Helium-filled latex weather balloons have been utilized for many years to carry small satellite prototypes and subsystems into the stratosphere to allow testing in a “near space” (stratospheric) environment. A variety of environmental factors similar to the space environment can be found in this region, such as a rarified atmosphere, increased thermal stress including very low temperatures, increased solar radiation, the necessity of remote command and control, tracking, and telemetering of data. While this method of flight testing has been well-proven, a recent increase in the price of helium has driven the cost of such test programs to much higher …

This poster presents an overview of a tool that has been created to provide students with real-world experience in the design, development and operation of control and scientific mission software for a cyber-physical system. The ROOFSAT, developed at UND, is a low-cost analog for a small spacecraft (though in many ways these capabilities also enable similar UAV work). The ROOFSAT was constructed with approximately $1,500 generously provided by the John D. Odegard School of Aerospace Sciences out of commercially-available parts. It includes multiple cameras, a pan-tilt mount and the same space-qualified computer hardware which has been used on both spacecraft …
