Headline Details: A 2U CubeSat. OreSat has three missions: 1. The primary mission is "OreSat Live", an innovative space-based STEM outreach mission. The satellite will downlink live video directly from the satellite in low earth orbit to any group of Oregon students or amateur radio group ("operators") that builds an inexpensive, easy to assemble, simple to use, hand-held ground station. The operators request an OreSat Live "session", and the OreSat Operations Group schedules the next available satellite pass for them. During the pass, OreSat points at the station location in Oregon, and downlinks the video data. The operators use the handheld ground station to receive the video on their smartphones or laptops. The OreSat Live space segment is based on technology heritage of the DxWiFi project, a long distance IEEE 802.11b (WiFi) S band radio link run under FCC Part 97 ("amateur 802.11 b") pioneered at Portland State University. Although the Oregon Live handheld ground station does not require an amateur radio license to operate, it does teach radio principles and technologies. It specifically encourages operators to pursue their amateur radio licenses in order to utilize the radio systems on OreSat, which are a CW and AX.25 APRS UHF amateur radio beacon providing real time telemetry of the satellite. 2. The secondary mission is the"Cirrus Flux Cam (CFC)", an educational "citizen science" based optical instrument to study the global distribution of high-altitude cirrus clouds from low earth orbit. The CFC is a small, low power multi-spectral Short Wave Infrared (SWIR) and visible light camera system designed to image the optical flux of sunlight reflected off high-altitude (>15 km) cirrus clouds. 3 The tertiary mission is to provide flight heritage to the open source "OreSat bus", an open source card-cage based system that is ideally suited for large educational CubeSat projects involving interdisc rna teams of students. Proposing CW, APRS and G3RUH 9k6 packet downlinks on UHF and 1 Mb Spread spectrum DBPSK downlink on S Band. Planning an ElaNa deployment from the ISS in April 2021.
