So we need to define some terminology.
GPS: Global Positioning System
INS: Inertial Navigation System
IMU: Inertial Measurement Unit
Gyroscope
Accelerometer
EGI: Enhanced GPS aided INS

So all navigation systems have at their core an IMU. The IMU is a six axis inertial measurement package 3 linear using accelerometers and 3 angular using gyroscopes. There are canned computational algorithms that take the IMU data and use it to determine how the host platform moves across the earth (or more generally thru space, even beyond the atmosphere ala moon shot) that system which takes that IMU inertial information and computes a navigation solution is called an INS. And until the advent of GPS that was it. We had inertial nav with the navigator taking a manual celestial fix to update the INS solution at various intervals. This provided corrections to the “free navigation” solution. Then along came GPS and those fixes now became automated along with how they corrected the errors in the INS measurement package, the IMU. This correction method uses a statistical state estimator that estimates the errors in the IMU and provides correction factors to the IMU and allows the INS to achieve a more accurate solution. So when you take an INS and combine it with a GPS receiver you get an EGI.

So the INS uses gyros for rotational measurements and accelerometers for linear measurements and creates a track history for the host platform carrying the INS. And the modern INS combines with a GPS receiver to create an automatic error correcting navigator which we refer to as the EGI. You can actually buy a text book in this day and age that illustrates the basic navigation equations in standardized form.

Did that answer it?

Edit: for completeness the INS uses 7 pieces of information not 6. The 7th is time. Very very very accurate time. The 6 axis IMU and time are combined by textbook equations to provide the navigation solution which answers the two basic questions. Where am I and when am I.

IN other words they can put one right thru your front door or in the bed of your truck while you are driving 60 miles an hour down the road. That is the math I understand:)

I agree...a paradigm shift where an infantryman can kill a tank as much a distance as the tank gun and actually more precise. You dont shoot tank rounds at "guys":
Carriers, all surface escorts and amphibians and all sorts of major assets are just waiting too be sunk in the next major war. With such lethality and precision, disbursement and stealth are key..in my novice opinion.

Much like cloud and blockchain has demonstrated the survivability and resilience of distributed systems, the next wave of war is likely to be the remotely (and auto) piloted swarm. The killer crock is giving way to the piranha.

Imagine a swarm of 100 cheap disposable drones with a range of 100 miles and 3 hour fly time and 1 kg payload, guided by a grid of high flight rotating observational drones and supported by 2 reaper drones for hardened targets. The swarm flies low to ground, cant be detected by most radar and is perfectly synced to the rest of the swarm. Once at their target, they explode in unison - followed by ordinance from Reapers for any surviving targets. OR the swarm can disperse in groups of 2 or 10 to follow after any moving or heat signature, though doorways and buildings. Artificial Intelligence paired a with human control team that could be 1000 miles away as long as there is a local launch team. Essentially, a flying smart cluster bomb.

Nothing will survive this robotic swarm, neither armor nor infantry. It is almost impossible to target any single device and each can be replaced with ease. That is the future - and it is very VERY close.

The longer China waits and works the buying of politicians the better off they are. However contrary to the Russian clown show military, China is a real force and would indeed over take Taiwan in a week or so if we didn’t intercede. And do so without massive collateral damage. And if we’ve shown no intestinal fortitude to impede that campaign then there is no reason for them to wait. Thus why shutting down Putin in Ukraine now is so important and forcing China to continue the long play soft invasion tactic.

Maybe, but the Chinese military may not be the force you think - or even better than the Russian military. The thing about China is that there are a lot of them - hordes; and the developed countries are funding their military and allowing China to steal technology. An invasion without destroying Taiwan would be interesting. There's a big difference in driving an 8 mile long convoy overland vs landing on beaches. The smart move would be the formation of an Asian organization similar to NATO so there is no question about Taiwan's independence and defense.

Most people, despite what they may now say, expected Russia to roll through Ukraine without much trouble. I don't think an amphibious invasion of Taiwan would particularly easy for China if they chose to go for it.

Well, It's out of my hands how he goes, but go he will, he has gone too far. I find it fascinating that he disappeared again. He has to be moving from safe house to safe "bunker" right?

There is a rumor out there from the Ukrainian side that is not hard to find. It says that Putin travels with a half dozen doctor "specialists", and may be gravely ill.

Food testers. Putin likes ricin rice in his soup. He needs to make sure nobody confuses the order.

You, know it is hard to imagine what tomorrows modern day battlefield will look like. I have often said that I hate the remote drone thing. IT seems too much like a video game. Experiencing the horrors of war is sometimes the only thing keeping the leadership sane. Russia has learned that Tanks are going the way of the buggy whip. I think it will become a battle of electronics between the major powers and small brush fire wars in the proxy wars, I am not sure the modern day battlefield is surviveable between two modern armies. I am talking minus the nukes.

Best just not to go there. Respect other people's borders, and everybody stays reasonably safe. There is a role for large nations and alliances in protecting others from invasion; if we forget that, we are no better than the bullies.

If we miss by 25M today with an “precision” weapon we are off by a time zone.

Depends what kind of weapon it is. Some can be off by 25 meters, yet still vaporize everything within 150 meters. On an AC-130 their old (not sure if its newer now) laster target designator (LTR) could f#ck you up on its on by it painting you on the ground from the sky. Then of course there was the inevitable explosive 105 shell landing within 10 meters of you which would finish the job.

You don’t think NATO has any blame in this??

What country did NATO invade? How many Russian/Communist soldiers did NATO kill during their invasion?


This is an old fashioned land grab. Putin is old and suffering from "nostalgia" about the good old soviet days, which were terrible unless you were in power.

I dont even have a word to accurately convey how staggering these losses are. 7 ships and they aren't even fighting a navy. Almost 30% of their entire inventory of tanks. The helicopters and aircraft..the financial hit is almost unfathomable. Then of course the human cost.

I wonder if Russians will ever find out about this? I'm sure Putin will spin all of the losses as part of their space initiative to rid Nazi's from the moon after he saw a documentary about Hitler living there and the great Western Satan NATO refused to supply the re-entry vehicles and fuel so now everything is on the surface of the moon that you can't ever see with a telescope from Russia no matter how hard you look.

Yeah, they said the same type of bs when Trump was in office.

Which raises a sincere question. Are you so gung ho pro Vlad because that's being loyal to Trump, or what? Everything you post is pro Russian, everything. There's no objectivity at all, just a stream of apologetics and propoganda. I mean a lot are pro-Ukraine but know that they've got their own serious flaws.

"Over the weekend, U.S. intelligence analysts warned that Russia was massing forces for a large offensive out of now-captured Izyum all the way to Dnipro, a distance of over 200 kilometers. U.S. intelligence has been on point throughout the war, but to outside observers the move seems utterly implausible. It would be an operation equal in scope to the Russian attack on (and retreat from) Kyiv, but facing even longer supply lines, routed through even less defensible territory, in the face of stiffer potential Ukrainian resistance and utilizing battalions that have suffered heavy losses since the first days of the war. There's no part of that calculation that works out well for Russia, even taking Ukraine's own heavy casualties into account.

That doesn't mean Russia won't try, and what we've seen from U.S. intelligence so far seems to hint that they have a much easier window into what Russian leader Vladimir Putin's inner circle believes than what Russian military realities actually are. It's very possible that Russia will attempt the unfathomably risky move because Putin and whatever generals still have Putin's favor are demanding that their underlings do it. And it's very possible that it could end in a shredding of those Russian forces that makes the Russian losses elsewhere pedestrian in comparison. The latter possibility is even more likely as NATO countries abandon their previous reticence at providing so-called "offensive" weaponry to Ukraine and are now opening the equipment floodgates."

Ukrainians being forced to fight by their corrupt regime.

NATO/US thought this was a fight they wanted...now, I dont know. At this point Russia seems to have the upper hand and the US/NATO seems to be having a hard time not only finding friends but even keeping those in their alliance true.

This seems to have been a terrible miscalculation for Europe and to a lesser degree, the US.

Lol. Such a twisted string of thoughts. Link to Ulraine forcing people to fight? As far as I have seen they havent closed their non Russian borders. The government provided guns so they COULD fight, not had to. There has not been an Order 227 of No Step Back enforced by a Commisar.

They only ones forcing people to fight in Ukraine is Russia. They are the invaders, occupiers, and foreigners. Russias direct actions lead to this conflict, no two ways about it.

He believes it therefore it is true. He is applying the George Costanza philosophy on lies.
