Precision Navigation Systems: Challenges Remain with Fielding New Capabilities

The Department of Defense (DOD) is facing challenges in modernizing its Global Positioning System (GPS) due to delays. To address these issues, DOD is developing new complementary sources of positioning, navigation, and timing (PNT) data to mitigate GPS threats.

The Air Force is making progress in developing modernized GPS military code (M-code) receiver cards, but challenges remain with fielding and integration. The Navy is developing an interim solution for its aircraft to use M-code, while the Army and Navy are fielding M-code capable and multi-PNT receivers in ground vehicles, ships, and Army aircraft. The PNT Oversight Council, mandated by Congress, can make budget-related recommendations to the services, but the services are responsible for their own budgets.

Consolidating and aligning efforts among the services could improve synchronization of schedules and strategic alignment of funding. The military services are also pursuing integration of complementary PNT data into multi-PNT receivers. Despite these efforts, the PNT enterprise still faces challenges, including the need for more effective oversight and coordination among the services.
