Officials from Air Force Space Command’s Space and Missile Systems Center’s GPS Wing have announced the release of a request for proposal (RFP) for Phase B of the Next Generation GPS Control Segment (OCX) contracts.

OCX will replace the current Operational Control Segment managed from Schriever Air Force Base, Colorado, maintaining backward compatibility with the Block IIR and IIR-M constellation and enabling new modernized capabilities onboard the Block IIR-M and IIF satellites. In addition, OCX will provide command and control (C2) of new capabilities associated with the new GPS III generation of satellites.

The Phase B contract for OCX will include development of OCX Blocks 1.0 and 2.0. Block 1.0 will replace the existing legacy GPS command and control system and support mission operations of GPS IIIA satellites. Block 2.0 will support monitoring and controlling of the new L2C, L5, and M-Code signals as well as launch of both GPS II and GPS III satellites. This contract will also include options for interim contractor support, transition support, special studies, and sustainment for up to five years.

Northrop Grumman and Raytheon are currently performing technology development efforts under the Phase A OCX contract, which extends until September 2009. Work done on this Phase A contract provides input to the selection for Phase B.
