Final 12 months, simply before the Fourth of July vacation, the US Space Force formally took possession of a brand new working system for the GPS navigation network, elevating hopes that certainly one of the army’s most troubled area packages may lastly bear fruit.
The GPS Subsequent-Era Operational Management System, or OCX, is designed for command and management of the army’s constellation of greater than 30 GPS satellites. It consists of software program to deal with new indicators and jam-resistant capabilities of the newest technology of GPS satellites, GPS III, which began launching in 2018. The bottom section additionally consists of two grasp management stations and upgrades to floor monitoring stations round the world, amongst different {hardware} components.
RTX Company, previously often called Raytheon, received a Pentagon contract in 2010 to develop and ship the management system. This system was supposed to be full in 2016 at a value of $3.7 billion. At the moment, the official value for the floor system for the GPS III satellites stands at $7.6 billion. RTX is growing an OCX augmentation projected to value greater than $400 million to assist a brand new collection of GPS IIIF satellites set to start launching subsequent 12 months, bringing the whole effort to $8 billion.
Though RTX delivered OCX to the House Pressure final July, the floor section stays nonoperational. 9 months later, the Pentagon could quickly name it quits on the program. Thomas Ainsworth, assistant secretary of the Air Pressure for area acquisition and integration, informed Congress final week that OCX is nonetheless struggling.
Hopes Dashed
The House Pressure’s formal acceptance of the floor system from RTX final 12 months marked a turning level for OCX after years of blunders. The handover allowed army groups to validate the new management software program and upgraded floor amenities before declaring the system prepared for operational service. However this testing uncovered extra issues.
“Consequently, in depth and extra operationally related testing with precise GPS satellites, floor antennas, and person tools led to a rise to find in depth system points throughout all subsystems, a lot of which have not been resolved,” Ainsworth informed the Home Subcommittee on Strategic Forces in ready testimony.
“For over 15 years, the program has skilled vital technical challenges, schedule slips, and related value progress, placing in danger the launch and functionality of future GPS satellites,” Ainsworth continued.
Delays in the OCX program compelled the army to retool the GPS community’s decades-old legacy management system to handle the GPS III satellites. Upgrades in 2020 allowed the House Pressure to start utilizing a subset of the new capabilities enabled by “M-code” GPS indicators designed for warfare.
The military-grade indicators are particularly necessary now to fight GPS jamming and spoofing round conflict zones in Ukraine and the Center East. M-code is extra resistant to jamming, and its encryption makes it tougher to spoof, a type of assault that makes receivers belief faux navigation indicators over actual ones. The improve additionally permits the army to deny an adversary entry to GPS throughout battle, whereas sustaining the capacity for US and allied forces to use M-code for a bonus.
Navy officers beforehand thought they wanted OCX up and working to absolutely exploit M-code indicators on roughly 700 varieties of weapons techniques corresponding to airplanes, ships, floor automobiles, and missiles.
Due to its civilian and army significance, the GPS community is an “enticing goal for adversaries,” mentioned Lieutenant Normal Doug Schiess, the House Pressure’s deputy chief of operations. “Jamming [denial of signal] and spoofing [false signals] are a present and rising risk to GPS. We are modernizing GPS to mitigate these threats.”
However a key a part of the modernization is nonetheless suffering from issues. Ainsworth informed lawmakers that persevering with to replace the current GPS floor management system “is now a viable choice as systemic points with OCX proceed.”
