Raytheon wins $234 million US Navy contract for 23 Joint Precision Approach and Landing Systems
PARIS, June 17, 2019 /PRNewswire/ -- Raytheon (NYSE: RTN) won a four-year $234 million initial low-rate production contract from the U.S. Navy to outfit all of its nuclear-powered aircraft carriers and amphibious assault ships with 23 Joint Precision Approach and Landing Systems. JPALS is a GPS-based precision landing system that guides aircraft to precision landings in all weather and surface conditions.
"The U.S. Navy understands how JPALS contributes to their mission success and safety of its people," said Matt Gilligan, vice president of Raytheon's Intelligence, Information and Services business. "Other military services could also benefit from the system's ability to safely land both fixed and rotary-wing aircraft in almost any low-visibility environment."
Since 2018, U.S. Marine Corps F-35B Lightning II fighter pilots have used JPALS to guide them onto the USS Wasp amphibious assault ship during deployed operations in what U.S. Navy Captain B. Joseph Hornbuckle III, program manager, Naval Air Traffic Management Systems Program Office called 'the most difficult conditions on Earth."
Earlier this year, F-35B pilots participated in two demonstrations of a new expeditionary version of the JPALS system that brings the same precision capability from sea to shore. The proof-of-concept events showed how the GPS-based system could be reconfigured into a mobile version to support landings in a traditional airport setting.
Expeditionary JPALS fits in five transit cases and could be repackaged for a variety of small transit vehicles transportable by C-130. Once on the ground, the system can be fully operational in under 90 minutes.

The Air Force will need terminals that work with more than GPS
By: Nathan Strout Congress wants the Air Force to develop a prototype receiver capable of using navigation signals provided by other countries, which could increase the resilience of the military's position, navigation and timing equipment. The primary source of the military's PNT data is the Global Positioning System, a satellite system operated by the Air Force. But with adversaries developing GPS jamming technology and anti-satellite weapons that could potentially knock out one or more of those satellites, Congress wants a receiver capable of utilizing other global navigation satellite systems. The annual defense policy bill, which was passed by both chambers of the legislature this week, calls on the Air Force to develop a prototype receiver capable of utilizing multiple global navigation satellite systems in addition to GPS, such as the European Union's Galileo and Japan's QZSS satellites. The belief is that if the GPS signal is degraded or denied, war fighters could switch to one of those other systems to get the PNT data they need. According to Brian Weeden, director of program planning at the Secure World Foundation, the provision represents an evolution from the Department of Defense's stance on foreign GNSS signals from 15 years ago. “When Galileo was first announced, there was a big debate within the Pentagon about whether to cooperate with the Europeans or try and kill it,” Weeden wrote to C4ISRNET in a Dec. 18 email. “The big driver there was that the Europeans were going to park their protected signal on top of M-code and then sell their service as being unjammable by the Americans (assuming that the US couldn't jam the protected Galileo signal without also interfering with M-Code).” Efforts to kill Galileo ultimately died, Weeden noted, although the EU did move their protected GNSS signal off of M-Code, a more secure military version of the GPS signal that is in development. That concession and the subsequent development of GPS jamming capabilities by Russia and China has changed the thinking on Galileo and other GNSS signals. “It seems the Pentagon has decided that leveraging Galileo will make their PNT capabilities more robust as Russia or China would need to jam both of the separate military signals,” said Weeden. “There's some engineering and technical wizardry still to be worked out to create a good multi-GNSS receiver but it's doable.” Congress wants the Air Force to report on the benefits and risks of each potential GNSS signal, and it fences 90 percent of the funding for the Military GPS User Equipment Program until lawmakers receive that report. https://www.c4isrnet.com/battlefield-tech/space/2019/12/19/the-air-force-will-need-terminals-that-work-with-more-than-gps
