Our team is currently putting together a Hardware-in-the-loop test platform with the same hardware from our partner NanoAvionics and our in-house developed hardware we want to put into the satellite. It is important to test, test, test, and fail, and test, test, test, and fail…did I mention test and fail? when you’re building CubeSats. The most common issue facing CubeSat teams is the lack of time to perform good integration tests early enough to uncover design errors and interface mismatching. Having Hardware-in-the-loop setups helps us perform the integration tests early, and to mimic the setup we will have on HYPSO.
