Very-low-frequency (VLF) electromagnetic waves, emitted by ground-based sources including lightning and VLF transmitters, can impact the lower ionosphere and magnetosphere through their interaction with the local plasma and energetic particle environments. Quantifying the impacts of these waves requires an accurate assessment of the propagation and attenuation of these waves. The Climatology of Anthropogenic and Natural VLF wave Activity in Space (CANVAS) mission is designed to measure VLF waves in low Earth orbit originating from these ground-based sources. The mission aims to characterize the VLF environment in low Earth orbit to address two main goals: i) constrain the VLF wave injection …

Launching October 2022, the SigNals Of Opportunity P-band Investigation (SNOOPI) is a 6U CubeSat dedicated to demonstrating spaceborne remote sensing of root zone soil moisture and snow water equivalent using signals of opportunity. P-band (240-500 MHz) frequencies are required to penetrate dense vegetation or snow and into the top 200 cm of soil, but this band is heavily subscribed. Rather than transmitting its own signal SNOOPI will observe reflected signals from the U.S. Navy’s Mobile User Objective System satellites. This makes planning observations challenging. The point of reflection is a function of both the transmitter and receiver satellite positions as …

Recently, small satellites such as CubeSats have been applied to a variety of missions such as scientific observations and remote sensing. One of attractive applications that can be relatively easily achieved by small satellites are multi-satellite missions such as formation flight and constellation. As a new method to realize these multi-satellite missions, we propose a method to separate jointed multiple satellite magnetically to generate ΔV without thrusters. To demonstrate the proposed method, we are developing a 3U sized CubeSat called MAGNARO (MAGnetically separating NAnosatellite with Rotation for Orbit control).

Small Satellite Conference
SEASALT is a small satellite mission designed to explore the estimation of salinity in coastal environments using ocean color. A SEASALT constellation would fill the coastal gap by providing coastal SSS observations with much higher spatial resolution (30m) and much shorter revisit times (less than 1 day) on a global scale. Planet’s nanosatellites currently provide daily monitoring of the earth’s surface, as well as coastal locations, at 3-meter resolution. However, they do not have the required bands needed in the near infrared (NIR) for atmospheric correction (they only possess 1 NIR band), thus making atmospheric correction over water very challenging. …

The growing interest in and expanding applications of small satellite constellation networks necessitates effective and reliable high-bandwidth communication between spacecraft. The applications of these constellations (such as navigation or imaging) rely on the precise measurement of timing offset between the spacecraft in the constellation. The CubeSat Laser Infrared CrosslinK (CLICK) mission is being developed by the Massachusetts Institute of Technology (MIT), the University of Florida (UF), and NASA Ames Research Center. The second phase of the mission (CLICK-B/C) will demonstrate a crosslink between two CubeSats (B and C) that each host a < 2U laser communication payload. The terminals will demonstrate full-duplex spacecraft-to-spacecraft communications and ranging capability using commercial components. As part of the mission, CLICK will demonstrate two-way time-transfer for clock synchronization and data transfer at a minimum rate of 20 Mbps over separation distances ranging from 25 km to 580 km. The payloads of CLICK B and C include a receiver chain with a custom photodetector board, a Time-to-Digital Converter (TDC), a Microchip Chip-Scale Atomic Clock (CSAC), and a field-programmable gate array (FPGA). The payloads can measure internal propagation delays of the transmitter and the receiver, and cancel environmental effects impacting timing accuracy. The photodetector board is 2.5 cm x 2.5 cm and includes an avalanche photodiode (APD) and variable-gain amplifiers through which the detected signal is conditioned for the TDC to be time-stamped. This design has been developed from the UF and NASA Ames CubeSat Handling Of Multisystem Precision Time Transfer (CHOMPTT) project and associated MOCT (Miniature Optical Communication Transceiver) demonstration. The TDC samples the signal at four points: twice on the rising edge at set thresholds, and twice at the falling edge at those same thresholds. These four time-offset samples are sent to the FPGA, which combines the measurements for a reported timestamp of the detected laser pulse. These timestamps can then be used in a pulse-position modulation (PPM) demodulation scheme to receive data at up to 50 Mbps, to calculate range down to 10 cm, and for precision time-transfer with < 200 ps resolution. In this paper, we will discuss the designed capabilities and noise performance of the CLICK TDC-based optical receiver chain.

Principles For Designing Origami-Inspired Composite Space Structures With High-Strain Compliant Laminate Joints, Samuel P. Smith, Collin Ynchausti, Spencer P. Magleby
Small Satellite Conference
In space missions, many methods and techniques are used to enable large deployable structures—such as solar arrays, antennas, and radiators—for power, communication, and heat regulation. With origami as inspiration, a new class of self-deployable, self-stiffening, and retractable (SDSR) array has been developed and is reviewed. SDSR arrays are a scalable deployable architecture based on origami flasher patterns. They do not require the aid of external support and actuation structures common in space applications, instead replacing them with strained compliant joints and reeling cables. Aluminum construction has previously been successfully modeled and demonstrated, however, SDSR technology can be greatly improved with …

Utilizing Deep Reinforcement Learning To Effect Autonomous Orbit Tranfers And Intercepts On-Orbit Via Edge Compute, Gabriel Sutherland
Small Satellite Conference
The goal of this project was to create a system capable of autonomous operation with minimal telemetry requirements, while operating within the limits of on-orbit compute and power reserves. Previous work has centered around the use of GPUs to train Deep Reinforcement Learning (DRL) agents for the purpose of autonomous space debris remediation. In the past, a DRL agent was fed orbital tracking data for both debris and active spacecraft to effect target intercepts. However, this approach proved problematic due to large network sizes and expensive computational and training costs. An updated approach utilized Nvidia GPUs to train a Double-Q …

Small Satellite Conference
The present paper shows the innovative deployable reflectarray antenna concept that enables to stow a 1m-by-1m square antenna into 1U CubeSat volume. The antenna is composed of two-layer membranes to obtain an air gap. A one-layer deployable membrane structure was demonstrated by the 3U CubeSat OrigamiSat-1 in 2019. The authors are currently developing two technologies to realize the reflectarray antenna. First, the deployable two-layer membrane structure is to be achieved by using pop-up picture book’s mechanism. Second, reflection elements for the reflectarray antenna that do not cross folding lines are proposed to avoid gain degradation.

Developing Machine Learning Models For Space Based Edge Ai Platforms, James Murphy, John E. Ward, Brian Mac Namee
Small Satellite Conference
On September 3rd 2020, one of the first small satellites equipped with Edge AI hardware was launched. The inclusion of a UB0100 board on PhiSat-1 enabled the use of deep neural networks to provide real-time image analysis on-board an Earth Observation satellite. The primary benefit of this was a 90% reduction in downlink data as the system only transmitted non-cloudy, and thus usable, data. PhiSat-1 and missions like it have started the revolution of satellite-based machine learning, leading ESA and other space agencies to further explore the in-situ deployment of machine-learning models. Other applications that can benefit from on-board space-based …

Distributed space systems are a mission architecture consisting of multiple spacecraft as a cohesive system which provide multipoint sampling, increased mission coverage, or improved sample resolution, while reducing mission risk through redundancy. To fully realize the potential of these systems, eventually scaling to hundreds or thousands of spacecraft, distributed space systems need to be operated as a single entity, which will enable a variety of novel scientific space missions. The Distributed Spacecraft Autonomy (DSA) project is a software project which aims to mature the technology needed for those systems, namely autonomous decision-making and swarm networking. The DSA project leverages a …

An Evaluation Of Potential Compute Platforms For Picosatellites, Ofir Cohen, Sivan Toledo
Small Satellite Conference
What compute platform should picosatellites use? CubeSats, classified as nanosatellites, are transitioning from microcontrollers that cannot run modern operating systems and modern programming environments to Linux-capable compute platforms. As electronics continue to shrink, picosatellite missions are likely to become more common, perhaps using the PocketQube standard. This paper characterizes the requirements that compute platforms for picosatellites should satisfy and analyzes in detail 4 potential platforms. We show that suitable hardware does exist, but that it is not yet supported well enough to allow small teams to use it in satellites or other specialized sensor nodes.

Cubesat Radiation Hardness Assurance Beyond Total Dose: Evaluating Single Event Effects, Braden Oh, Celvi Lisy, Gia-Uyen Tran, Whitney Lohmeyer, Michael Campola, Scott Palo
Small Satellite Conference
Radiation poses known and serious risks to smallsat survivability and mission duration, with effects falling into two categories: long-term total ionizing dose (TID) and instantaneous single event effects (SEE). Although literature exists on the topic of addressing TID in smallsats, few resources exist for addressing SEEs. Many varieties of SEEs exist, such as bit upsets and latch ups, which can occur in any electronic component containing active semiconductors (such as transistors). SEE consequences range from benign to destructive, so mission reliability can be enhanced by implementing fault protection strategies based on predicted SEE rates. Unfortunately, SEE rates are most reliably …

The attitude determination and control system (ADCS) for a satellite is responsible for multiple key roles in a satellite’s mission, including detumbling the satellite after deployment, pointing payload sensors, and orienting antennas and solar panels for effective communication and power generation. Designing an effective ADCS is crucial to a mission’s success; however, current methods often rely on actuators and sensors that are bulky and expensive, such as reaction wheels and star trackers. While these systems can provide high accuracy, they often cannot be used on CubeSats due to volume, weight, and cost restrictions.
This work builds upon PyCubed, a radiation-tolerant …

In this paper, we present a fully functional cubic sensor node prototype designed to be ballistically deployed from a rover or lander to regions of interest that might be unsafe or impractical for rovers or landers to reach. Unlike helicopters or drones, this system can be deployed in airless environments. Crucially, the nodes are equipped with wireless ranging and wireless communications capabilities, such that each node can be localized by leveraging wireless ranging with triangulation, and a cluster of deployed nodes form an expandable WSN (Wireless Sensor Network), that we term LunarWSN. The hardware redundancy of the network can reduce …

The Multiview Onboard Computational Imager (MOCI) built by the University of Georgia’s Small Satellite Research Lab (SSRL) will be one of the first small satellites to include a small form factor graphics processing unit (GPU), the NVIDIA TX2i, in its design and therefore includes three onboard computers that will need to coordinate and interchange data to successfully complete the mission. The Onboard Computer (OBC), standard for most satellite systems, will coordinate most system controls. The GPU serves as the onboard payload manager and bulk data processor and coordinates with the attitude determination and control system (ADCS) to collect all necessary …

This paper analyzes the various problems high school CubeSat organizations face, as well as their potential solutions. We conducted a case study of various high school CubeSat organizations from around the United States, interviewing them about their mission goals, organizational structure, funding sources, and other relevant information. We found that the three most common significant problems faced by these CubeSat teams were a lack of student training, turnover, and time commitment constraints. By comparison, a lack of funding and access to mentors were not expressed as the most significant problems for any of the groups. Teams shared their solution to …
