Raytheon’s global positioning system (GPS) advanced operational control system (OCX) has successfully completed software iteration 1.4 critical design review (iCDR), demonstrating its maturity and readiness to support launch missions of the US Air Force’s (USAF) GPS III satellites.
Software iteration 1.4 offers the initial GPS III command and control capability required to support the first three launch exercises, eventually leading to the launch and checkout of the first GPS III satellite vehicle.
Raytheon Intelligence and Information Systems business GPS OCX programme manager Ray Kolibaba said: ”OCX will usher in a new era in precision space-based navigation and timing, consolidating GPS satellite operations in a single, efficient and evolvable control system that is protected against current and future cyber threats."
The GPS OCX is an advanced operational gateway service developed through iterative software development process, which provides greater efficiency and flexibility in military satellite ground system development to address the changing needs of the programme.
Iteration 1.4 iCDR represents the first test of the new iterative CDR process and establishes that the company and USAF Space and Missile Systems Center have fully integrated this commercial best practice in purchase.
The GPS OCX is a next-generation system, designed to enhance the soldier’s situational awareness by providing secure, accurate and reliable navigation and timing information in the battlefield.
Integrated with built-in automation and compact service-oriented architecture, the GPS OCX offers command, control and mission management for the GPS constellation, including IIR-M, IIF, with improved defence against current and future cyber threats.
The cost-effective system allows for full navigation messaging on the new L2 and L5 civil signals and jam-resistant military signal (M-Code), in addition to supporting the new L1C civil signal on GPS III satellites, enabling interoperability with international global navigation satellite systems.
