Not wanting to disappoint our members, Jerry Buxton, N0JY, AMSAT VP- Engineering and his team are making plans for an informative and entertaining presence. No fewer than ten members of the engineering team will attending this year窶冱 Hamvention. Probably the most interesting exhibit will be a full-scale model of the GOLF-TEE (Technology Exploration Environment) satellite. The 3-D model printed by team member Tom Karnauskas, N0UW, gives an interesting look at the challenges that satellite designers face when trying to fit stacks of circuit boards, bundles of batteries, attitude sensing and control systems, and experimental payloads inside a 10cm x 10cm x 30cm spaceframe. The model also gives a look at the challenge of adding deployable solar panels to the exterior of the spacecraft. Given the fact that the GOLF program represents AMSAT窶冱 return to Highly Elliptical Orbit (HEO), engineers will no-doubt be busy answering questions on all facets of the GOLF program. Engineers will also be on hand to answer questions about the ongoing development of the Fox-Plus series of satellites. Recognizing the success of the original Fox series as an entry level introduction to amateur satellites, the engineers working the Fox-Plus birds are committed to improving on the original concept and setting the stage for future capabilities for these Low Earth Orbit (LEO) satellites. For those interested in a look even further into the future, engineers working the ASCENT program will also be present. ASCENT, meaning, Advanced Satellite Communication and Exploration of New Technology, is a 窶徭andbox窶� for future satellite communications and related systems to be explored and pursued for eventual flight use. A radiation-tolerant internal-housekeeping-unit (RT-IHU), software defined radio (SDR) methods, and a 10 GHz PA design ideas are some ASCENT projects that will fly on GOLF-TEE. Engineers at the table can also discuss other ASCENT projects in the works such as a slow-scan television (SSTV) payload, a packet repeater payload and propulsion systems suitable for CubeSat operation.
