  Fourth GPS III satellite receives operational acceptance in record time

  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/

  US Air Force wants help seeing moving targets in its sensor data

  Nathan Strout WASHINGTON — The U.S. Air Force Research Laboratory has awarded Descartes Labs a $2.2 million contract to generate real-time analytics with a focus on developing moving target indication data, the company announced Oct. 27. Under this new contract, AFRL will gain access to the company's geospatial analytics platform, which uses artificial intelligence and computer vision to process and fuse sensor data, such as satellite imagery, for tactical use. Descartes Labs claims the focus of this contract will involve using its platform to help the Air Force solve the challenge of generating moving target indication data for ground and airborne targets. The New Mexico-based company was recently awarded a contract from AFRL and AFWERX — an Air Force effort to spark innovation through nontraditional vendors — that gave the service access to Descartes Labs' geospatial analytics platform for multi-sensor data fusion and situational awareness. The company has also worked with the Defense Advanced Research Projects Agency and the National Geospatial-Intelligence Agency, helping the firm further refine its approach. “Through the implementation of multi-sensor analytics, the Air Force is creating a forward-thinking state-of-the-art national security system,” Mike Warren, Descartes Labs co-founder and chief technology officer, said in a statement. “Through increasing use of diverse types of data, the Air Force is laying the groundwork to solve tactical intelligence, surveillance and reconnaissance problems now and in the future.” This latest contract was issued through AFRL's Space Technology Advanced Research program, which was launched in summer 2019 to develop enabling technologies for space-based capabilities, including on-orbit servicing, debris management, ground systems and more. http://9. https://www.c4isrnet.com/intel-geoint/2020/10/28/the-air-force-wants-help-seeing-moving-targets-in-its-sensor-data/

  Australia plans US$190 billion defence boost over decade

  Rod McGuirk The Associated PressStaff CANBERRA, AUSTRALIA -- Australia's prime minister on Wednesday announced 270 billion Australian dollars (US$190 billion) in additional defence spending over the next decade, which will include long-range missiles and other capabilities to hold enemies further from its shores. Prime Minister Scott Morrison warned that the post-pandemic world will become more dangerous and announced a renewed focus on Australia's immediate region, although its military would be open to joining U.S.-led coalitions as it did in Afghanistan and Iraq in campaigns that were in the Australian national interest. Australia had not seen such economic and strategic uncertainty in the region since the Second World War for reasons including tensions between the United States and China, he said. "This simple truth is this: Even as we stare down the COVID pandemic at home, we need to also prepare for a post-COVID world that is poorer, that is more dangerous and that is more disorderly," Morrison said. Tensions over territorial claims were rising between India and China and in the South China Sea, Morrison said. "The risk of miscalculation and even conflict is heightened," Morrison said. "Regional military modernization is at an unprecedented rate." "Relations between China and the United States are fractious at best as they compete for political, economic and technological supremacy," he added. Rory Medcalf, head of the Australian National University's National Security College, said the announcement showed Australia was "getting serious about deterrence and the prospect of armed conflict in the Indo-Pacific region." "It was only a matter of time before the Australian government made a choice about the kind of defence force that we're going to have in the 21st century with the rapid deterioration in the strategic environment in recent years," Medcalf said. "The government has accepted that the Australian military needs to be able to attempt to deter armed conflict through its capabilities and to be able to fight in our region if we have to," he added. Australia will invest in more lethal and long-range capabilities that will hold enemies further from its shores, including longer-range strike weapons and offensive cyber capabilities. To increase maritime strike capability, Australia will buy the AGM-158C anti-ship missile from the U.S. Navy at an estimated cost of AU$800 million, the government said. The new missile is a significant upgrade from Australia's current AGM-84 air-launched Harpoon anti-ship missile, which was introduced in the early 1980s. It has a range of 124 kilometres (77 miles), while the missile being purchased can exceed 370 kilometres (230 miles). The new missile will initially be used on the F/A-18F Super Hornet jet fighters but can be used by other defence aircraft. Training on the weapon system would begin next year, the government said. Australia will also invest in advanced naval strike capabilities, including long-range anti-ship and land strike weapons, and will buy long-range rocket artillery and missile systems to give the army an operational strike capability. It also plans to develop and test high-speed, long-range strike weapons, including hypersonic weapons. The announcement comes as Australia's relationship with China, its most important trading partner, is under extraordinary strain over Australian calls for an independent investigation of the pandemic. The United States, Australia's most important security partner since the Second World War, remains "the foundation of our defence policy," Morrison said. "Of course we can't match all the capabilities in our region," Morrison said. "That is why we need to ensure that our deterrence capabilities play to our strengths." https://www.ctvnews.ca/world/australia-plans-us-190-billion-defence-boost-over-decade-1.5006902
