The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.
The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
Gee, thanks Tuck. Now not only does my brain hurt, but my hair hurts and my teeth itch. Many thanks for that heads up. Sorta like the guidance system on the old Terrier M and Posiden missles I used to work on for Sperry Gyroscope in NY!
I used to write software for Medicare, Medicaid and MediCal submissions for specialist Doctors. The shenanigans those guys used to try to pull would put an IRS auditor to shame.
However devious the Doctors were, the worst part was in trying to make a dead-logical reasoning device (computer) understand and follow rules written by an army of government busy-bees. Convincing a computer to follow self cancelling and contradictory rules was as interesting as a conversation concerning relative motion theory with the Red Queen.
To me that would explain why the Missle Guidance System is flawed. It's flawed because it chooses the wrong mathematical system to follow. It should work through Missle Radar Systems that every nation can develop for low costs. You track a missle either through Atmospheric Heat Anomalies through the satelite system (although from what I know, I can't remember there being a satelite that was designed or is being designed for Heat Anomalies through NA skies).
To me this is how the system works, or should work. There is a missle somewhere, that just got launched. First thing you have to do is use targetting systems that can locate this missle, may it be through advanced radar detection systems or as mentioned Heat Anomaly systems (none existent yet>?), once you find there is a missle, you have to make pin point trigonometry and "ping" the target through the radar systems to determine it's protected velocity/altitude/area of Min/Max impact zone. Once that is determined (5 seconds), then a Missle with a programmed hit zone is sent. What typically happens is that missle's pre-programmed flight was miscalculated due to a wind error function that was entered. This is how I do believe the system works.
It can also work through constant radar updates of where a Missle is going, you send in a squadron of missles to hit that missle through near light speed updates of the missles trajectory. But the problems here is there are frequent anomalies that occur through trajectories when dealing with missles, along with the missles that are trying to destroy the "boggy".
Now yes there are atmospheric graphings that occur quite frequently that are almost correct, provide a great wealth of information when dealing with missle strike zones. In which when you got the missle projected strike zone, you basically send a missle to a particular area of the sky to "intercept" that missle and hit it or not. You can great a great explosion to just destroy the missle. Although with scud's, even when you hit the missle, you wont destroy the warhead. So you have to have a big enough explosion in the sky to eliminate the warhead that is on a missle.
The Patriot and Arrow systems are a waste of money, because they are flawed through the math. They want to hit a target, but with a small explosives package that is inside the arrow/Patriot systems. You need to create a mini-nuke explosion in the sky to destroy the missle if your dealing with Scud's.
Although am interested in information that might prove me wrong
"It should work through Missle Radar Systems that every nation can develop for low costs. "
Not at low cost. Any low cost system could be easily confused by Electronic Countermeasures. Also, it takes a lot of long range radar (very expen$ive) to detect incoming missles in space from every possible angle around a nation's entire perimeter.
"You track a missle either through Atmospheric Heat Anomalies through the satelite system......"
Do you have any idea how many jet aircraft (heat anomalies), civil and military, are in the air, worldwide, at any given time?
And how about temperature inversion layers, rapidly changing cold or warm weather fronts, forest fires, volcanos, house fires, etc., etc., etc.
"Marge, I'm going out to burn the trash"......BLAM!
You can develop a system in where, it is centrally connected with all pre-known flight plan's, along with having identification hashing's on anything that can be classified as a heat anomaly. I'm certain if more studies went into heat anomalies, there could be a successfull system developed to be quite accurate into tracking Missles. I would expect this HE system to be also connected with Long Range radar systems.
When I said low cost radars, you have a large connection of low distance radars. Put the radar systems near the borders of nations, in allying nations, that can be involved in a mutual agreement to be involved in this global Low Radar system that is specifically designed for boggy's. A cost effective program for a global radar missle detection system would cost you in the range of $50 million for research and dual use capabilities. The rest you try to find which radar systems can be developed into your system, and also creating field tests to see if this is a system that can work.
I believe it can work with the proper foundations of discussion, being based on global monitoring of missle launch platforms, along with mobile launch platforms.
With certain missles you have certain guidelines. The US knows most if not all of the missles that are avalible and/or are being created. The range, max payload warhead amount, and service altitude of the missles. Knowing the capabilities of the missles can increase the success rate of a Satelite Heat Anomaly system, which works with other ground workstations, such as low radar distance systems.
Forgot to add that, how many civillian aircrafts fly at the edge of space? Exactly. The Mig-25 can do it, but otherwise then that you can create the heat Anomaly system.

Just so you are informed, and take it from me, as soon as Tuck gets here he will explain. You know nothing of what you just wrote on the two posts. the only radar system capable of tracking and diseminating "bad guy" targets is a phase array system. It is what we use today. I happen to know this as I worked on designing these systems. KTX a major contributor to these phase array systems is Ratheon in your neck of the woods MA. If you think a cheap tracking or heat signature radar is going to give you discernable targets, you are wrong!
After service to my country, 1967 to 1972 I was rehired into Sperry Gyroscope (they had to give me my old job back or equivelent) in Great Neck, NY where I sat at my old desk 24 hours after being honorably discharged from the Marine Corps at Quantico, VA.
I worked on Submarine radars and also SPG-34 phase arrary radars and also Terrier M tracking radars.
If I told you more, then I would have to make ammends to our government.
