Electric Power Subsystem Design,cecraft. Electric Power is also often underestimated, resulting in insufficient power to support the “mission creep” requirements of the spacecraft. The EPS design procedure is outlined below. Each of the steps will be discussed and illustrated in more detail later.

Spacecraft Digital Hardware,he size of their memories. Thus, these are no longer major factors in the selection process. However, radiation hardness, sensitivity to SEU, power consumption and I/O capabilities are still properties that influence the choice of digital processors. A list of factors that should be taken into consi

Attitude Determination and Control System (ADACS),on mistake is to call for more stringent accuracy than is required by the payload. For example, if the mission is to simply scan the atmospheric spectrum from the Northern Hemisphere, then pointing much more than 5° is hardly required. Specifying pointing accuracy 1 or 2 orders of magnitude better r

Integration and Test,then performing thermal, vibration and thermal vacuum tests. After that, the spacecraft is ready to be shipped to the launch site, where it is functionally retested to ensure that no damage was done to the spacecraft. Then, the spacecraft is integrated with the launch vehicle.

Low Cost Design and Development,te a section on the practices used to come up with a very capable and complex spacecraft at a very low cost. The schedule (from contract award to launch) took one day less than one year. In reviewing that chapter now, after having developed 34 spacecraft, I must say that each procedure for keeping c
