Multi-purpose Active Pixel Sensor (APS) - Based Microtracker
A new, photon-sensitive, imaging array, the active pixel sensor (APS) has emerged as a competitor to the CCD imager for use in star and target trackers.

Flow Calibration
Flow Technology Inc. worked with Lewis Research Center to develop a system for monitoring two different propellants being supplied to a spacecraft rocket thruster. They then commercialized the technology in the Microtrack, an extremely precise low-flow calibration system. Moog Inc., one of the device's primary users, measures the flow rate or the speed at which hydraulic oil flows through pin sized holes in disc shaped sapphires with the Microtrack. Using this data, two orifices with exactly the same flow rate can be matched as a pair and used as masters in servovalve production. The microtrack can also be used to calibrate other equipment.
