Cyclone Global Navigation Satellite System (CYGNSS)

Between 2015 and 2016, SwRI designed, analyzed, fabricated, and integrated NASA's Cyclone Global Navigation Satellite System (CYGNSS) at our campus in San Antonio, Texas. Launched in December 2016, CYGNSS is a constellation of eight microsatellites designed to collect data based on GPS satellite signals to measure wind speeds and hurricane intensification.

SwRI integrated multiple components and subsystems for each of the eight microsatellites. After assembling the microsatellites, our team inspected interfaces and tested subsystems. Testing and evaluation include environmental testing, and electromagnetic compatibility and interference. We also tested the units in a large thermal vacuum chamber at the SwRI campus.

CubeSat to study Solar Particles (CuSP)

The CubeSat to study Solar Particles (CuSP) is one of a dozen shoebox-size payloads, called CubeSats, that will hitchhike into interplanetary space aboard EM-1, the first unmanned test flight of NASA’s giant new Space Launch System (SLS). The SLS rocket is designed to eventually carry astronauts to the Moon and Mars aboard the Orion spacecraft.

CuSP will study Solar Particles in interplanetary space, be a Pathfinder for creating a network of “Space Weather Stations”, strengthen the case for CubeSats as a viable platform for performing ‘High Value’ Science, raise the TRL of the SIS instrument for future missions
