Research, Design and Manufacture of Functional Components of the Microsatellite's Components
Abstract
This paper deals with the main current results of investigation ,
designing and manufacturing of functional components of microsatellite,
obtained in the State investigation programm, "Valoristaion of renewable
energy in the Republic of Moldova and development of Moldavian
Satellite". The satellite will have a mass of 12.5 kg. The paper
contains 8 chapters, 11 figures, 11 bibliographical references.
... În primii doi ani (2010‐2012) au fost stabilite obiectivele misiunii satelitului, au fost elaborate și fabricate în prima variantă subsistemele de bord ale microsatelitului (MS) [8]. a) b) Pentru cercetarea experimentală a cinematicii și dinamicii MS, la UTM a fost elaborat și proiectat un simulator cu 3 grade de mobilitate (figura 15) pentru improvizarea mișcării aleatorii a MS în zbor pe orbită (cu mișcare sfero‐spațială cu un punct fix al suportului MS). ...

This book contemplates on the evolution of engineering sciences development in the Republic of Moldova in the postwar period. The author emphasizes the place and role of engineering sciences at different stages reflected in the decisions of the party (until 1990) and State powers, reveals chronologically the establishment of and support to the priorities regarding science development by directions and fields. Also, the author discloses the reasons for reticence in supporting engineering sciences in the first 15 years of the postwar period and highlights the factors which favored the rapid expansion of their development later.
By the way of material exposed in the paper, the author aims to annihilate the information vacuum imposed in the Soviet period on the engineering sciences achievements on topics considered tangible with the military complex, or as very important for the industrial and technological development of the country. Thus, the author tends to tackle the thesis, rooted in our society so far, that Moldovan economy has grown mainly as agricultural one and scarcely industrial. In fact if we analyse, for example, the State Budget – 1987 [8] we can see, for sure, that in the structure of revenues the share of industry prevails over those coming from agriculture and services together.
For the first time, the author presents a picture of the Moldovan engineering performance exemplified only by a few top achievements, obtained due to the intensity and prestige of cooperation between the scientific researchers and institutional structures empowered with research-innovation and directly dependent on the efficiency of mechanisms and instruments of research funding. The author makes reference to the complexity, high quality and importance of scientific-practical engineering accomplishments achieved in just one of 30 institutions authorized with research and innovation, which were later implemented into a vast listing of scientointensive industrial products, manufactured at the production facilities of the domestic industrial complex.
The paper highlights the valuable scientific achievements of some outstanding personalities – founders of scientific schools of reference in engineering, which have had a positive impact on the development and consolidation of engineering sciences and engineering as a whole nationally and internationally.
For better understanding of the context of the treated theme in this book I feel indebted to give some specifications.

● The intellectual potential of Republic of Moldova impoverished in the early postwar period due to imposed in 1940 and 1944 massive refuge of intellectuals over the Prut river, and also by recruiting of young people on two fronts of the war, including waves of deportations and organized hunger etc. - has demonstrated enormous capacities for spiritual and identity regeneration, for recovery in a very short terms of the intellectual elite on all dimensions of a creative society, so that the achievements diversity of the complexity stated in this paper can fit during a lifetime.

● Due to the positive impact of the science at the crossroads of the immediate years before and after gaining independence, the Republic of Moldova sets the state budget in a proportion of 54-61% by industry and the agricultural sector - with only 0.152% of the USSR territory - ranks on the sixth place according the total amount (!) of agricultural production among 15 soviet republics,... mistakenly equaled and impoverished by obscure pricing policies.

● Republic of Moldova has been developing as an industrial-agrarian country with significant capacities for research, technological development and innovation, with an infrastructure composed of 107 research institutions and imposing human potential that ensured the production of material and intellectual scientointensive goods.

● The funding of science is "The Litmus Test" which denotes the degree of understanding by the state structures that Republic of Moldova can affirm as a prosperous state and can offer its citizens a decent living only by supporting and expanding of the production of material and intellectual scientointensive goods.
Unfortunately, in the period following the independence, the state of affairs is different in comparison with 1985: in 1992 the science funding from the state budget decreased by 2.5 times; in 2002 – by 13 times; in 2005 – with 16%; and in 2016, engineering sciences funding was reduced by 26 times in comparison with 1987.

● The economic development in the industrialization period (1960-1990) correlated to scientific research development, reveals a proven fact: Republic of Moldova can thrive by relying on the gray matter, but this requires that science and education should not be only declarative priorities but also priority funded.
Keywords: Engineering sciences, scientific schools, electro erosion, mass and heat transfer, space technology, precessional planetary transmissions.

... Astfel , pe principii de alternativă se asigură concursul de idei și de soluţii tehnice inovative ale echipelor de tineri cercetători implicaţi în proiectele educaţionale de cercetare-dezvoltare ale subsistemelor de bord ale MS. Odată cu elaborările efectuate în original [1,9], echipele de cercetători în baza studiilor de caz propun variante ale componentelor de bord disponibile COTS (comerciale) însoţite cu analize de compatibilitate, masă, gabarite, cost, inclusiv de asigurare a interschimbabilităţii și fiabilităţii MS în ansamblu. Laboratorul SBNMS este dotat cu calculatoare performante , cu staţii de proiectare asistate de calculator cu aplicarea softurilor moderne de proiectare în 3D și de analize comparative, inclusiv de simulări computerizate a proceselor tehnologice (foto 1). ...
This article reflects the vision of authors on the prospects of international cooperation in the field of satellite technologies, which are developing rapidly with a spectacular expansion in various areas of scientific, economic and social interest. In most European countries the concerns in satellite technologies are gaining more ground in the universities and research centres attracting in research new adherents, especially among young researchers.
Satellite technology area is becoming more prominent in the development of educational projects and
therefore continuously increases the number of universities that launch their own satellites with the most
diverse scientific missions and goals. An example of the dynamic development of space technologies is
Romania. In recent years the thematic variety of scientific research has expanded rapidly, new scientific
schools and institutional structures of research - development in the area of space technologies were opened.
The Republic of Moldova takes the first steps in this field. After signing the Agreement of Association
of the Republic of Moldova to the European research – innovation programme – Horizon 2020 in June 2014,
new opportunities open regarding the participation of Moldovan academic community in European programmes for the development of space technologies.
Keywords: satellite, earth stations, satellite technologies, orbital flight, attitude control.
This report constitutes a review of the accumulated experience and the
challenges faced by the TUM Space Technologies Center team when developing
the TUMnanoSAT nanosatellite within the KiboCUBE program, supported by
JAXA and UNOOSA. The report is intended to familiarize the readers with the
proposed approaches and solutions to the design and realization of the subsystems
of the nanosatellite, as well as with the organizational problems at its launch. This
report is addressed to students, masters and doctoral students, as well as engineers
designing equipment and installations based on advanced technologies.
