The Pentagon has canceled a ground control system for the US military's GPS satellite navigation network after the program's enduring problems "proved insurmountable," the US Space Force announced in a press release Monday.
The Global Positioning System Next-Generation Operational Control System, known by the acronym OCX, was officially canceled by Michael Duffey, the Pentagon's defense acquisition executive, on Friday, April 17, the Space Force said.
The decision to terminate the OCX program ends a 16-year, multibillion-dollar effort to design, test, and deliver a command and control system for the military's constellation of GPS navigation satellites. The program consisted of software to handle new signals from the latest generation of GPS satellites, GPS III, which started launching in 2018, along with two master control stations and modifications to ground monitoring stations around the world.
