India has achieved a major milestone in aviation by successfully demonstrating a precision landing of a passenger aircraft using its indigenous GAGAN satellite-based navigation system. Developed by ISRO and the Airports Authority of India, GAGAN enhances GPS accuracy and could improve flight safety, reduce infrastructure costs, and enable more precise landings at airports across the country. Could satellite-based navigation systems like GAGAN become the future of aviation and reduce the need for traditional landing systems? #ISRO #GPS #navic #indigo #navigation #navigationsystem

Introducing Raptor—a first-of-its-kind software suite that unlocks next-gen GPS resilience for autonomous drone systems. Now, when GPS goes blind, your mission doesn’t have to. These software products use a drone’s native camera and Maxar’s unique global 3D data to deliver a breakthrough terrain-based positioning system. Drones can navigate with extreme precision and extract accurate ground coordinates in the absence of GPS. Take a closer look: #autonomy #drones #GPS #UAV #UAS

🇮🇷 Iran’s “low-cost” cruise missile navigation is smart layering They combine 3 layers: -Cheap commercial GPS for basic positioning -Inertial navigation to keep flying without signals -Terrain matching to correct errors using preloaded maps and ground scans The key is terrain matching, where the missile compares the ground below with stored elevation maps and continuously corrects its path in real time, even if GPS is jammed. Nothing revolutionary. This tech exists for decades. What matters is the approach: cheap components, open data, and multiple backups working together. End result: not perfect, but reliable enough to hit targets without needing a military satellite network. Source: loadedlore YT

Unlike the West, Russia has always had a long-term Black Sea strategy. Based on aggression, piracy, and attacks on freedom of navigation. Together, we must put the bully in its place. So that freedom of navigation and international law are protected in the Black Sea and beyond.

🚨🇺🇸 SPACEX LAUNCHES GPS III-7: NEXT-GEN SATELLITE BOOSTS DEFENSE AND CIVILIAN NAVIGATION SpaceX launched GPS III-7, the latest next-generation satellite that will revolutionize navigation for both military and civilian users: "Today's mission is also Falcon 9's 7th launch of a GPS satellite, helping provide everyday navigation on your phone and in your car in addition to enabling autonomous vehicles, disaster response organizations, banking transactions, advanced defense capabilities, and more. GPS-III is the next generation of satellites required to maintain the GPS constellation's resiliency and improve services to meet user demand." The Falcon 9 booster completed its fourth flight, previously launching cargo to the ISS, a classified mission, and Starlink satellites. SpaceX's reusability continues to drive down launch costs for critical national security missions. This marks SpaceX's second accelerated mission for Space Force, proving private innovation can deliver defense capabilities faster and cheaper than traditional contractors. Every smartphone, bank transaction, and military operation depends on these satellites. Source: SpaceX
