The Geostationary Transfer Orbit Satellite (GTOSat) is a mission done in collaboration with NASA Langley Research Center, the University of Colorado, Boulder, and the Aerospace Corporation Inc.
GTOSat’s primary goal is to advance the quantitative understanding of acceleration and loss of relativistic electrons in the Earth’s outer radiation belts. GTOSat is a 6U CubeSat mission that will measure electron spectra and pitch angles of both the seed and energized electron populations simultaneously. The high quality and particle field measurements of this instrument enables direct measurements of spectral and pitch angle evolution of the outer radiation belt.
The GTOSat mission was developed to serve as a pathfinder for new radiation-tolerant technologies that could enable the deployment a constellation of small satellites beyond low-Earth orbit to gather simultaneous, multi-point measurements of Earth’s ever-changing magnetosphere.
