Is your GPS equipment vulnerable to spoofing? The government wants to test it.
Nathan Strout
This summer, the Department of Homeland Security's Science and Technology Directorate is hosting an event where owners and operators of critical infrastructure, manufacturers of commercial GPS receivers, and civil industry stakeholders can see how their equipment holds up under a spoofing attack.
“Accurate and precise position, navigation, and timing (PNT) information is vital to the nation's critical infrastructure,” said Bill Bryan, the senior official performing the duties of the undersecretary for science and technology. “[The Science and Technology Directorate] established this program to assess GPS vulnerabilities, advance research and development, and to enhance outreach and engagement with industry. The objective is to improve the security and resiliency of critical infrastructure.”
Slated for this summer, the 2020 GPS Equipment Testing for Critical Infrastructure event will be the third of its type hosted by DHS that allows parties to test their equipment against GPS spoofing in unique live-sky environments. This event will focus mainly on fixed infrastructure applications, though there will be some support for testing ground-based mobile applications.
There are no registration fees for participants, and interested parties have until April 24 to sign up.
Though originally developed as a military tool, GPS technology has become a constant presence in civilian life over the decades, enabling agriculture, telecommunications, financial services, weather forecasting, the electrical grid and more. An RTI International report released last year estimated that a 30-day GPS outage could result in economic losses to the tune of $35-45 billion.
U.S. adversaries are well aware of the country's reliance on GPS, both in the civilian world and by the military, and they have developed tools to degrade, deny or spoof that signal.
In recent months, the U.S. government has raised concerns that relying solely on GPS for PNT data leaves the nation's critical infrastructure vulnerable to attack. To help address this, President Donald Trump signed an executive order Feb. 12 calling for the U.S. to develop alternative sources of PNT data that can supplement or replace the GPS signal, should it become unreliable.
Under that executive order, the White House's Office of Science and Technology Policy will be developing PNT services independent of GPS and other global navigation satellite systems, while at the same time working to increase the resiliency of critical infrastructure by having them incorporate multiple PNT sources.

Airbus explores A320neo military derivatives
Airbus has revealed that it is exploring the introduction of military derivatives of the A320neo family. Speaking at the Singapore air show, Fernando Alonso, head of military aircraft at Airbus Defence & Space, said that the new platform could undertake missions such as VIP transport, intelligence, surveillance and reconnaissance and maritime patrol. "We have the knowledge of converting the A330 into the A330 MRTT [multirole tanker transport], and have a more efficient process." Alonso says that the efficiency of new-generation engines will enable a more capable military derivative. Any future conversion will require between "six to eight months" to complete, he says. Airbus is in talks with a number of operators, including the armed forces of Asia-Pacific nations such as Indonesia, Malaysia, New Zealand, the Philippines, alongside European stalwarts France, Germany and the Netherlands. The airframer is also working to add new capabilities to its existing military platforms: the A400M, A330 MRTT and C295. It will allow A400M operators to drop up to 60 paratroopers from both sides of the aircraft simultaneously, while the A330 MRTT is expected to be ready to conduct automatic air-to-air refuelling "in less than three years". Airbus is also exploring the possibility of allowing the remodelled widebody to take on ISR missions. Airbus is still proceeding with an "armed version" of the C295 medium transport, with the derivative in the engineering, development and testing phase. Flight tests will begin in late 2018. "There are big opportunities for us in Asia-Pacific: big fleets are here, budgets are here. We are able to fulfill needs in a more agile way," says Alonso. https://www.flightglobal.com/news/articles/singapore-airbus-explores-a320neo-military-derivati-445670/

Army Halts Apache Helicopter Deliveries
For the second time in two years, the Army had to stop accepting Boeing's attack helicopter. The exact reason remains unknown. Marcus Weisgerber The U.S. Army has stopped accepting Apache helicopters from Boeing after the company found that an employee kept “improper” records concerning parts installed on the aircraft. It's the latest quality-control issue to bedevil America's largest planemaker, which is trying to shift its company's culture and repair its public image after two deadly airliner crashes and a production line that left tools and trash inside new tanker aircraft. “At this time the Army is still conducting a comprehensive review of a number of Boeing processes, production, and manufacturing plans for critical safety items applicable to all AH-64E aircraft production,” Lt. Col. Brandon Kelley, an Army spokesman, said in an emailed statement. When it learned of “improper record keeping” at its AH-64 Apache factor in Mesa, Arizona, Boeing “immediately notified the Army,” Steve Parker, vice president and general manager of Boeing Vertical Lift, said in a statement provided by a company spokesman. “Boeing and the government are jointly reviewing our Mesa quality management processes and procedures,” Parker said. “Flight operations and deliveries will resume when Boeing and the Army are satisfied this issue has been resolved and appropriate corrective action plans have been implemented.” Boeing no longer employs the worker who kept the improper records, according to a person with knowledge of the issue. Boeing's Mesa operation builds new Apaches and overhauls old ones with more modern equipment — a process known as remanufacturing. The company continues to build aircraft amid the delivery stoppage, an industry source said. “The Army will begin acceptance of aircraft once conditions have been satisfied to ensure production processes meet standards for safety and quality and the potential for future quality escapes has been fully mitigated,” Kelley said. “The Army will continue to work with Boeing in reviewing their quality processes and manufacturing of critical safety items and recommend changes as necessary to prevent future delivery of non-conforming product.” Kelley said that soldiers' lives were not put at risk by the issues. It's not the first time the Army has suspended Apache deliveries. From March to August 2018, the service halted acceptances after finding a flaw in a part that holds the helicopter's rotors to the aircraft. Boeing quality-control practices have been called into question by both the commercial industry and the military. The Federal Aviation Administration is investigating potential manufacturing issues on 787 Dreamliner aircraft. The U.S. Air Force had to halt deliveries of KC-46 tankers on numerous occasions after military inspectors found trash, parts, and tools left inside the aircraft. In March 2019, Will Roper, the head of Air Force acquisition, blamed the company's assembly line culture for the issues. The coronavirus pandemic has only made things worse for Boeing and its suppliers as air travel evaporates and airlines cancel plane orders. Earlier this year, executives said the company's $34 billion defense business would outperform its typically lucrative commercial business for the first time in more than a decade. Coronavirus-related factory shutdowns and production slowdowns started taking a toll on Boeing's defense business in the spring. Boeing delivered 54 fewer military aircraft and satellites so far this year when to the first three quarters of 2019, a 31 percent decline, according to company data. This year, Boeing has delivered 10 KC-46 tankers, less than half of the 21 delivered through the third quarter of 2019. https://www.defenseone.com/business/2020/10/army-halts-apache-deliveries-after-boeing-finds-improper-record-keeping-helicopter-factory/169332/
