The Operational Control System (OCX) for GPS III is a next-generation system that will deliver improvements to dramatically increase the performance and effectiveness of the entire GPS system. OCX will replace the existing ground system that receives signals from the 31 GPS satellites already orbiting the earth. OCX will provide command, control, and mission support for all current and future GPS satellites.

L3Harris developed the technology for the key navigation components of the OCX, which consists of a Master Control Station (MCS), a backup MCS, dedicated monitor stations, and ground antennas. Innovative technology and on-schedule delivery keeps our presence first and foremost in the GPS marketplace.

• New anti-jamming technologies
• DODI 8500.2 Information Assurance Standards for Defense in Depth security
• Modern service-oriented architecture that integrates open system standards

The current GPS Control Segment is a global network of ground facilities that track the GPS satellites, monitor transmissions, perform analyses, and send commands and data to the constellation. L3Harris experience and successful performance on the space and user segments informs our work on the control segment. Our programs have included GPS Blocks I, II, IIA, IIR, IIR-M, and IIF.
