The paper introduces a power supply and Radio Frequency (RF) signal routing architecture design for a foldable phased array transceiver intended for next-generation space communication systems. The transceiver is built using four 6-layer rigid-flexible substrates, enabling a high layer count and complex electrical routing. Using a DC-DC converter and changing the voltage from 5.5V to 1.2V reduces power loss by 43%. Three types of transmission lines are used to enable folding. These lines allow for complex, low-loss RF distribution. A prototype rigid flexible board was fabricated for evaluation, and power supply and RF were evaluated.

Small Satellite Conference
This paper introduces the technology for radiation tolerance of Ka-band deployable phased-array antenna to provide wider communications infrastructure. Radiation in outer space degrades the performance of electronic devices. Furthermore, because the BFIC on the deployable phased-array antenna cannot be shielded due to the antenna structure, higher radiation tolerance is required than general aerospace ICs. The amount of radiation tolerance required was calculated and the high radiation tolerance technology of the BFIC was introduced, which was evaluated from the measurement results be exposing the BFIC to 3 Mrad radiation which exceeds the conventional measurement dose.

Applying Machine Learning To Equatorial Plasma Bubble Now Casting On Cubesats, Benjamin Lewis, Shawn Jones, Charles Swenson, Kevin Moon, Mario Harper
Small Satellite Conference
Equatorial plasma bubbles are a space weather phenomenon that occur at low latitudes within the Earth’s ionosphere. These bubbles are regions of low-density plasma that form at the base of the ionosphere and expand upward through the peak and into the topside. They form in the early evening and persist through the nighttime, stretching north and south along magnetic field lines and effecting a sector of longitudes a few degrees wide. These bubbles cause scintillations on radio signals that pass through them, disrupting the performance of systems, such as GPS, throughout the night in regions around the Earth. Due to …

Satellite design faces the challenge of optimizing external surface area to accommodate various components, such as solar panels, antennas, sensors, and technology demonstrations. For small satellites, solar cells occupy most of the external faces, offering little surface area for other functions. To solve this problem, researchers and developers have attempted to create an S-band patch antenna that can integrate with a solar cell, providing higher gain and maximizing solar panel power generation. The most common option is to create a meshed patch antenna on a transparent substrate, increasing optical transparency. Often, this involves using conductive ink printed onto a transparent …

In impact threat assessments of planetary defense options, the aim is to understand how seismic waves travel through the debris, either modifying its shape or its surface. Seismic disturbances can destabilize loose material resting on the slope, causing downward flows. With the Microgravity Experiment for Asteroid Regolith Sound Velocity (MESSAR), it is proposed to measure the sound velocity within the simulated asteroid regolith in the microgravity environment of the International Space Station (ISS). The payload contains several granular samples of simulated asteroid regolith that will be used to measure the influence of grain size and confining pressure on the wave …

Navigating Regulatory And Ethical Hurdles With Hexsat: A Detachable Net Casting Spider-Inspired Space Debris Removal Concept, Leonor Merino Osornio, Mostafa Hassanalian
Small Satellite Conference
As the amount of space debris in orbit continues to increase, the need for methods of mitigating space debris becomes urgent. Drawing inspiration from nature, a net casting spider-inspired method of space debris removal has been proposed. This method, embodied in the HexSat design, features six separate wedges that can deploy to form a net for capturing debris. Once the target debris is captured, HexSat will intentionally reenter the atmosphere, where it will burn up. Any missions aimed at cleaning up space debris will face numerous challenges posed by international space regulations. To assess these challenges, a hypothetical scenario was …
