Abstract: Spacecraft transfer orbit operations include separating a spacecraft from a launch vehicle, while in a launch vehicle transfer orbit. The spacecraft includes a propulsion subsystem and a spacecraft controller that controls the spacecraft in a three-axis stabilized mode. With the spacecraft continuously in the three-axis stabilized mode, one or more orbit raising maneuvers are performed by firing either or both of a chemical thruster and an electric thruster firing. Any two consecutive orbit raising maneuvers are separated by a respective intervening coast period. While in the three-axis stabilized mode, the spacecraft does not rotate about any axis at a rate greater than 0.1 degree/sec and dumping of momentum stored in a reaction wheel system is avoided.

Abstract: An RFID cabinet for monitoring items having an RFID tag includes a cabinet having at least one locking front door. An RFID detector is used for monitoring each item placed within the cabinet and is located within the interior of the cabinet. A computer is coupled to the RFID cabinet and controls opening and closing of the front door and is configured to receive an input that identifies the user. In this way, the computer is configured to periodically record data read from the RFID tags by the RFID detector.

Abstract: A method for supplying items to dispensing units that hold at least one type of item and a record of inventory levels comprises periodically sending restocking information from the dispensing units over a network to a server computer. Ordering information is generated for the items to be restocked based on the restocking information. The ordering information is electronically sent to one or more supplier computers to order items to be restocked into the dispensing units.

Abstract: An automated reading system for associating an RFID tag and product information includes a conveyor belt for moving a product having an RFID tag and a bar code. The system also includes an RFID scanner and a bar code scanner for reading information on the product as it travels down the conveyor belt. A collecting device is used for receiving the product, and a computer having a database is used for recording the association between the RFID tag and the product information.

Abstract: A spacecraft having a body, one or more appendages coupled thereto, and a controller that implements methods that rotate the one or more flexible appendages to point it (them) towards the Sun to reduce spacecraft attitude pointing disturbances and improves spacecraft attitude pointing. The steps of the one or more appendages are timed to deadbeat the disturbance imparted to the spacecraft body. Timing of the appendage steps may be such that the periodic disturbances are phased to substantially cancel each other, or phased to decrease the magnitude of the net disturbance. The present invention also cancels solar array slew disturbances. The present invention cancels predictable disturbance torques before they produce a pointing error, improving the spacecraft pointing performance.

Abstract: An onboard star tracking system is used to provide continuous attitude data based on a fixed star catalog. An orbital position reference for the sensed star data is estimated from uploaded data. The attitude is calculated based solely on the star sensor data referenced to the estimated orbital position and compared to mission attitude to generate an attitude adjustment.
