Latest Patents
Adsit's latest patents include a "Pre-bias scheme for roll momentum unloads on pitch momentum bias/yaw reaction wheel spacecraft." This invention introduces an automatic, on-board system for orbiting spacecraft that effectively controls and reduces short-term transients caused by roll momentum unloads. By manipulating the states of the nutation damper, the system resets one of the states in the polynomial transfer function to a value proportional to the expected roll momentum unload. This innovative compensator automatically dampens the resulting transient, thereby reducing short-term transients without altering the spacecraft's roll bias.
Another significant patent is the "Control system and method for spacecraft attitude control." This invention describes position control methods for satellites and spacecraft, facilitating the transition from thruster control to momentum wheel control in a three-axis stabilized spacecraft. The method allows for a seamless transition from a high-bandwidth, high-torque thruster-controlled stationkeeping mode to a low bandwidth, low torque momentum wheel On-Orbit Mode. This unique threshold entry method initiates the transition at the most favorable dynamics, improving pointing performance and significantly shortening the time spent in the transition mode.
