As President of PSS, Mr. Paluszek is responsible for company management. He is working with Sam Cohen of PPPL on a fusion engine for solar system missions. He is leading a project to develop a new optical navigation sensor for geosynchronous and deep space spacecraft. He is managing the Two Stage to Orbit Launch Vehicle project which employs horizontal take-off and landing and uses an aircraft first stage combined cycle engine.
He designed the Attitude Control System and ACS flight software for the OSC Indostar-1 satellite, which has been flying since 1997 and led the effort to develop the TDRS momentum management system for Hughes. Mr. Paluszek has developed commercial software products including the Spacecraft Control Toolbox, used worldwide for spacecraft simulation, analysis and control system design. He also developed the newly released Wind Turbine Control Toolbox for Matlab.
Prior to founding PSS in 1992, Mr. Paluszek was an engineer at GE Astro Space in East Windsor NJ. At GE, he designed the GGS Polar despun platform control system and led the design of the GPS IIR attitude control system and the Inmarsat-3 attitude control systems. The GGS Polar despun platform controller included active stabilization of the four deployed wire antennas using the despun platform motor. This was the one of the first applications of active vibration control on a satellite at GE. He also managed the ACS analysis unit and was lead attitude analysis on over a dozen satellite launches and shift supervisor, with responsibility for all subsystems, on one launch. This included flying over 100 satellite maneuvers.
As Vice President of PSS, Ms. Thomas helps manage the company in addition to performing and managing technical work on our government contracts.
Ms. Thomas has been the PI for several Air Force SBIRs developing automated decision systems for space defensive counterspace operations and has recently led consulting work analyzing a precision CubeSat attitude control system. She manages the Solar Sail Module for SCT (MATLAB) for high-fidelity simulation of sailcraft control systems and has developed tools for analyzing flexible sail models. She has developed collision monitoring tools for the safe guidance mode of the Swedish Space Corporation's PRISMA mission and TechSat 21. Ms. Thomas was the PI for the Phase I NASA SBIR, "Comprehensive Solar Sail Simulation" (2006), a Phase II Air Force SBIR, "Autonomous Satellite Servicing to Increase Effective Mission Life", studying the proximity operations of escort satellites (2003), and on the Phase I NASA SBIR, "Integrated Multi-Range Rendezvous Control System" (2003).
Prior to joining the technical staff full-time in February of 2001, Ms. Thomas worked at PSS in a series of internships since 1996. She has worked on a variety of software, including: artificial intelligence tools, an orbit propagation toolbox, Java web services, and a multibody simulation of the TDRS spacecraft for momentum management verification.
As a Master's student at MIT, Ms. Thomas worked on the design of a Shuttle flight experiment to study the plumes of a Hall and a pulsed plasma thruster, known as ETEEV (Electric Thruster Environmental Effects Verification). This effort included experimental work in MIT's new vacuum facility. The design studies included analysis of a number of plasma diagnostics.
Mr. Mueller has served as principal investigator for several projects at PSS. Under SBIR contracts for both the Air Force and Missile Defense Agency, he designed optimal guidance and control methods for high altitude airships. In 2005, he developed a decentralized system for formation flying guidance and control for NASA Goddard. Building on these methods, he developed the Formation Flying Module of SCT and designed the safe guidance mode for the PRISMA mission. In support of PSS' defensive counterspace efforts, Mr. Mueller has helped design new methods for rapidly evaluating the vulnerability of space assets, and for robust onboard planning of evasive maneuvers. Since 2009, Mr. Mueller has served as the PI for a Navy SBIR, now in Phase II.5, developing the SPEAR decision support tool: Satellite Planner for Execution and Reconfiguration.
Before joining PSS in August of 2000, Mr. Mueller completed his masters degree in the field of robust optimal control. He has research experience in H-infinity optimal control, mu-synthesis, and multivariable, gain-scheduled control using linear parameter-varying (LPV) techniques. For his masters thesis, he developed LPV controllers for flight-testing on NASA's F/A-18 System Research Aircraft. He has recently returned to the University of Minnesota and is now working towards a doctorate degree in aerospace engineering, with a research focus on optimal trajectory planning for stratospheric airships.
