	abstract = {<p>Total Electron Content (TEC) is a key ionospheric parameter that affects HF propagation and introduces delay in Global Navigation Satellite System (GNSS) signals. This poster provides an overview of what a GNSS receiver measures and how those measurements can be used to estimate TEC. I introduce the primary GNSS observables (code or pseudorange and carrier phase), explain how dual-frequency observations isolate the ionospheric contribution through dispersive delay, and outline the standard steps used to compute slant TEC and relate it to vertical TEC using simple mapping assumptions. I also discuss how low-cost, off-the-shelf dual-frequency GNSS receivers commonly marketed for Real Time Kinematic (RTK) applications can support TEC estimation when their raw observables are available, and how a distributed network of such receivers aligns with the HamSCI citizen-science model for expanding ionospheric monitoring coverage. Finally, I will show example systems I have built, based on the EclipseNB network from the University of New Brunswick, and briefly note their deployment for operation in Antarctica under the NSF-funded KAGO program, along with progress toward a public guide to help others replicate these stations.</p>

	abstract = {<p>We report on citizen science activities in a physics course and Space Force ROTC training designed to engage undergraduate students and cadets in the HamSCI Personal Space Weather Station (PSWS) project. The New Jersey Institute of Technology (NJIT) Physics Department offers a senior-level lab course, "Advanced Physics Lab," where students are expected to gain hands-on experience with experimental techniques, instrumentation, theoretical and applied electronics, solid-state electronic devices, and experiments in modern physics by performing quantitative measurements of fundamental physical parameters. In this lab, students work in a largely unstructured environment, where they are provided with equipment and related manuals to conduct experiments with minimal instructor supervision. Traditionally, students have followed preset lab setups, guided by the manuals that accompany the equipment. While this approach helps students relate lab results to established physics theories and principles, its impact has been limited due to a lack of "hands-on" experience and real-world application demonstrations. The HamSCI PSWS project provides an excellent opportunity to address this gap. Through the project, students build and test scientific instruments, using them for investigations that engage them directly in scientific inquiry. This paper presents an evaluation of the impact of this undergraduate class activity on future workforce development, utilizing HamSCI resources.</p>
