The kinetic unit ensured the Minisat 01 maintained a favorable position to maximize sunlight incidence on the solar panels in addition to stabilize the spacecraft on its 3 axis.
[13] Being the result of the joint efforts of INTA and the University of California, Berkeley, this device was to conduct spectrographic observations of diffuse EUV radiation in the interstellar medium to examine the Mesosphere's composition.
This allowed to compare and filter the readings obtained to minimize systematic errors caused by the ionizing nature of EUV, thus, ensuring a higher degree of precision.
Under the grating, the Multi-Channel Plate (MCP) detectors with wedge and strip encoding are allocated, facing the exterior through a lens which provides them with 26º x 8º FOV and four possible positions.
[14] Developed by the Technical University of Madrid the CPLM was experimentation module created to study the behavior of fluids when allocated inside axis-symmetric bridges under conditions of microgravity.
This unit was itself built with a motor, able to change the direction of the bridges and to reset the experiment, and an accelerometer which measured the forces acting on the test fluid.
The module was allocated inside a cylindrical container which also held the power supply, several temperature and pressure sensors, and a back-up memory card.
The device was to incorporate some cutting-edge technology for its time, such as HgI2 emerging detectors developed by the Centro de Investigaciones Energéticas y Medioambientales (CIEMAT) capable of providing accurate readings on the operating energy range and a high degree of thermal resistance and a very good efficiency-weight ratio.
Besides the sensing sub-unit, LEGRI incorporated a filtering unit made of a mechanical collimator supported on a honeycomb tungsten plate which is allocated in front of the detectors, a high voltage power supply needed to feed the device, and a processing unit which manages data and provides continuous attitude readings on the satellite to ease image reconstruction while avoiding signal noise.
The time control during the different phases of deployment was ensured by a pyrotechnic nut, responsible for maintaining the system's integrity until the firing of a pyro-kintetic charge which would signal the conditions were met to begin the whole placement process.
