Imagine you could test a high-tech satellite without launching a full-sized one into orbit on its own. That’s exactly what the NanoRacks-GOMX-3 experiment did. Conducted aboard the International Space Station (ISS), GOMX-3 was a miniature satellite—called a CubeSat—developed by Danish company Gomspace. It was designed to test how new radio communication technologies perform in low-Earth orbit.
The goal was simple but powerful: explore how to improve the way satellites send and receive data. That might sound like a small task, but think about the last time you used GPS or relied on satellite communication. These systems depend on efficient, accurate, and reliable radio links.
GOMX-3 featured a Software Defined Radio (SDR), which means it could change how it communicated by modifying software—no need to rebuild hardware. This flexibility is ideal for adapting to new missions or unexpected conditions in space. The satellite also carried systems to monitor the signal environment around it and assess Earth’s atmospheric characteristics.
Once deployed from the ISS, GOMX-3’s mission was to evaluate its SDR's capability to receive and decode signals, even when they came from fast-moving or weak sources. This is critical because satellites often experience variable conditions that affect signal strength.
By collecting and analyzing data in orbit, GOMX-3 gave researchers insights into what kind of tech works best for future missions. Whether it’s boosting data speeds or improving coordination between multiple satellites, GOMX-3 contributed a vital piece of the communications puzzle.
