Nathan Strout WASHINGTON — The fourth GPS III satellite has achieved operational acceptance from the U.S. Space Force at record speeds using an expedited process that was 10 days faster than previous efforts. “[The fourth GPS III satellite] sets a new standard for handover from the contractor launch team to operational acceptance, setting the satellite healthy to the global user community approximately 30 days post launch. Moving forward with future GPS III launches, the timeline between launch and the satellite being set healthy will be at a minimum,” said 2 Space Operations Squadron Flight Commander Capt. Collin Dart in a statement. The satellite was launched Nov. 5 from Cape Canaveral Air Force Station in Florida aboard a SpaceX Falcon 9 rocket. The addition of SV04 to the GPS constellation marks another step toward making M-Code — a more robust GPS signal for military use — available to the war fighter. M-Code provides a more accurate GPS signal with anti-jamming and anti-spoofing capabilities, making it harder for adversaries to block or degrade. Lockheed Martin is the primary contractor for the 10 GPS III satellites and the 22 GPS III Follow-On satellites in development. The Space Force granted GPS IIIF Milestone C in July, clearing the way for production to begin. “M-Code signals are more-secure, harder-to-jam and spoof, and are critical to helping our war fighters complete their missions, especially in contested environments,” Tonya Ladwig, Lockheed Martin's vice president for navigation systems, said in a statement. “GPS III is a war fighting system and we are proud to be helping bring this critical capability to the men and women protecting our nation.” “The highly encrypted M-Code to protect GPS signals from jamming and spoofing is currently enabled on 22 GPS satellites of various generations; 24 are needed to bring the M-Code to the next level of operational capability,” Dart said. “SV04 brings the constellation to 23 M-Code capable vehicles.” The 24th M-Code-enabled GPS satellite, which will be the fifth GPS III satellite, is currently ready for launch. However, the launch is not expected until July 2021 at the earliest. Upgrades to the GPS ground systems and distribution of M-Code-enabled receivers to the field are also needed to get the advanced signal into the hands of war fighters. In addition to moving the constellation closer to M-Code availability, the addition of another GPS satellite to the constellation will provide greater access to the improved L2C and L5 signals to civilian users. “For our billions of civil users, it brings the count up to 23 L2C spacecraft and 16 L5 spacecraft,” said Col. Ryan Colburn, director of the Space and Missile Systems Center Portfolio Architect office's Spectrum Warfare Division. “For professional users with existing dual-frequency operations, L2C enables faster signal acquisition, enhanced reliability, and greater operating range. L5 is broadcast in a radio band reserved exclusively for aviation safety services. It features higher power, greater bandwidth, and an advanced signal design.” And according to Lockheed Martin, the GPS III satellites also include the new L1C signal, which provides improved civilian user connectivity. https://www.c4isrnet.com/battlefield-tech/space/2020/12/03/fourth-gps-iii-satellite-receives-operational-acceptance-in-record-time/

Posted on February 9, 2021 by Richard R. Burgess, Senior Editor ARLINGTON, Va. — Boeing has begun work to return the Harpoon cruise missile to operational status in the U.S. Navy's submarine force after a more than 20-year absence. Boeing received an $10.9 million Naval Sea Systems Command contract late last month to refurbish 16 Harpoon missile capsules and four all-up rounds of encapsulated Block 1C Harpoon missiles for the Navy's submarines. Work is scheduled for completion by December 2022. The UGM-84A Harpoon Block 1C missiles will be integrated on the Navy's Los Angeles-class submarines. The UGM-84A is encapsulated to be fired from a torpedo tube and has a rocket booster to propel it above the surface of the water and into flight. “I am happy to report that we will have the first refurbished [Harpoon] missiles delivered to the fleet in [fiscal] ‘21,” said Rear Adm. Thomas Ishee, director of undersea warfare in the Office of the Chief of Naval Operations, speaking Nov. 7 at the Naval Submarine League's annual symposium in Arlington. In a demonstration in the 2018 Rim of the Pacific exercise, a Harpoon was fired from the Los Angeles-class attack submarine USS Olympia at a target ship, the first time one was fired from a U.S. Navy submarine since the UGM-84A Harpoons were withdrawn from the force in 1997. The UGM-84A is encapsulated to be fired from a torpedo tube and has a rocket booster to propel it above the surface of the water and into flight. “The Navy has a deep inventory of Harpoon Block IC missiles,” said Sally Seibert, director, Cruise Missile Systems at Boeing, in a statement. “These missiles can be refurbished and reintegrated into the fleet in a shorter timeframe, and at a fraction of the cost, compared to purchasing new missiles — and that is exactly what our team is doing.” The Harpoon cruise missile is a combat-proven, all-domain anti-ship missile used by the Navy and more than 30 international customers, a statement from Boeing said. “Evolving over the years to keep pace with emerging threats, the Harpoon Block II includes a GPS-aided guidance system that allows for autonomous, all-weather capability — and can execute both anti-ship and land-strike missions. The more advanced Harpoon Block II+ adds a data link that allows for in-flight targeting updates.” “The shelf life of the Harpoon missile allows us to maximize existing capability by bringing this weapon back to the submarine fleet,” Seibert said. “Customers who currently have Harpoon missiles in their inventory are prime candidates for refurbishments, or even upgrades, to add this extremely viable and cost-effective weapon to their arsenal.” Currently, more than 600 ships, 180 submarines, 12 different types of aircraft and several land-based launch vehicles across the world are integrated with Harpoon missiles, Boeing said. https://seapowermagazine.org/boeing-is-refurbishing-harpoon-missiles-for-u-s-navy-submarines/
