Alright lets get started with NaviC then.
You are by now already aware on how basic ranging works and position is solved for from a GNSS constellation. We will look at a basic structure of the constellation, how the signal is generated, rcv'd and solved for.
THE STRANGE, IRONIC JOURNEY OF IRAN’S SHAHED DRONE 🚨
1970–1976
Iran under the Shah is a close US ally. Washington sells Tehran some of its most advanced military technology, including F-14 Tomcat jets and Phoenix missiles. Iran fields one of the most sophisticated air forces outside NATO.
1979
The Islamic Revolution ends the US partnership overnight. Arms supplies and spare parts stop. Iran’s Western-equipped military is suddenly orphaned.
1980–1988
During the Iran–Iraq war, Iran struggles to maintain its Western aircraft. Engineers begin improvising and experimenting with unmanned aircraft. Sanctions push Iran toward unconventional solutions.
1990s
Iran begins developing UAVs like Ababil and Mohajer. Iran’s core drone doctrine begins: cheap, expendable systems that can be built 100% domestically.
2000–2010
Iran quietly expands its drone ecosystem, reverse-engineering engines and electronics. Drones become a workaround for Iran’s inability to have a modern air force.
2011–2018
Iranian drones begin appearing across West Asia through allied militias, becoming a key tool of asymmetric warfare.
2019
A drone strike on Saudi Arabia’s Abqaiq facility temporarily knocks out about 5 percent of global oil supply. Cheap drones prove they can create strategic economic shock.
2020
Iran unveils the Shahed-136 loitering munition (the one you’re seeing now). A simple piston-engine drone designed for long-range optionally mass attacks.
2022
Russia begins using Shahed-136 drones in Ukraine, renaming them Geran-2. Swarms target cities and energy infrastructure.
2022–2023
The economics of an expensive war shift. A Shahed costs >$30k a piece. Missiles used to shoot them down can cost hundreds of thousands or even millions.
2023
Russia begins producing Shahed-type drones domestically, scaling up swarm attacks on Ukraine.
2023–2024
Ukraine adapts rapidly, developing counter-drone tactics, interceptors and jamming warfare. The country becomes the world’s drone warfare laboratory.
2024
World militaries begin studying Ukraine’s battlefield lessons on drone warfare and air defence economics.
2025
The US unveils LUCAS, a low-cost attack drone concept inspired by captured Shahed drones studied in Ukraine.
2025
India tests its first Shahed-inspired long range swarming drone Sheshnaag. Secret sauce: swarming code & autonomous attack modes.
2025
Pakistan employs cheap swarm drone tactics during Op Sindoor, supplied and tutored by Turkey & China to saturate Indian air defences. India’s counter-drone systems get their first major trial.
2026
In the current Iran war, Shahed drones hit ports, oil facilities, bases and cities across the Gulf, forcing Saudi and allied air defences to burn through expensive interceptors.
2026
The US and Gulf states turn to Ukraine for advice and technology. The country that defended itself against Shaheds is now helping others counter them.
2026
Two weeks into the war, Shahed drones are still hitting targets hundreds of kilometres away. The uncomfortable truth: the most advanced militaries on earth still lack a reliable antidote to mass-produced garage-style drones.
The Shahed arc is complete.
A country that once flew America’s most advanced fighter jets ended up building cheap drones out of necessity. Those drones go on to rewrite the economics of modern war.
Today was supposed to be a day of celebration for Bangalore. I can’t recall the last time the city was, collectively, so happy. It was incredible. But after the events that transpired today, I’m heartbroken. Sport is meant to heal and unite, not this. Authorities, this is on you.

IMO, Indigo crew did the right thing. Had Air India aborted takeoff, they could have safely performed a go-around. Air India was past V1 by the time Indigo was committed.
Had Indigo rejected the landing, there would have been two aircraft airborne, and in close proximity.
@volklub Have you faced any issues after replacing the battery, I too plan on doing this but have not received any inputs on what the performance is like after the battery upgrade
@TRE_320 1. A\THR call-out. Didn’t say “A\THR Blue”
2. SID on EFB.
3. Can’t see too clearly, but it doesn’t look like hand was removed from Thrust Levers after V1.
@TheBanat I don’t understand how an offside can be subjective! It’s either offside or not. Honestly what’s going on with these VAR decisions against United.
