Description
The Science Diagnostic Subsystem (SDS) is one of the main subsystems in LISA (Laser Interferometer Space Antenna) mission of the European Space Agency (ESA) and represents the Spanish contribution to the mission. The SDS will provide 144 temperature sensors, 18 magnetometers, 3 radiation monitors, 6 pick-up coils and 12 heaters. Extreme precision and stability are required for these sensors in order to minitor environmental fluctuations. The stringhten requirements in LISA requires further development and testing. This is the idea behing the ILIADA project.
ILIADA is an in-orbit demonstrator (IOD) planned to fly in 2026 as a part of an Earth Observation satellite mission in the framework of the New Space Strategy from the Generalitat of Catalonia. ILIADA project will implement a first version of the Scientific Diagnostics Subsystem (SDS) sensors. The primary goal of ILIADA is to raise the TRL of the new technologies and sensor elements for LISA. It will include temperature sensors, magnetometers (AMR and MEMs based) and a radiation monitor. The scondary objective of ILIADA is to detect the crossing of the spacecraft through the Birkeland currents, i.e. a set of electric currents that flow along geomagnetics field lines connecting the Earth's magnethosphere to the Earth's high latitude ionosphere, by exploiting the use of high precision sensors on-board.
