The Next-Generation Global Positioning System — Ground Control Segment (GPS-OCX) has completed both its integrated baseline review and its system requirements review, Northrop Grumman Corp. [NOC] announced.

That integrated baseline review accomplishes several goals, such as identifying key schedule milestones, ensuring adequate resources are available to complete program tasks, and verifying tasks are planned and can be objectively measured.

The review follows close on the heels of the Northrop Grumman team’s successful system requirements review
