Bowshock I and II
The Bowshock I and II programs were funded by MDA to provide the predictive capability to design and deploy effective sensor systems for target acquisition and tracking in future atmospheric interceptor systems.
SDL developed the filtered photometers and the atomic oxygen sensors, performed the integration of these instruments and accompanying sensor packages, tested the instruments, and supported the flight campaigns.
Bowshock I and II launched in February 1991 and December 1995, respectively. These campaigns provided data needed to improve predictive capabilities in UV wavelengths by four orders of magnitude.
