Coconut CubeSat Amateur Radio Information
Overview
Coconut is a 1U CubeSat developed by the Sun Devil Satellite Laboratory at Arizona State University. It is expected to be launched to the ISS on the Cygnus NG-24 ISS resupply mission. The primary mission of Coconut is to provide a digipeater service for amateurs using inexpensive, low-powered LoRa Modules. This will allow students at ASU and other amateur radio users to interact using inexpensive ground nodes. Coconut is being built 100% by students. It is a proof of concept that demonstrates the capabilities of students to build their own CubeSat. In addition, we will host a store and forward experiment, whereby amateurs can register on our project website, and then have data that they uplink, again using LoRa, captured at our ground station, and then forwarded by means of their choice to the specified recipient. The mission is oriented to students to engage in hands-on learning and experience with spacecraft hardware and radio transmission. It will also allow hams worldwide to utilize a standard digipeater function for the entire lifetime of the satellite, as well as give them the opportunity to participate in a store-and-forward experiment.
