U.S. Pentagon drops OCX GPS ground control programme after 16 years

The U.S. Defense Department has formally halted OCX, a next-generation ground control system for the U.S. military’s GPS satellite network, after years of technical problems and cost and schedule overruns. The programme, awarded in 2010 to Raytheon, now RTX, was initially expected to cost $3.7 billion and finish in 2016, but government spending rose to about $6.27 billion and total completion was estimated near $8 billion. The U.S. Space Force will instead upgrade the existing GPS control system.
