CUSTARD (Cranfield University Space Technology Advanced Research Demonstrator) - A Micro-System Technology Demonstrator Nanosatellite. Summary of the Group Design Project MSc in Astronautics and Space Engineering. 1999-2000, Cranfield University

CUSTARD (Cranfield University Space Technology And Research Demonstrator) was the group design project for students of the MSc in Astronautics and Space Engineering for the Academic Year 1999/2000 at Cranfield University. The project involved the initial design of a nanosatellite to be used as a technology demonstrator for microsystem technology (MST) in space. The students worked together as one group (organised into several subgroups, e.g. system, mechanical), with each student responsible for a set of work packages. The nanosatellite designed had a mass of 4 kg, lifetime of 3 months in low Earth orbit, coarse 3-axis attitude control (no orbit control), and was capable of carrying up to 1 kg of payload. The electrical power available was 18 W (peak). Assuming a single X-band ground station at RAL (UK), a data rate of up to 1 M bit s-1 for about 3000 s per day is possible. The payloads proposed are a microgravity laboratory and a formation flying experiment. The report summarises the results of the project and includes executive summaries from all team members. Further information and summaries of the full reports are available from the College of Aeronautics, Cranfield University

Judicial Discipline and Due Process in Washington State—In re Deming, 108 Wash. 2d 82, 736 P.2d 639 (1987)

This Note evaluates recent developments in Washington State concerning due process rights in judicial disciplinary proceedings. The focus is on In re Deming, a recent disciplinary case decided by the Washington Supreme Court. The analysis by the court in Deming highlights the conflict between the desire to discipline wayward judges and the need to protect the autonomy of the judiciary. The historical and procedural background of the Deming case is discussed first, and then three important procedural issues raised in the opinion are analyzed. The Note concludes that, although the court\u27s broad due process holdings lack foundation, its specific procedural requirements are justified

Debris removal from low earth orbit (DR LEO)

Students of the MSc course in Astronautics and Space Engineering 2009/10 at Cranfield University studied a low Earth orbit (LEO) debris removal mission for their group project. The mission's name was DR LEO (Debris Removal from LEO) and its aim was to develop a credible mission baseline using conventional technology to perform active debris removal from LEO. This report summarises the students' work and their findings. The report consists of an overview and discussion of the technical work of the project and a compilation of the executive summaries which describe the specific contributions of each student. The baseline mission design developed is broadly credible and provides a useful benchmark against which other missions can be compared to evaluate the potential of alternative technologies. The mission costing from this first design iteration sets a benchmark cost per unit mass de-orbited of approximately € 20-30k kg - 1 using conventional chemical propulsion

GeoSAR Feasibility Study: Summary of the Group Design Project. MSc in Astronautics and Space Engineering 2012/13

Students of the MSc course in Astronautics and Space Engineering 2012–13 at Cranfield University performed a feasibility study of a geosynchronous radar mission for their group project. This report summarises the students’ work and their findings. The report consists of an overview and discussion of the technical work of the project and a compilation of the executive summaries which describe the specific contributions of each student. The mission studied is a Ku-band monostatic SAR in a small inclination (80 km relative orbit diameter) geosynchronous orbit. The total launch mass is 2 tonnes, and images with resolution 40 m to monitor land subsidence in urban areas are produced. The mission appears to be feasible within the scope of an ESA Earth Explorer proposal

If you are the author please contact PEARL Admin ([email protected]) to discuss options.The demands off managing in an international operating environment has changed considerably over the past 20 years due to developments in global markets. Multinational enterprises face fierce international competition and are now tasked not only with developing effective competitive capabilities but also with maximising the knowledge and expertise developed in one part of the organisation by transferring it to another. This work has investigated the position of multinational enterprises in the developing global market and through a broad and thorough review of current literature, identified a gap in the knowledge -a tool for helping the assessment of the transfer of technology prior to the transfer process taking place. Using existing models as a foundation, a new framework has been developed with observations from three case study organisations and the incorporation of other relevant literature. To -make use of the new framework to practitioners it leas been used as the basis of a workbook by which the anticipated difficulties can be judged and a priority focus developed. Validation of the `r ework has been carried out by a panel of industrialists and academics experienced in international technology transfer. The thesis concludes with a series of recommendations for further work. The originality of this work lies in the development by the author of the new pre-transfer assessment Framework. This should provide clear advantages over previous approaches and give way to improving the success of technology transfer projects

A Quantitative study of kite performance in natural wind with application to kite anemometry

Although kites have been around for hundreds of years and put to many uses, there has so far been no systematic study of their performance. This research attempts to fill this need, and considers particularly the performance of kite anemometers. An instrumented kite tether was designed and built to study kite performance. It measures line tension, inclination and azimuth at the ground, :sampling each variable at 5 or 10 Hz. The results are transmitted as a digital code and stored by microcomputer. Accurate anemometers are used simultaneously to measure the wind local to the kite, and the results are stored parallel with the tether data. As a necessary background to the experiments and analysis, existing kite information is collated, and simple models of the kite system are presented, along with a more detailed study of the kiteline and its influence on the kite system. A representative selection of single line kites has been flown from the tether in a variety of wind conditions. The results from these experiments are analysed to obtain general performance measurements for these kites in real, turbulent, winds. The analysis is taken a stage further to evaluate the kites for anemometry, and to study the dynamics of the kite system. The most suitable kites for anemometry are identified, together with the wind conditions in which they may be used and the wind information available from measurements at the tether. The study ends with a review, and a discussion of useful areas of further work. [This digital (pdf ) version of the thesis was created in August 2005. The content is identical to that of the original paper copy of 1986, although the layout and pagination differs in detail. Readers should note that anemometer calibrations described in Hobbs (1994) suggest that the windspeed values given in this thesis are incorrect by a few percent: however, the general conclusions about kite performance stated in the thesis are unaffected by these changes.

Laplace plane GeoSAR feasibility study: summary of the group design project MSc in astronautics and space engineering 2014-15, Cranfield University

Students of the MSc course in Astronautics and Space Engineering 2014-15 at Cranfield University performed a feasibility study of a geosynchronous radar mission for their group project. This report summarises the students' work and their findings. The report consists of an overview and discussion of the technical work of the project and a compilation of the executive summaries which describe the special contributions of each student. The mission studied is a geosynchronous synthetic aperture radar Earth observation mission using the Laplace orbit plane to reduce station-keeping propulsion demand. User applications are drawn from a wide range of sectors (agriculture, meteorology, geohazards, etc.) and are translated into system design requirements. The proposed mission design uses satellites with 13 m diameter antennas and a total electrical power demand of 6 kW. The mission seems feasible, although further study is recommended especially for the areas of _ orbit selection with respect to user requirements, imaging performance and orbit maintenance, _ mass budget (driven largely by the propulsion system), _ user requirements, imaging performance and operational imaging modes, _ opportunities for improved imaging with a constellation

Method for estimating clutter limited geosynchronous synthetic aperture radar performance

This paper reviews the geosynchronous synthetic aperture radar (GeoSAR) literature and highlights a gap in land clutter theory.The gap concerns clutter models with weather dependence for incidence angles between 20 and 70 degrees. We update with an improved clutter model the system performance method presented at IGARSS 2016 to estimate the SAR system performance taking into account the weather statistics and the landcover of the target area. The performance statistics obtained with this method allow to estimate the fraction of time (e.g. percentage of a month) in which the SAR system can accomplish the user’s requirement. So far the method has been developed for short vegetation (specifically wheat), as source of clutter, and for bare land and urban area as other target areas. A full clutter model is still under development, but results are presented for the weather dependence of the coherent fraction of the scattered power. Since the azimuth spread of clutter power for GeoSAR can exceed the beam footprint in strong weathe rconditions, we expect improved image quality in these conditions. Two example of the effect of different clutter power probability density function are briefly presente
