Payload

ELFIN’s primary payload consists of a fluxgate magnetometer and two energetic particle detectors. These instruments are being developed in-house by UCLA staff members in the Earth, Planetary and Space Sciences department.

Attitude Determination and Control

The ELFIN ADCS (Attitude Determination and Control Subsystem) is responsible for designing, testing, and implementing the mechanisms which precisely acquire and control ELFIN’s attitude (i.e. orientation and spin vectors) in orbit.

Command and Data Handling

The Command and Data Handling (C&DH) subsystem is responsible for processing commands, collecting data, and monitoring the satellite. C&DH is composed of the Flight Computer, the Watchdog, and ADCS Main PIC, and the Power PIC.

Thermal Cover Pic.jpg

Thermal 

Spacecraft in Low Earth Orbit (LEO) operate in an environment that produces temperature extremes from as low as -100 ºC to as high as 100 ºC. At these extremes, critical spacecraft components such as batteries and avionics boards cease to function. The job of the thermal team is to predict how ELFIN’s components will thermally respond to the flight environment and to develop methods for preventing the spacecraft from exceeding temperature restrictions.

A Student-Led Mission

UCLA students are working on all subsystems, including Attitude Determination and Control, Communication, Command and Data Handling, Flight Software, Payload, Power, and Structures. The majority of the final spacecraft will be constructed in-house by UCLA students, with avionics and bus programming by UCLA students and structure fabrication in an in-house machine shop.
