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 …

Let’S Give The Fsck Up On Secded, Heather M. Quinn, Andrew Pineda, Gary Swift

Small Satellite Conference

Many space systems use error correcting codes (ECC) for handling radiation-induced upsets in memories. The most used ECCs are Hamming and Hsaio, which are single-error correction/double-error detection (SECDED) codes. The widespread use of these codes can lead to a dangerous overestimation of system reliability. Instead these codes are one of the best documented methods for microprocessor-based system crashes, due to uncorrectable faults. Less well documented is how these codes can lead to silent data corruption caused by miscorrections, where multiple errors are detected as a single error and corrected erroneously.

ECCs have always been sensitive to time-dependent errors, where SEUs …

Design And Qualification Of A Compact, Deployable Dual-Monopole Antenna System For Remote Sensing Microsatellites, Alexander J. Murphy, Bryan Johnston-Lemke, Robert E. Zee

Small Satellite Conference

Spacecraft conducting signals intelligence (SIGINT) missions require highly capable radio-frequency (RF) payloads. While the larger 80 kg-class platforms offer increased payload capacities, strict internal volume limitations persist. These constraints sometimes require stowing instruments, such as the dual-monopole Very High Frequency (VHF) antenna presented in this work, directly beneath the solar wings. This requirement has imposed a strict height constraint on the VHF antenna, mandating a highly compact and reliable deployment mechanism that avoids snagging or jamming during deployment. 

This paper presents the mechanism design and qualification test plan of a novel, deployable dual-monopole VHF antenna system designed to increase satellite …

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 …

The Genesis Of The Annual Usu Conference On Small Satellites, Rex Ridenoure, Alex Da Silva Curiel, Martin Sweeting

Small Satellite Conference

Reliance on fossil fuels, combined with the physical limits of ground-based solar arrays, makes a strong case for collecting solar energy in orbit. Earth intercepts roughly 1.4 kW/m² at the top of the atmosphere, but absorption by carbon dioxide and water vapour and atmospheric scattering cut peak surface intensity to about 1.1 kW/m², this results in an over a 20% reduction. While inclination, time of day, and weather restrict that to a narrow band of land for a few hours each day.

Advanced Ai Deployment On Smallsats: A Mixed Precision Approach To Onboard Perception And Fpga-Gated Inference, Margaret Michelsen, Jackson Gardner, Shawn Jones, Jackson Kulik, Mario Harper

Small Satellite Conference

MOTIVATION:

SmallSats are asked to make time-sensitive calls (vessel detection, cloud filtering, debris tracking) but CubeSat-class compute is starved for power, memory, and radiation-tolerant silicon.

Most missions still downlink raw imagery for ground processing, costing hours-to-days of latency and scarce bandwidth. Running inference onboard means solving two separate problems:

• When to run inference: compute and power budgets can’t tolerate a neural network firing on every frame.
• Whether it fits when it does run: the model has to live inside a memory and compute envelope measured in megabytes, not gigabytes.

Characterizing Rolling-Shutter Distortions In A 1u Cubesat Camera Using Led Strobe Imaging, Sharon Chan, Arseniy Dolgov, Andrea Schildhorn, Jenny Zhu, David Michelson

Small Satellite Conference

The ArduCAM OV5642 rolling shutter sensor was selected for ALEASAT because its simpler design results in reduced cost, power consumption, and heat generation. Although rolling shutter readout can introduce image skew due to the relative motion between the CubeSat and Earth, these sensors provide sufficient resolution and sensitivity within mission constraints. The feasibility of de-skewing, therefore, depends on the stability and predictability of the rolling shutter readout. Camera testing is not currently included in ISO 19683 (Space Systems – Design qualification and acceptance tests of small spacecraft and units). This work could be a step towards addressing that omission.

Development Of A Design Tool For 3d-Printable Cold Gas Thruster Systems For Nanosatellite Missions, Mikolaj Szyszka, Katherine Smith

Small Satellite Conference

Currently, there are 5219 Nanosatellites and CubeSats in orbit [1]. A decade ago, this number was only 800 [1], with forecasts predicting a total of 14,000 small satellites in orbit by 2033 [2]. However, out of the ones that are currently operational, only about 5% are equipped with a propulsion system. Omitting the electric and classified thrusters, cold gas systems are the most popular due to their simplicity and ease of operation. This shows a general lack of manoeuvrability and agility within small satellites in orbit. The proposed C.O.N.E tool aims to bridge the gap between nanosatellite manufacturers and simple …
