The mission must relate in some way to the\n> advancement and understanding of the technical\n> and operational aspects of radio and satellite systems and are relevant\n> to the amateur and amateur-satellite\n> services. This excludes more general science payloads within missions\n> like earth-observation, biology, wildlife\n> tracking, geology, etc. which should be operated under other\n> radiocommunication services because they are\n> not related to radio technique. Furthermore, any mission that proposes\n> any sort of pecuniary (monetary or\n> financial) return is specifically excluded from amateur and\n> amateur-satellite service bands.\n>\n> Radio technique means having a reasonable possibility of application to\n> radio communication systems\n> operated in the amateur satellite service. Missions that are classified\n> as amateur-educational might study\n> aspects within the following topics:\n> • Radiocommunication modulation methods and transmission protocols\n> • Attitude determination and control systems\n> • Command and control procedures\n> • Radio receivers, transmitters and transponders\n> • Satellite antennas systems\n> • Sensors to study spacecraft performance\n> • Power controls and supplies for use in space\n> • Spacecraft computers, memory, operating systems, programs and related\n> items\n> • Radiation effects on electronic components\n> • Radio wave propagation\n> • Meteor trail reflection and other sporadic propagation mechanisms\n> • Measurements of the orbital environment\n> • Solar panel technologies\n> • Software Defined Radios\n> • Radiation tolerant electronics\n> • In-orbit spacecraft software updates.\n>\n> Technology developed and information acquired by missions studying the\n> above topic have direct relevance\n> to the advancement of the amateur-satellite service.\n>\n> Satellite missions that are purely amateur include:\n> • Linear transponders or FM repeaters for voice or data communications\n> • Digital voice repeaters\n> • Transmission of images using appropriate analogue or digital standards\n> • Amateur Packet Reporting System (APRS) transmissions\n> • Microwave beacons\n> • Digital Store-and-forward bulletin boards and global messaging systems.\n>\n> Transmission of telemetry alone and without additional mission\n> components is generally an insufficient reason\n> for a mission to be considered for operation within frequency bands\n> allocated to the amateur-satellite service.\"\n>\n> 73,\n> Nico PA0DLO\n>\n>\n>\n> -----------------------------------------------------------\n>\n> Sent via AMSAT-BB(a)amsat.org.
