In-Orbit Demonstration Of Pbi Water Ion Thruster: Rapid Startup Capability For Small Satellite Missions, Yuichi Nakagawa, Kazuya Yaginuma

Small Satellite Conference

As small satellite constellations proliferate, the demand for safe, responsive propulsion systems has intensified to support agile orbital maneuvering. To address the lengthy startup downtimes of conventional systems, a 1U-class water-based ion thruster utilizing electron cyclotron resonance (ECR) plasma generation was developed. This thruster is characterized by a drastically minimized Time-to-Thrust (TTT), which maximizes the operational window for primary payload activities. Extensive ground testing established a robust baseline, demonstrating a 99.9% ignition success rate across 2,476 automated firing cycles with a highly reproducible median TTT of 73 seconds. Ground validations also confirmed an operational lifespan supporting a total impulse exceeding …

Development And Qualification Of A Cubesat Scale Hybrid Thruster For In-Orbit Demonstration, Sho Suzuki, Jeje Kudakwashe, Izumi Chimoto, Sheila Langa, Yasuhiro Fukumoto, Yuki Nobuhara, Shota Hirai, Landon Kamps

Small Satellite Conference

The growing demand for agile orbital maneuvering in small satellites highlights the need for propulsion systems that provide both sufficient ΔV and meaningful thrust. Existing options remain polarized between low‑thrust electric propulsion and hazardous, difficult‑to‑miniaturize chemical systems. Hybrid chemical propulsion offers a promising middle ground; however, only one in‑orbit demonstration has ever been conducted, leaving the technology at a low level of maturity. Letara Ltd. has developed ICR‑X, a 2U CubeSat‑class hybrid chemical propulsion system using HDPE fuel and nitrous oxide. The system features an integrated oxidizer‑tank–combustion‑chamber structure, a low‑power multi‑restart ECP ignition system, and oxidizer‑temperature‑based thrust control, enabling 1–4 …

Scaling Distributed Spacecraft Autonomy Operations With Simple Temporal Networks: Introducing Splinter, Michael Iatauro, Caleb Adams, Caroline Lassiter

Small Satellite Conference

The Absolute Time Sequence (ATS) is a well-established mechanism for high-level spacecraft control, executing commands at specific times. One weakness of ATSs is that the cost of making a change to the command sequence grows with the length of the sequence, and the cost paid is many repetitive-but-detailed changes to the timing of commands, which is error-prone.

This weakness becomes a liability when scaling up to spacecraft swarms or long ATS durations because any perturbation to the command sequence or schedule incurs significant cost. Fitting that cost within a small team or short sequence development timeline becomes a central challenge …

Music Hall Thruster For The Space Trajectory Demonstrator 1.0 Mission, George-Cristian Potrivitu, Matteo Laterza, Suryono Gunawan Ali, Justin Ong, Jian Wei Mark Lim, Nikolay Vedenkin

Small Satellite Conference

The MUSIC Hall thruster has been selected as the propulsion system for the Space Trajectory Demonstrator 1.0 mission. The propulsion system is based on four baseline MUSIC 4U systems with two Xe tanks and a planned total impulse of at least 150 kNs. The four thruster units can provide up to 12 mN of combined thrust and the system will be used for orbit raising. The satellite platform is a 50 kg-class microsatellite scheduled to launch in Q3 2027 with a KSLV-II launcher from the Republic of Korea. MUSIC STD 1.0 propulsion system follows an 18-month long development timeline with …

Small Satellite Conference

Vyom 2U is a compact 2U green monopropellant propulsion system designed to deliver a total impulse of 1700 Ns. At Beginning-of-Life (BOL) conditions, corresponding to a tank pressure of 24 bar, the thruster can deliver up to 1.1 N with a specific impulse of approximately 250 s, while requiring a peak electrical power of 15 W. At an operating pressure of 14 bar, the propulsion system delivers a thrust of approximately 0.67 N with a specific impulse of about 238 s. This operating point was deliberately selected for in-orbit operations to maintain sub-newton thrust levels compatible with the attitude control …
