. Due to the criticality of heat management to the performance of the telescope, a thermal model had to be built in order to determine the expected...

As part of the New Earths in the Alpha Cen Region (NEAR) experiment, VISIR, an imager and spectrometer for the mid-infrared at the Very Large Telescope (VLT) of the European Southern Observatory, will be soon upgraded to improve its performance in terms of high contrast and sensitivity for the detection of Earth-like planets in the Alpha...

The thesis discusses the design of the secondary mirror support structure for the deployable space telescope. In the thesis the entire support system is considered, including system layout and mirror interface. A selection of hinge concepts were identified and final concepts were selected in trade-offs. The mid hinge was selected to be an...

Corvers, Matthew (author)
In this thesis, the development of a deployment mechanism for a primary mirror of a space telescope is discussed. A mistake has been found in the earlier work on the design of this subsystem, due to which the design is set back to a concept selection phase. A trade-off has been made between several concepts. A simplified thermal model that...

Launch costs for high-resolution space telescopes for Earth observation can be reduced when the telescope mirrors are made deployable. However, such a system is subject to optical aberrations that decreases image quality. To counter these aberrations, an Aberration Correction System (ACS) is proposed that uses a deformable mirror (DM) which is...

This thesis describes the entire process from the definition of customer requirements to the verification and validation of requirements concerning a breadboard model of an Inflatable Radiator (INFRA). INFRA is designed to provide high thermal performance to mass ratio radiator to accommodate increasing payload heat dissipation demands of future...

As technology improves, increasingly higher resolution payload can be achieved using Cubesats for Earth observation. The diffraction limit prevents the resolution to up to a few meters for these missions and are confined to Very Low Earth Orbits (VLEO). At these altitudes, strong disturbances act on the system, limiting its lifetime and the...

Nowadays space missions rely heavily on optical payloads to carry out a wide range of tasks including earth observation, weather monitoring, astrophysics research and communications. Until recently, the design of such systems was done according to design principles such as rotational symmetry as it simplifies the theory, reduces technological...

DIMITRI is a tool that has been developed for monitoring the radiometric performance of optical instruments onboard Earth observation satellites. It includes a reflectance model through which a calibration coefficient is computed which is used for performance monitoring. In this thesis, the uncertainty that is associated with this coefficient is...

An interesting concept related to photovoltaic energy is Concentrated Photovoltaics (CPV), in which sunlight is focussed on a PV cell through lenses and mirrors, thereby increasing the incident irradiance on the PV cell. Solar concentration is proven to not only increase the output power of PV cells, but also to increase the electrical...

The use of deployable structures for space telescopes has the advantage of enabling options to improve their optical performance and reducing the launch volume. The Deployable Space Telescope (DST), which is currently developed by the Space Systems Engineering (SSE) department, will make use of a high precision deployable structure to extend the...

Applications for space telescopes require ever higher resolutions. This is driving space telescopes to keep getting bigger as they need a large primary mirror to achieve these resolutions. Such large instruments are also heavy and cost a lot of money to launch. Current launchers offer a limited amount of space making it impossible to launch a...
