Leveraging Persistent L-Band Leo-To-Geo Relays For The Orchestration Of High-Bandwidth Optical Inter-Satellite Links, Jonathan Maier, Skylar A. Cox

Small Satellite Conference

As the already tremendous demand for data transfer in Low Earth Orbit (LEO) grows, Free-Space Optical (FSO) communication has emerged as a critical capability due to high data rates and inherent resilience attributes. However, the operational complexity of FSO, specifically the Pointing, Acquisition, and Tracking (PAT) process, requires significant operational planning. The narrow beamwidth of optical terminals requires precise spatial coordination, resulting in latency during link establishment, heavy reliance on scheduled ground-based commanding, and an impediment to agile, responsive, and ad hoc operations.

This paper presents a novel orchestration architecture utilizing Viasat’s L-band space relay network as a persistent, always-on …

Evaluating Performance Of Hardware-Accelerated Vessel Detection Algorithms, Michael Tietz, John Warner, Quinton Davidson, Douglas Carssow

Small Satellite Conference

Earth observing satellites contribute to the monitoring of maritime activity by enabling large-scale coverage of open water. For example, spacecraft data can be used to monitor and combat Illegal, Unreported, and Unregulated (IUU) fishing that occurs in coastal and international waters across the globe. However, information latencies limit the utility of space-based sensors for operational users who need real-time situational awareness. These limitations are especially pronounced for small spacecraft with limited power generation and downlink capabilities. In recent years, the devices and tools that enable edge computing and near real-time downlink from small spacecraft have improved substantially. Equipped with these …

Metadata-Conditioned Dark-Frame Modelling And Hsdr-Scanfusion Denoising: A Physics-Informed Independent Tool For Low-Cost Hyperspectral Small-Satellite Calibration, Nooh Adnan, Kyaw Thiha, Raffael Gil Dela Cruz, Li Cheng Zheng, Faijul Amin, Areeba Khan, Sameha Tasnim, Sung Jegal, Yunhan Bao, Iliya Shofman

Small Satellite Conference

Hyperspectral imaging in the shortwave-infrared spectrum is valuable for orbital Earth observation, but its use on low-cost, resource-constrained small satellites is limited by thermally dependent dark current, fixed-pattern noise, and intermittent access to matched calibration frames. Traditional mitigation through active cooling, shutters, or frequent dark-frame acquisition can be difficult to accommodate within small-satellite mass, power, volume, and operations budgets. This paper presents a physics-informed independent calibration tool that reconstructs condition-matched dark response from acquisition metadata rather than relying on hardware-heavy calibration at every operating point. The framework combines a stochastic dark-noise simulator, a metadata-conditioned neural dark operator that predicts spectral-spatial …

Development Of Wavelength-Division-Multiplexed All-Optical Relays For Low-Earth Orbit Free-Space Optical Communication Networks, Travis Jones, Justin Cook, Chris Krush, Doruk Engin, Keith G. Petrillo

The design sought to optimize links for LEO-based networks incorporating appropriate span lengths and optical terminal specifications. We incorporate an add-drop multiplexer for rerouting signals and designed the system to be flexible over span lengths with a nominal range of 1,800 km. We performed several tests of the nominally 60 dB gain amplifier to assess link dynamics unique to free space optical communications (FSOC) including the impact of pointing jitter, nonlinearities, gain flattening, and wide-band filters on an …

Event-Driven Spacecraft Operations Demonstrated On Mms, Miles Bengtson, Alexander Barrie, Joseph Patton, Liam Greenlee, Paul Wood, Marcus Piquette, Russell Bjella, Matthew Chang, Joshua Paul

Small Satellite Conference

Operations engineers face the challenging task of capturing high-value science data while maintaining spacecraft health and functionality and responding to a dynamic space environment using limited information. This task is becoming increasingly complex as missions involve increasingly large numbers of spacecraft, target more elusive science signatures, and operate under growing budget and staffing constraints. Conventional pre-programmed time-sequence commands become increasingly burdensome for multi-spacecraft missions and are fundamentally incapable of reacting to rare, transient science events in real time.

To address this challenge, we have developed MEDOS: the Module for Event-Driven Operations of Spacecraft. Unlike machine learning and neural-network approaches, MEDOS …

Recovery Of Grus-1e From Magnetic Torquer Loss Using Data-Driven Open-Loop Attitude Steering, Nader Ganaba, Takanori Iwata, Minoru Kurata

Small Satellite Conference

In typical low Earth orbit (LEO) operations, the inability to remove excess angular momentum often leads to the decommissioning of a satellite. This paper presents the on-orbit recovery of GRUS-1E, a hundred kg class Earth observation satellite in Axelspace Corporation’s GRUS-1 constellation. The recovery followed the permanent loss of magnetic torquer commanding capability, which in turn disabled the satellite’s nominal reaction wheel momentum unloading. In addition, the satellite experienced persistent disturbance torques that significantly exceeded the combined contributions predicted by standard models, including gravity gradient, solar radiation pressure, aerodynamic drag, and the estimated residual magnetic dipole moment. The magnitude of …

Recursive Artificial Intelligence Training And The Homogenization Of Discourse, Sam Hemesath

Political Science Honors Projects

As Large Language Models (LLMs) begin to produce text on the internet, the same repository from which training data for LLMs are scraped, LLMs will start to train on data they produced. What will happen to future models when LLMs are trained on their own text? Scholars have raised concerns about the possibility that LLMs homogenize language and discourse. These concerns are further exaggerated as LLMs begin to infect their own repositories, marking a turn from human-produced training data sets. In this paper I simulate a recursive training loop by prompting a popular open-source LLM with 1000 prompts and using …

Esa Scout Hydrognss Early Mission Results, Martin Unwin, Alex Da Silva Curiel, Ben Stern, Jean-Pascal Lejault, Nazzareno Pierdicca

Small Satellite Conference

The ESA Scout HydroGNSS mission demonstrates a new generation of GNSS reflectometry (GNSS R) capabilities for hydrological climate monitoring from small satellites. HydroGNSS measures soil moisture, freeze–thaw state, inundation, wetlands and above ground biomass by exploiting both traditional incoherent Delay Doppler Maps (DDMs) and several innovative signal types not previously available from spaceborne GNSS R missions. Early in orbit results confirm successful acquisition of signals from Galileo, dual polarisation measurements, coherent complex channel data and reflections at the second GNSS frequency (L5/E5a). These enhanced measurements exhibit stronger than predicted performance and are expected to significantly improve retrievals of climate relevant …

Melodizing Modern Power: Giacomo Puccini And The Demands Of Thematic Development, Claire Kelly

Music Honors Projects

This paper examines Italian composer Giacomo Puccini’s processes of thematic development in three operas, La Bohème (1896), Tosca (1900), and Il Tabarro (1918). Puccini’s thematic development has been a point of contention for many musicologists and critics. Critics of his own time found his thematic development style to be inconsistent; some regarded his melodies as fragmented and lacking cohesion. Since then, biographers and critics such as Michele Girardi, Mosco Carner, and Alexandra Wilson have reiterated and re-examined these claims. Taken together, my three case studies conclude that Puccini’s multivalent style of thematic development is meant to depict the various effects …

An Analysis Of The Effects And Implementations Of The Early Literacy Grant In Arizona, Alicia Severiano Perez

Mathematics, Statistics, and Computer Science Honors Projects

Over the years, states have implemented Science of Reading (SoR) frameworks to address low literacy levels. The Early Literacy Grant (ELG) in Arizona funds and supports such frameworks for schools serving low-income students. This paper is the first to explore the grant through interrupted time series modeling to evaluate effectiveness and text analysis to understand its implementation. We do not find clear evidence of positive effects caused by the grant, other than some cases, such as Yuma County. Schools typically allocate funds toward salaries and hiring instructors. These findings raise questions about whether its allocations should be closely monitored.

Unsustainable Stories: Agricultural Knowledge On The Great Plains, 1880-1934, Philomena Shuffelton-Sobe

History Honors Projects

This thesis explores stories about how people farmed and learned about farming on the Great Plains from 1880-1920 through three inter-connected narratives: the Allotment system, agricultural education programs at federal Indian Boarding Schools, and the rapid rise and fall of the Dry Farming movement. These systems were built on stories about how people should live with and on the land that promoted unsustainable, destructive ways of farming and knowledge production. This scholarship places Assimilation Era agricultural education for Native and non-Native farmers within the context of the increasing reliance on systems and science and the institutionalization of agricultural knowledge.
