System design has a goal that it be usable over 75% of the orbit by\n>an AO-13 or AO-40 capable ground station.\n> * A SSB/CW (etc.) transponder with uplink on L-band and downlink on\n>S1-band (2.4 Ghz). An AO-13 or AO-40 capable ground station will be able to\n>use this payload.\n> * A low rate text message system, like SMS. It will operate on \n>U/V-bands\n>and be usable over 75% of the orbit by a small terminal on the ground.\n> * These transponders will be implemented using Software Defined\n>Transponders (SDX).\n>\n>Eagle will also carry an advanced communications payload (ACP). Using\n>advanced signal processing and RF techniques, the ACP will allow:\n>\n> * Voice communications on S2-band (3.4 Ghz) uplink and C-band (5.8 \n>Ghz)\n>downlink using a single 60cm dish. The satellite antennas will be\n>electrically steered to reduce spin modulation and allow use over 75% of \n>the\n>orbit.\n> * An additional, fix-pointed, uplink will be available at L-band. This\n>L-band uplink will require a separate uplink antenna at the ground station.\n> * High rate data communications, such as streaming video, using a 2m\n>dish on S2/C bands.\n> * AMSAT will develop and make available an affordable ground segment \n>for\n>the ACP System.\n>\n>Additional information will be posted here in the near future.\n>\n>_______________________________________________\n>Sent via [email protected].
