No specialized background is needed to absorb the material in this book. Instead of using rocket fuel, which is expensive, heavy, and often toxic, this technique allows spacecraft to change their orbits by pushing against Earth's magnetic field. The ACS uses the spacecraft computer to perform closed loop attitude determination and control. This is otherwise termed as ADAC, ADC or ACS. The NIC is the interfaces between the spacecraft's flight software, attitude determination, and its control subsystems and sensors. Attitude determination and control. - Active 3-axis control via magnetorquers. Using the Earth's magnetic field as a reaction field in attitude determination and control of earth orbiting satellites was first proposed early on in space science applications history. ANTELSAT Brochure http://iie.fing.edu.uy/investigacion/grupos/lai/files/ ANTELSAT_brochure_2012W01.pdf. A spacecraft system comprises various subsystems, dependent upon mission profile. ANTELSAT is a 2U CubeSat class satellite with a 70 cm SSTV downlink and amateur radio AX.25 Digipeater that is planning a Yasny Dnepr launch in 2013. Such a spacecraft would have to carry little, if any propellant, . We need to research on federal filter theory and application more, for ensure that the spacecraft mission successful completed, and for improve the accuracy and the reliability of spacecraft attitude control system. Attitude control: - Attitude determination via magnetometer and photodetectors. One appendix covers spacecraft attitude and orbit determination and control, and a second appendix describes operational scenarios supported by agent interactions.
