Jamming the GPS is not as easy as people think.





Russians are told that they can jam the GPS. The war in Ukraine has shown that jamming the GPS is not as easy as people think. The communication between GPS and satellite happens with multi-channel radios. So the system uses multiple frequencies at the same time. 

That's why jamming the GPS is more difficult than people expect. The data security of those systems is very important. And maybe NATO uses different GPS in exercise than in real situations. That makes jamming of those systems extremely difficult. 

When people are looking at the Russian sea-launch missiles they are not very accurate. There is the possibility that small drones or special warfare teams are taking the radar transponders to targets. That thing makes targets seem brighter on the radar of the missile. And people expected Russians have those transponders. That thing can give the radar-homing missile higher accuracy. But Russians seem to have not those transponders. 

The problem with HiMARS and other precision-guided weapons is that if Russians get one of them. They can find out those frequencies. Another thing is that Ukraine will not maybe need anything more than 20-50 HiMARS launchers. People always asked, why Ukraine would not get let's say about 300 HiMARS? Have you ever known about the apportioning of firepower? 

That means the firepower would be limited to the necessary level. The GPS tells the precise point of the HiMARS to the deliverer of the system. But there is always the possibility that some Ukrainian criminals try to sell those weapons to Russians. Those weapons cannot use against Ukrainians or NATO. But they can give information about what the Russians need to break the GPS. 

The answer is there is always the possibility. Those Russians capture those systems. Another fact about the HiMARS is that weapon manufacturers are making more of them if there is a need for those systems. When we are talking about the HiMARS and other types of weapons we must realize that the U.S stockpile of those systems is not public information. 

And there is always the possibility that some Wikipedia data about those systems is wrong. Another thing is that the only allowed sources for comments on the war are public data. Uncovering classified information can cause big problems for national security. So Wikipedia and some FAS.Org type pages are allowed sources. The classified and top secret files are not public sources. They are not also allowed to use in commentations. The links below this text are going to news that is in Finnish.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
