17. 17 Key Field Terminal Performance Requirements Key performance requirements govern the attributes of the aperture, RF front-end and demodulator “Processing” requirements (e.g., decoding) can be viewed as “functional” requirements LRD aperture requirements: 1-meter diameter Aperture/RF front-end requirements: G/T, passband amplitude and phase response (components of implementation loss) RF front-end/demodulator requirements: Implementation loss (covering passband response, phase noise, demodulator performance with respect to theory, et al) Link budget entries serve as starting points for these requirement values Requirements are not independent, trade-offs exist

24. 24 What is NPOESS planning? NPOESS responsible for building software and terminal specifications, but not for building terminals NPOESS to publish specifications and design trade information NPOESS DPE software available on the program website for download NPOESS to deliver data to users world-wide in accordance with U.S. National data policy Mission data downlinked around the world at no cost to receivers Data encryption/data denial capability exists for U.S. National defense -Denial can be done on a world-wide or geographic basis
