5. __________ and __________ are the first steps in the design process and often the most critical to mission success.
6. This step is the final paper design and analysis that is done prior to ordering and acquisition of parts and components for the fabrication phase.
7. A detailed ___________- is required to properly assess the performance of the payload.

24. The most common ____________ frequencies are 915 MHz, 2.45 GHz, and 5.8 GHz, all of which are LOS frequencies.
25. Because GPS ____________ are caused by various effects such as passing through different layers of the earth’s atmosphere, correction signals are generated by stations at a known location to augment the original information and increase positional accuracy; the distortions may then be subtracted out.
