| Headline Details: This 4U mission supports both Amateur activity, and student experiments as follows: For amateur activity, the spacecraft will support digipeating with AX.25 protocol at 1200 baud on the UHF frequency assigned by IARU SatCoord, Also supported with the same radio, the student experiment with characterizing Very Low Frequency (VLF) emissions. It will measure VLF wave energy that originates from lightning and ground-based transmitters and propagates to the outer reaches of Earth's magnetic field (the magnetosphere). This is important for understanding the extent to which ground based electromagnetic sources can impact the near-Earth space environment. Additionally, operating the CANVAS CubeSat would open its mission to the amateur CubeSat community for any desired digipeating or to further prove, verify, and operate the space-rated S-Band system, UHF system, ADCS system, CDH system, and the FSW system once science requirements have been met. Many of the students working on CANVAS have little to no amateur radio exposure when they join the project. In working on the project, these students become knowledgeable and appreciative of the amateur radio art and go on to join the ranks of the next generation of radio amateurs. CANVAS also specifically studies the space weather environment, focusing on very low frequency waves. This research plays an important role in the growth of understanding the radio art, especially how VLF waves propagate and affect the space weather environment, which in turn affects amateur radio operation. Through operating the CANVAS CubeSat, students will be able to further verify and prove their VLF wave knowledge with real downloaded science data. To receive this science data, students will have to undergo many lessons on downlinking, downloading, and processing data for furthering the science mission. The amateur operators around the globe will be able to participate in the CANVAS mission by receiving satellite telemetry data during the time of downloading science data, then will be able utilize the UHF digipeater function after completion of the one-year science mission. Proposing a UHF downlink using 9k6 GMSK with AX25 packets and on S-Band using 5Mbps OQPSK with CCSDS packets. Planning a Minotaur IV launch from Vandenberg into a 500 km orbit with 50 degree inclination in February 2026. These satellites are also expected to be on the same launcher - STPSat-7, Rawhide, MISR-C, AggieSat6, MAMBO, Auris, MOCI, USNA16, and INCA-2. | ||||
