Patent number: 10811143Abstract: The invention is for a startup system for nuclear fusion engines in space. The combustion of hydrogen and oxygen produces heat that is used by a heat engine to produce electricity. This can be supplemented by electricity from other operating engines. The exhaust from the combustion is condensed and electrolyzed to produce hydrogen and oxygen once the engine is in operation. This provides a constant source of energy for future startups. The engine is started up at partial power in electricity generation mode and this power replaces the power from the combustion as it grows. The combustor uses the same heat engine as the nuclear engine uses for power generation.Type: GrantFiled: January 17, 2019Date of Patent: October 20, 2020Assignee: PRINCETON SATELLITE SYSTEMS, INC.Inventors: Michael A. Paluszek, Eric M. Ham, Yosef Razin, Samuel A. Cohen

Patent number: 10752385Abstract: A dipole cancellation system and method may include a plurality of magnetometers for measuring a device magnetic field associated with a plurality of device coils generating a device magnetic field having a primary magnetic dipole moment. A compensating coil carrying a compensating current running a first direction that generates a compensating magnetic field having a compensating magnetic dipole moment. The compensating coil may be positioned and the first current may be selected so that the compensating magnetic dipole moment completely cancels the primary magnetic dipole moment. A method may use the system to stabilize a spacecraft by calculating an estimated torque of the spacecraft, receiving a value for an external magnetic field, receiving a value for a device magnetic field, and calculating and applying a compensating current may be then applied to the compensating coil to cancel the primary magnetic dipole moment, wherein the spacecraft is stabilized.Type: GrantFiled: March 9, 2018Date of Patent: August 25, 2020Assignee: PRINCETON SATELLITE SYSTEMS, INC.Inventors: Stephanie Thomas, Michael A.

Publication number: 20090132105Abstract: Provided is a method and system for maneuvering a first spacecraft relative to a nearby second spacecraft that occupies a finite volume of space including obstacles in the vicinity of the second from a measured present relative position to a desired ending relative position. A trajectory is computed for the first spacecraft from the present relative position to the ending relative position using the A* algorithm. One or more thrusters of the first spacecraft are then fired. The first spacecraft's relative position and velocity are then measured and compared to the computed trajectory.Type: ApplicationFiled: August 18, 2008Publication date: May 21, 2009Applicant: PRINCETON SATELLITE SYSTEMS, INC.Inventors: Michael P.
