Optical payloads course
Online course of 300 hours in optical payloads, structured in 6 modules covering space optics fundamentals, detectors and proximity electronics, optomechanical design, calibration and image quality, performance and applications, and a final project, with an assigned technical tutor.
Optical payloads course — studying from Ireland
Ireland's aerospace sector is concentrated in Shannon, Limerick and the Dublin region, with a strong base of maintenance, repair and overhaul, avionics, aerostructures and engine component manufacturing. Multinational suppliers and specialist SMEs serve global airframe and engine programmes, while the Irish Aviation Authority and the European Union Aviation Safety Agency shape certification and airworthiness requirements. Growing interest in drones, urban air mobility and space-related research is supported by university spin-outs and national research centres. Engineers here work on design assurance, systems integration, maintenance planning and compliance across the aviation value chain.
Fees for Ireland: €644 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Will a SEIUM qualification be recognised by professional bodies in Ireland for aerospace work?
SEIUM's qualifications are private, not state-awarded, and are not accredited by any national body. Engineers Ireland is the main professional body for engineers in Ireland and sets its own membership criteria, so recognition is decided by them, not by SEIUM. Aviation safety oversight sits with the Irish Aviation Authority. Check directly with these bodies before relying on any credential for licensing or chartership.
Do Irish aerospace and drone employers value private online engineering qualifications?
Hiring in Ireland's aerospace and drone sector is generally driven by demonstrable skills, relevant experience and, for many roles, recognised degrees. A private qualification may support a CV, particularly alongside practical experience, but its weight is decided by each employer. We cannot promise any outcome. Speaking to prospective employers about how they view SEIUM's programmes is the most reliable way to judge.
Can I study this programme alongside a full-time job in Ireland?
The programme is 100% online and taught in English, so there is no travel and no student visa is needed to study from home. Master's programmes total 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours, so plan your weekly time accordingly. You will have an assigned technical tutor, and fees can be paid in instalments. Some employers offer funding, which you should ask about directly.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so the programme can be combined with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Zemax OpticStudio, CODE V, ESA SNAP, ENVI and QGIS, in free, academic or evaluation versions. Testing is studied through real procedures: design of a three-mirror telescope for Earth observation, calculation of MTF and SNR budgets and atmospheric correction of multispectral images. Assessment is continuous by module, plus the final integrating project.
Standards covered: ISO 19159-1, ISO 10110 (series), ECSS-Q-ST-70-01C, CEOS-ARD Surface Reflectance, ISO 19115-2, ISO 12233, ECSS-E-ST-10-03C.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
