Princeton Satellite Systems

Princeton Satellite Systems, Inc. is a small aerospace and energy technology company. It is based at 6 Market Street, Suite 926, in Plainsboro, New Jersey. The company says its focus on software lets it build solutions for many control problems quickly. The about page describes the career of Mr. Paluszek, including work at the Charles Stark Draper Laboratory and GE Astro Space, before the company was founded.

The company sells commercial software. Its Spacecraft Design Toolbox is used to design, analyze, and simulate spacecraft. It covers attitude and orbit control and estimation, subsystem tools for link, power, and thermal, and algorithm work in MATLAB. The Simulation Framework offers cross-platform C++ libraries for matrix and quaternion operations, plus simulation and control frameworks. A customer quoted on the site says the libraries saved it over a year of development time.

The site says the company serves aerospace primes, government agencies, and universities. It also describes contracts with the Navy, Army, and Air Force, NASA, the Department of Energy, the National Science Foundation, and ARPA-E.

Research areas listed on the site include the Direct Fusion Drive, also called Starfire, fusion propulsion, power electronics, a deep space transfer vehicle, biomechanics and orthopedic implants, and hypersonics. A news item says the BBC mentioned the Starfire fusion propulsion system.

The site lists past projects with dates. These include GPS IIR in 1997, TDRS H, J, and I in 2000 and 2002, PRISMA in 2010, NIAC Fusion in 2016, Navy MUOS in 2017, and ARPA-E projects in 2022 and 2023. A 2026 news item says a new U.S. patent was awarded for a mobile robotic arm used for momentum unloading and orbit control.

Recent news for 2026 includes a Toolbox release, an appearance at the El Alamein International Airshow, the AIAA ASCEND meeting, and a new book on advanced space propulsion.
