Deployable Multi Panel Solar Array for Low Cost 1U Cubesat Missions
1st IAA Latin American Symposium on Small Satellites: Advanced Technologies and Distributed Systems March 7 - 10, 2017, San Martín, Buenos Aires, Argentina DEPLOYABLE MULTI PANEL SOLAR ARRAY FOR LOW COST 1U CUBESAT MISSIONS Cdr. Ronnie Nader, Sys. Eng. Gerard Nader Drouet, ASA/T Cosmonaut Spacecraft Systems Eng. - EXA Space Operations Director - EXA DEPLOYABLE MULTI PANEL SOLAR ARRAY FOR LOW COST 1U CUBESAT MISSIONS • EXA is the Ecuadorian Civilian Space Agency, a civilian NGO created in 2007, in charge of the administration and execution of the Ecuadorian Civilian Space Program – ECSP. • The ECSP is a young and modest space program, based on indigenous technology, national effort, government and private funding and international cooperation. • The ECSP has an unmanned space program and a manned space program. DEPLOYABLE MULTI PANEL SOLAR ARRAY FOR LOW COST 1U CUBESAT MISSIONS • In 2010 EXA began the design and construction of the first Ecuadorian satellite, the NEE-01 PEGASUS. • PEGASUS and its twin KRYSAOR were completely built in the country with indigenous technology, fabrication methods, tools and testing facilities that were developed exclusively for the EXA-USP (Unmanned Space Program) • Facilities as the Space Environment Simulation Chamber or the GOLEM Magneto Acoustical Vibration Facility were also built for testing and development of indigenous satellite technology DEPLOYABLE MULTI PANEL SOLAR ARRAY FOR LOW COST 1U CUBESAT MISSIONS • The NEE-class satellites were designed as a 1U cubesat form factor, however, as soon as the initial design was complete, a limitation was discovered in the power budget calculations due to main payload power demands and budget constraints. • A lack of space for enough solar cells, so we decided to add a pair of multi-panel solar arrays or ‘wings’ to address this deficiency.
