SUCHAI (Satellite of the University of Chile for Aerospace Investigation) is the first chilean 1U CubeSat developed by undergraduate students, engineers and professors of the Electrical Engineering, Physics and Mechanical Engineering Departments of the Faculty of Physical and Mathematical Sciences (FCFM) at Universidad de Chile. The main goal is to learn the whole process of designing, building/integrating, launching and operating a picosatellite.

SUCHAI mission carries the following payloads:

  • Langmuir probe: the main scientific goal of this payload is to study the ionosphere in synchronization with incoherent scatter radar (ISR) by take simultaneous measurements of electron density variations in the ionosphere.
  • Electronic out of equilibrium: simple RC experiment to study the out of equilibrium fluctuations in a hostile enviroment.
  • Thermal Experiment: Study of heat dissipation for electronic devices in vacuum environment.
  • Camera: a digital camera to study the feasibility of observing earth form space with cubesats.
  • A GPS receiver to get the position of the spacecraft and to learn the process for permission of it. In future missions dual-frequency GPS receiver might be used for Total Electron Content (TEC) and/or water vapor (WV) determination (via data ocultation technique).
