GNSS Heading for LEO Missions

TR-DI HDA - Dual Antenna Heading OEM GNSS

Expanded Support for LEO Missions - Now with GNSS Heading

Patented Spoofing & Jamming Protections Built-In

The TR-DI HDA delivers dual-antenna GNSS heading and precision navigation for high-dynamics LEO platforms, built for missions that demand reliable PNT in increasingly contested orbits.

Radiation-tolerant reception holds up through the orbital environment. JAVAD's patented anti-jamming and anti-spoofing technologies protect signal integrity against both intentional interference and adverse RF events. Onboard high-speed interfaces streamline IMU and sensor integration, giving mission designers a complete heading, navigation, and orientation stack in a single unit.

Manufactured in the USA and backed by support from the engineers who built it throughout the full mission lifecycle.

House appropriators advanced a spending bill Wednesday that keeps overall NASA funding flat for fiscal year 2027. The committee approved the commerce, justice and science spending bill on a 32-28 vote, sending it to the full House. The bill provides $24.438 billion for NASA, the same as the agency received in 2026 and rejecting a proposed 23% cut. The report accompanying the bill provided some additional details, such as calling for continued funding of several science missions slated for cancellation in the proposal. It also requires NASA to continue SLS and Orion until a commercial alternative that meets or exceeds their capabilities is proven. [SpaceNews]

NASA provided some more details Wednesday about plans for the next Artemis mission. The agency said that the Artemis 3 mission, scheduled for next year, will launch into low Earth orbit on an SLS without an upper stage. NASA will instead use an inert "spacer" with the same dimensions as the Interim Cryogenic Propulsion Stage (ICPS) flown on the first two SLS launches. That allows NASA to save the final ICPS for Artemis 4 in 2028, giving it more time to adapt the Centaur upper stage that will be used on later SLS missions. The Orion spacecraft will rendezvous with lunar lander prototypes from Blue Origin and SpaceX, although NASA is still working out details such as whether astronauts will enter those landers after docking. Artemis 3 will spend more time in space than Artemis 2, which spanned a little more than nine days. [SpaceNews]

Northrop Grumman is adapting technologies developed for the James Webb Space Telescope into a smaller navigation system for cislunar operations. Northrop said it developed a spacecraft navigation system called LR-450 that allows a vehicle to calculate its position, movement and orientation without relying on external signals such as GPS. The LR-450 system is based on technology it developed for JWST, which operates at the Earth-sun L2 Lagrange point. The system could also support applications intended to complement or back up traditional positioning, navigation and timing, or PNT, systems. [SpaceNews]

AST SpaceMobile may use United Launch Alliance's Vulcan rocket for some of its direct-to-device satellites. In an earnings call this week, company executives said that five of its BlueBird satellites could launch on a single Vulcan, compared to eight on New Glenn and three on Falcon 9. The company had not previously disclosed plans to use Vulcan, and declined during the call to confirm it has a contract, stating only that it has been "developing other heavy launch providers for some time." New Glenn has been grounded since a failed launch in April carrying a BlueBird satellite, but AST SpaceMobile said it expected the company to resume launches soon. Vulcan launches are also on hold because of a solid rocket booster anomaly in February. ULA said this week it has started stacking the Vulcan rocket for its next mission, carrying Amazon Leo satellites, while the investigation continues. [SpaceNews]

China's Zhuque-2 rocket returned to flight Wednesday night. The Zhuque-2E methane-liquid oxygen rocket, built by Landspace, lifted off at 11 p.m. Eastern from the Jiuquan Satellite Launch Center, placing a 2,800-kilogram test payload into polar orbit. It was the first launch of the Zhuque-2E since an August 2025 failure blamed on a voltage issue affecting the second stage, triggering a self-destruct. Landspace has incorporated improvements into the Zhuque-2E that allow it to place up to 4,000 kilograms into sun-synchronous orbit and 6,000 kilograms into low Earth orbit. [SpaceNews]

Weather caused a last-minute scrub of a Falcon 9 carrying a Dragon cargo spacecraft Wednesday. SpaceX called off the launch about half a minute before the scheduled 6:50 p.m. liftoff from Cape Canaveral, Florida, citing violations of weather constraints. The launch of the CRS-34 cargo mission to the International Space Station is now scheduled for 6:05 p.m. Eastern Friday. [NASA]

OHB is partnering with Dassault Aviation on a spaceplane. The companies announced this week that OHB will provide a service module for Dassault's VORTEX spaceplane. Dassault announced last year it was developing a subscale prototype, VORTEX-D, with some funding from the French military. Dassault and OHB said the VORTEX-S would follow that prototype and is intended to provide cargo transportation to the International Space Station or future commercial space stations as part of an ESA program.

A Canadian private astronaut is funding the creation of a space institute. Concordia University in Montreal announced that Mark Pathy is donating 15 million Canadian dollars for the Mark Pathy Space Institute at the university. The institute will support research and student training in space engineering. Pathy flew to the ISS in 2022 on Axiom Space'x Ax-1 mission. [Concordia Univ.]
