The ground control system (OCX) that Raytheon is developing for the next-generation GPS program has passed a Pentagon review, reports Reuters. The program will be monitored to ensure it stays on track, a senior Air Force official said on Feb. 6 as reported by the news service.
Major General Roger Teague, director of space programs for the Air Force acquisition chief, said a review by chief arms buyer Frank Kendall went well, but program officials and the contractor got “tough marching orders” to stick to schedule and cost targets.
Raytheon’s program manager Matt Gilligan said the review provided the company with “clear direction, the best technology, and appropriate resources to…deliver OCX on a schedule that meets GPS enterprise needs.”
Kendall had ordered the review after an Air Force restructuring that increased the cost of the program by 80 percent to $1.6 billion.
