Specializing in infrared physics, she became manager of the optics department at the Rockwell International corporation, then a senior engineer at Honeywell and at the Jet Propulsion Laboratory (JPL). At the JPL, she designed, developed and implemented a novel system for autonomous optical navigation using star charts and an intelligent CCD-based camera. This system is the basis for autonomous navigation in all commercial aircraft, in satellites forming the GPS network, and others. The autonomous navigation system was used to facilitate navigation of the NASA 's Cassini–Huygens probe to Saturn in 2005. Strojnik Scholl received several NASA Certificates for creative development and technological innovations
