DIY Space Watch: Scientist Builds Low-Cost Automated Observatory for Satellite Tracking

A computer scientist at Sandia National Laboratories, Allen Schnibben, has developed an innovative, low-cost automated observatory named SOHBRIT, using readily available commercial off-the-shelf (COTS) technology to track satellites. This breakthrough allows for continuous monitoring of the ever-increasing number of objects orbiting Earth, offering a more accessible and efficient way to manage space traffic and prevent potential collisions. The system runs on automated tasks, significantly reducing the need for constant human oversight. This development comes at a crucial time as Low Earth Orbit (LEO) becomes increasingly crowded with thousands of new satellites from mega-constellations and a growing amount of space debris. Traditional satellite tracking systems are often expensive and complex, but Schnibben's SOHBRIT demonstrates that effective Space Situational Awareness (SSA) can be achieved with more affordable components. Commercial entities like LeoLabs are also expanding ground-based radar networks for persistent orbital intelligence, highlighting the rising demand for comprehensive satellite monitoring. Looking ahead, the success of projects like SOHBRIT could pave the way for wider adoption of low-cost SSA solutions, empowering more nations, organizations, and even amateur enthusiasts to contribute to space safety. This shift toward accessible technology is vital for the sustainable use of space, ensuring that critical satellite services, from communication to navigation, remain uninterrupted by orbital hazards. The ability to monitor orbital traffic simply and effectively will be key to managing humanity's expanding presence in space.
