Machine Learning For Early Satellite Anomaly Detection, Pablo Bernal-Mencia, Kelsey Doerksen, Chen Yap

Small Satellite Conference

Despite its recent disruption to many engineering fields, incorporating machine learning into satellite operations is difficult due to the associated performance restrictions with the relatively small amount of available data during a satellite’s operating lifetime; a satellite needs to be operating for several months to years in order to grow a dataset able to be used in machine learning. That is the reason behind its historically limited application to active satellite operations, whereas a posteriori applications to past missions can be found in the literature. Recently however, the eruption of mega-constellations of satellites, whose hardware, software, and orbit are almost …

Efficient Smallsat Operation Using Scibox, Kristin Fretz, Ralf Perez, Teck Choo, Annette Mirantes, Warren Chen

Small Satellite Conference

Planning and commanding a space operation is inherently a very complex task requiring highly skilled operators from various disciplines coordinating in a timely manner to ensure both smooth and successful operation. This process can be performed manually, however, resolving conflicts quickly becomes an intensive iterative process that underuses a space system’s resources and renders it less responsive to sudden schedule changes. Increasingly complex space missions combined with the desire to maximize efficiency require a different approach. Responding to these challenges is SciBox, an autonomous planning and commanding system and a technology enabler for space operations, developed by the Johns Hopkins …

Ph 11.3 Enhances The Solubility Of Potassium Silicate For Liquid Fertilizer, Brendan Fatzinger, Bruce Bugbee

Nutrients

Consistent delivery of up to 1 mM silicon (Si) to the root-zone is beneficial for plant health, but the maximum solubility of silicon is only 1.7 mM between pH 4 and 8. This makes Si difficult to concentrate and add through a proportioner in liquid fertilizer systems. The solubility of Si begins to increase with increasing pH above 9. We added potassium silicate (K₂SiO₃) and fumed silica (SiO₂) to RO water that was pH adjusted to pH 5, 8, 9, 10, or 11 with either KOH or NaOH. Samples were filtered and dried to …
