The US Space Force has finally taken ownership of the next-generation GPS control system, yet the project continues to face significant challenges. Despite a budget that has swelled to $8 billion, testing has revealed extensive issues across all subsystems. While M-code signals designed for military use were supposed to be fully exploited with OCX, ongoing problems mean the ground segment remains non-operational.

The delays have forced the military to rely on an ageing legacy system and delayed the full operational capabilities of GPS III satellites. This has heightened concerns about spoofing and jamming, particularly in conflict zones like Ukraine and the Middle East. The Space Force is now considering scrapping the program entirely or continuing with risky updates.

The saga highlights systemic issues in software development for critical military systems, which could have broader implications for technological advancements in defence. Ainsworth acknowledges: 'We are still considering how to ensure we move forward.' For now, the future of GPS control hangs on unresolved technical and management challenges.
