As a graduate student at Purdue University, Frederick J. Doyle learned photogrammetry, the science of using photos and mathematical algorithms to accurately depict Earth's geometry. That was heady stuff, but maybe not as heady as triangulating through a time of unprecedented internal debate in America's ISR space community. UAVs have eclipsed the value of ISR satellites, plans for a new spy satellite constellation called the Future Imagery Architecture crumbled because of government and industry mismanagement, and for now at least, there will be no new Space Radar constellation or broad-area mapping constellation. In the wake of all that, U.S. officials now disagree over the sizes and types of satellites to build, who should manage them and who should own them. The success of airborne ISR in Iraq and Afghanistan has prompted the ultimate existential question for space ISR advocates: How much should America invest to replace its most "exquisite" satellites, the term Americans reserve for their most powerful imaging and eavesdropping satellites?
