摘要： An apparatus and method for simulating atmospheric scintillation includes a scintillation disk and a motor for rotating the disk at a substantially high speed. The disk has a dense varied pattern of substantially small closely spaced holes. The holes have different sizes and are arranged with a spatial distribution that is gaussian in amplitude and poisson distributed in separation. The motor can spin the disk to produce desired temporal variations as energy from the energy source passes through the holes of the disk.

摘要： An emulation system includes a central time source generating a time reference and an emulated spacecraft control processor which contains an embedded processor that provides an emulated input/output interface to communicate simulated spacecraft data. The embedded processor processes the simulated spacecraft data and contains a real time clock engine having a real-time clock period. The system further has a first simulation that processes attitude control system data from the emulated spacecraft control processor to simulate an attitude control system of the spacecraft in real-time. The first simulation engine operative to produce sensor data for input to the emulated spacecraft control processor based on the simulated system dynamics and adjusts the real time clock period in response to the time reference.

摘要： A system for testing an embedded control processor for a spacecraft comprises an Emulated Spacecraft Control Processor (24) which contains the embedded processor (26), a simulation engine (12), and a host computer (14). The Emulated Spacecraft Control Processor (24), executing embedded application software, provides an emulated input/output interface for the embedded processor (26) to communicate simulated sensor data, command data, actuator command data, and telemetry data to the simulation engine (12) and the host computer (14). The Emulated Spacecraft Control Processor (24) processes the simulated sensor data and the command data to form the actuator command data and the telemetry data. The simulation engine (12) processes the actuator command data from the Emulated Spacecraft Control Processor (24) to simulate the system dynamics of the spacecraft in real-time, and to thereby produce the simulated sensor data. The host computer (14) provides the command data and receives the telemetry data from the Emulated Spacecraft Control Processor (24).

摘要： A spacecraft emulation system that can emulate both the attitude control subsystem and the non-attitude control subsystem is integrated into a single compact unit. The unit includes an emulated spacecraft control processor for processing attitude control information and an emulated central command and telemetry unit for interfacing simulated spacecraft data. The inlet also includes a first simulation engine that is operative to simulate the spacecraft attitude control system and a second simulation engine that is operative to simulate the spacecraft power, thermal, propulsion and payload subsystems. Both the first and second simulation engines are connected to the emulated spacecraft control processor via a respective bus. A host computer provides the command data and receives the telemetry data from the emulated spacecraft control processor.
