From 22 March to 2 April 2021, 30 college students from 13 distinctive ESA Member States and Canada participated in the first on the internet edition of ESA Academy’s Earth Observation Satellite Procedure Design and style Teaching Class. Just about every afternoon, the students went via the entire style and design and growth cycle of Earth Observation (EO) satellite units in collaboration with ARES, the Association of Retired ESA Staff.
An significant section of the instruction system throughout the two weeks was to allow the pupils style a up coming technology Copernicus ocean observation technique phase-by-stage, specifically the ‘Sentinel-3 Following Generation’ consisting of a pair of satellites, carrying altimetry and optical payloads, respectively.
“We have expanded and improved the lectures as effectively as the carry out of the team task as as opposed to the pilot 2018 version. The important problem for us was to generate an efficient teamwork in an on the web natural environment, with the college student teams on a person hand, and the trainers on the other hand, all connected ‘live’ by way of superior movie-conferencing and chat services,” defined a single of the organizers.
Immediately after the welcome and introduction session to the class, an inspiring overview of Earth observation satellite techniques and an introductory lecture on remote sensing techniques marked the authentic start out of the training study course.
The next day, the pupils had been taught the importance of starting with observation needs as described by customers, and the methodology to derive procedure/engineering specifications. The numerous probable orbits and launchers for EO missions were also discussed, followed by the initially group undertaking session on orbit choice. Earning use of ESA’s SamiEdit and ESOV orbit simulation applications, the students acquired to fully grasp the mission parameters that push the choice of the orbit.
Because the very first group task session, the pupils were being divided in project teams wherever each and every university student within just a team was in cost of a presented engineering discipline.
Before the 2nd group undertaking session began, in which they experienced to layout the microwave devices on board the altimetry satellite, the college students relished successive lectures on microwave distant sensing instrumentation, starting up with the electromagnetic wave principle, then progressing to the ideas of radars and radiometers for quantitative Earth remote sensing.
To close out the 1st week, their past topic was optical instrumentation. Lectures on standard place optics and optical payloads delivered the pupils with the important info to be in a position to layout the ocean colour instrument for the optical satellite through the 3rd team task session.
“I like how the lectures complemented properly our venture and how the professionals were being all extremely motivated and associated in the challenge. It was obvious that every person involved used a fantastic exertion to aid the college students to master as a great deal as attainable in this confined time period of time,” suggests a Swiss college student from Ecole Polytechnique Fédérale de Lausanne (EPFL).
There were being no indications of slowing down, as the 2nd 7 days acquired underway with a lecture on threat administration and technological know-how progress, adopted by detailed explanations on how EO satellites are built and their payloads accommodated. All over this 7 days, the college students also discovered how satellite elements and tools are assembled, built-in and confirmed (AIV) by tests, in addition to attaining thorough insights into the start strategies, in-orbit verification as very well as floor phase layout and functions ideas.
The do the job of coming up with the Sentinel-3 Future Era intensified in this next week. The finish-to-close procedure principle elaboration incorporated the house phase style, interface technical specs, ground segment design and the functions notion definition. Students’ tasks consisted of many ways, ranging from e.g. calculations of mass, ability and knowledge amount budgets to figuring out how their satellites would in shape into the launcher fairing.
The ultimate day was committed to presenting the consequence of the group tasks to the ESA and ARES authorities. All groups worked hard on their initiatives and offered their effects to the trainers, who were positively amazed by the large high-quality of the attained system definitions. The students efficiently shown their talents to implement their obtained awareness into the structure of an EO procedure.
“The entire program was an participating, difficult, and worthwhile team expertise that taught me a great deal about finish-to-close architecture of past, current and foreseeable future EO space missions whilst giving several exciting insights about all their unique aspects provided by passionate specialists. A superb working experience assured to depart attendees with further awareness of the topics included and also with lots of enjoyment moments to be lived with fellow college students from all about Europe and further than!” remarkedt system an Italian university student from the College of Naples, Federico II.
On completion of the class, the university student groups had been evaluated on the foundation of their staff get the job done and respective satellite style. They were being offered with a study course transcript that, along with their certificate of participation, could enable them to gain ECTS credit(s) from their respective universities.
