Fast-tracking and Simplifying Second-gen Sun Sensor Redesign with Ansys Zemax OpticStudio Software

The Aquila D01 sun sensor from NewSpace Systems (NSS) is a proven and reliable system with extensive in-orbit heritage. It features a detector housed beneath a metal mask with precision-cut slits. As sunlight passes through these slits, it creates a unique one-dimensional brightness profile on the detector. This pattern is then analyzed to determine the sun's position. In 2022, the linear array used in the Aquila D01 was discontinued, prompting an effort to redesign the sun sensor to meet updated component availability.

Achieving Precision Through Early Optical Simulation

“Ansys Zemax OpticStudio software turned a complex redesign into a precise and efficient process, ensuring accuracy without unnecessary overhauls.”
