The Effects Of Electoral Outcomes And Cross-Party Relationships On Affective Polarization, Jenna Pedersen

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation explores several under-studied aspects of affective polarization through four chapters. The first chapter discusses the history of polarization research and the measurement challenges facing polarization scholars. The second chapter analyzes how electoral outcomes differentially influence Democrats' and Republicans' inparty, outparty, and general affect. I find that winning elections affects both outparty and inparty attitudes, but the size and direction of these effects varies by party: electoral success reduces Republicans' inparty affect, but for Democrats success reduces outparty affect. The third and fourth chapters contain survey experiment data measuring the effects of cross-partisan relationships. I find that positive relationships …

Effect Of High Solar Activity On The Orbital Decay Rate Of The 3u Cubesat Dora, Joseph Dubois, Daniel Jacobs, Siddharth Vaidyanathan

Small Satellite Conference

CubeSats developed at universities seldom have propulsion due to cost and complexity constraints and are very commonly deployed from the ISS into orbits where atmospheric drag is significant. Without propulsion, the time to re-entry is a function of the cross section to mass ratio and the space weather. Many cubesats have limited ways of decreasing ram cross section, e.g. pointing into the wind. Hard radiation from solar activity inflates the atmosphere and increases drag. Since the beginning of the cubesat era, the Sun has been unusually quiescent, at a level not seen for 200 years, which has biased expectations for …

Proliferation in low earth orbits, both operational satellites and defunct or debris items, poses a significant challenge to the long-term sustainability of space operations, and the difficulties in tracking and measuring mm-scale has increased the uncertainty of contemporary statistical models like the NASA Orbital Debris Engineering Model (ORDEM) and ESA MASTER and their statistical debris flux predictions. This uncertainty both complicates orbital mission risk assessment and impedes remediation efforts. This paper develops a CubeSat mission that informs these statistical models through in situ flux determination, providing a comparison of debris flux levels in Low Earth Orbit (LEO). The optimum orbit …

Development Of Model Predictive Control Approach For Precise De-Orbit Of Nanosatellite Using Aerodynamic Drag, Tian Xie, Takashige Suzuki, Maximilien Berthet

Small Satellite Conference

Small satellite missions in low Earth orbit (LEO) can utilize propellant-free aerodynamic drag for maneuvering, but achieving precise orbit control is challenged by non-linearities and uncertainties. This paper proposes a nonlinear model predictive control (NMPC) framework designed for precise trajectory tracking under these conditions. By focusing on following a given reference path, our NMPC controller overcomes time-varying perturbations (e.g., J2, J3, J4 effects). We validated this tracking-focused approach with simulations incorporating stochastic atmospheric models. Monte Carlo analysis, using controlled de-orbiting profiles as reference trajectories, demonstrates that our NMPC system provides a powerful tool for enabling precise, propellant-free maneuvers. This work …

Small Satellite Conference

This paper proposes a novel concept of quasi-two-dimensional SAR (synthetic aperture radar) satellites, SAR DiskSats, featuring a deployable passive slot array antenna (De-PSAA) that can be compactly folded within the quasi-two-dimensional (Q-2D) satellite body. This Q-2D configuration allows for potential flexible solar cell sheets to be installed on the backside of the antenna, as the antennas do not dissipate heat. This satellite configuration is also suitable for stacking within a rocket fairing for the mega-constellation launch of SAR DiskSats into VLEO (very low Earth orbit). The proposed DiskSat's thin edge cross-section reduces aerodynamic drag, enabling the satellite to operate at …

Small Satellite Conference

Optical Earth Observation (EO) sensors can be significantly affected by atmospheric conditions, particularly cloud cover, which can obscure their images and reduce the information content in the final image. It is estimated that over 50% of the Earth’s surface is covered by clouds at any given moment. As a result, up to half of the data captured by visible EO satellite imagers is rendered unusable for most applications. Transmitting this unusable data, even in a compressed form, unnecessarily utilises valuable communications downlink bandwidth. This is particularly acute for hyperspectral EO missions, where the tens to hundreds of bands per acquisition …

Novel Global Navigation Satellite System Receiver For Characterization Of Ionospheric Scintillation And Plasma Bubbles With A Cubesat Swarm, William Gullotta, John Braun, Jan-Peter Weiss, Nicholas Pedatella, Qian Wu

Small Satellite Conference

Ionospheric scintillation and equatorial plasma bubbles (EPBs) are phenomena related to turbulence and depletion in the plasmas in the ionosphere. EPBs are depletions in the plasma density in the equatorial region in the post-sunset period. These depletions can lead to turbulent irregularities in the amplitude and phase of communications signals, called scintillation. Scintillation also occurs in the polar regions, where it is caused by particle precipitation and convection. EPBs and scintillation in low- and high- latitudes both have an impact on the quality and availability of space-based communication and navigation systems which leads to a high demand for observations from …
