SBUDNIC

Additional information SBUDNIC

SBUDNIC is a group of Brown University students developing a cube satellite for launch using only terrestrial parts like Arduino Uno. We plan to make all of our designs open-source. SBUDNIC emerged from Professor Rick Fleeter?s ?Design of Space Systems? class, ENGN1760.\r\nWe aspire to be one of the fastest sketch-to-launch developments of a 3U cubesat. Period. SBUDNIC?s total budget is approximately $10,000 USD; we are working to meet our aggressive timeline by utilizing as many terrestrial components as possible.\r\nOur mission is to construct and launch a small satellite for amateur radio experimentation in satellite communications and control. Using low cost and widely available parts and very simple low bandwidth communications architecture, the spacecraft telemetry and downlinked photos can be easily received by any amateur or short wave listener with a minimum of cost and technical expertise. Hams can experiment with uplinking commands to the satellite to take a picture with one of the on-board cameras, immediately or with some time delay, and then to specify when (and thus where) that image will be downlinked. \r\nThe spacecraft itself is built using all commercially available amateur equipment at a cost and complexity compatible with club activities at a community level. The satellite can be built by a team with very limited prior experience in the satellite design or construction. The satellite will have an on-board camera and be able to receive a picture request from any capable ground station. This request can be to immediately take a picture and downlink it or to take a picture and transmit it at regular intervals or after a certain delay. The frequency of telemetry and image transmissions will be dependent on the power considerations of the satellite. This project is being used as an opportunity to teach ourselves and others about satellite design and construction with the aim of bringing the ability to build and operate a satellite within reach of individual community level amateur radio club organizations. \r\nOur design and construction process will be public information, so as to serve as a model for future low budget amateur satellite projects. We are using an Arduino processor and Arduino shield for communication, which will help to improve accessibility of the project to amateur ground stations, if they want to participate in the project.
