SAIL’s space situational awareness project is named OSCOM, which is an Optical tracking and Spectral Characterization system designed specifically for responsive observation and analysis of CubeSats for Operational Missions. The project was seed funded by an NSF RAPID award (#AGS-1450999). The details of the OSCOM system were published in a peer reviewed article in the Sensors journal: Multi-site simultaneous time-resolved photometry with a low cost electro-optics system. By interpreting the optical and spectral features of resident space objects (RSOs), OSCOM is attempting to determine several physical parameters that describe the object: spin rate, deployable status, material makeup and degradation, attitude, and more. Such information can then be used to characterize, categorize, and monitor uncontrolled or unknown space objects, as well as independently provide diagnostic information for operational satellites, big or small. SAIL has multiple Celestron RASA 11″ telescopes, one Celestron 14″ EdgeHD with Starizona Hyperstar, and access to CDK 20″ and DFM 1 m telescopes through the Embry-Riddle Observatory.
Although OSCOM specializes in small satellites and CubeSats in low Earth orbit (LEO), the project team also develops observational and analysis techniques for solving space situational awareness problems with spatially resolved satellites in LEO, satellites in GEO, and debris and near Earth asteroids.
Some of the past and present research activities of OSCOM include:
Robust photometry, spectroscopy, and orbit determination
Spacecraft attitude determination and multi-site simultaneous observation
Mining and heurtistic analysis of large datasets
Telescope and detector characterization and tracking system design
Lucky/speckle imaging and deconvolution methods for high resolution imaging
CubeSat design and ground truth optical characterization
OSCOM is supported by a diverse team of Embry-Riddle students and engineers whose expertise includes small satellites, systems engineering, observational astronomy, data analysis, control systems, and computer science. Research efforts are led by Dr. Barjatya and Dr. von Hippel. For more details on OSCOM, check out the menu at the top of the page, or browse the SAIL@ERAU YouTube channel.
