Nanosatellites

SERC explores various new concepts in small and nanosatellite build and design.  Advanced payload integration and deployment from nanosatellites in LEO, digital design tool to autocode generation of onboard software, use of nanosats as parasitic ride-alongs with larger spacecraft, and advanced rendezvous and proximity operations techniques are some of the areas of research.

Nanosat Projects

CAERUS:  USC's first satellite was a 1U Cubesat that became part of a 3U integrated onto the Northrop Grumman Mayflower Mission.  Caerus was the primary communication subsystem that supported the 3U and featured a new quad monopole deployable antenna designed and developed by the SERC team.

 

AENEAS:  USC's most recent flight, Aeneas, modified a 3U (30x10x10cm) National Reconnaissance Office (NRO)-specified Colony I Cubesat bus to address a research thrust of the Department of Homeland Security (DHS).  Aeneas was launched in June 2012 and is still operational today. Aeneas primary payload demonstrated tracking cargo containers over the open ocean with a 1-watt WiFi-like transceiver. This was in support of a DHS effort for open ocean cargo tracking, designed by the primary payload provider iControl Inc.  SERC advancements on the Cubeat included a custom-built deployable 0.5m mesh antenna, and an increase of the attitude control and power generation capabilities of the Colony I bus over the original specifications.

ENDOR:  This project was a full CDR design of a Cubesat with a deployable 20cm inflatable sphere.  The goal was to understand the interaction between a 2-body problem in LEO, and the extent of influence that a sphere that is larger than the original Cubesat body would have on its attitude control, stability, thermal and RF shading, and life on orbit.  This project was in conjunction with students from Huntington Beach High School, Santa Monica College and Dept of Astronautical Engineering at USC.
