Iceye and StarLink are the next-generation systems that can use for civil and military purposes.

Iceye is a Finnish startup company that creates miniature radar satellites. Those satellites can observe floods, cities, and many other targets. But those satellites can also give information about the movements of the enemy. Those miniature satellites are delivering target data from Russian troops and then send that data through the satellite communication systems to defenders. 

The radar satellite can make a 3D map image from the ground below it. And then computers can position that image on the radar map that covers the entire earth. The system compiles the form of the ground below the satellite and radar images that are in its memory. Then the system positions the image to the right point. 

The miniature radar satellites show their ability to search targets and send data to the customer in real-time. The miniature satellites are tools that can interconnect to one swarm. And that thing makes them very useful tools. The operators can make clouds around the Earth by using miniature satellites. 

And those systems can deliver information from any point on earth in seconds if those satellites are covering the entire planet. Radar transponders are tools that are giving more accuracy to those satellites. The radar transponder can be a miniature quadcopter that lands on the target. That transponder can also turn communication satellites into locating systems.

Another system like StarLink can offer communication tools. But the StarLink-type systems are also multi-use tools. They can also locate targets. 

The idea of that system is to use transmitters. And then three or four Starlink satellites use the triangular measurement for locating that pointer. The fact is that these kinds of systems are very useful tools for giving real-time position data to customers.  

But when we think about communication and radar satellites those satellites can also operate against things like drone swarms. The high-power radio bursts can lock the communication systems that are connecting drones to one entirety. 

If those radar or communication satellites are creating electric arcs to air that kind of system can also destroy at least high-flying aircraft. Maybe that kind of system cannot focus those cutting radiowaves on missiles. Can those systems destroy ground targets depending on their transmitting power? And the ability to locate their targets. But they can harm other satellites and slow high-flying aircraft.

How do quantum computers find and correct their errors?

   

 How do quantum computers find and correct their errors? 

Quantum computers are powerful tools. And even their researchers don't know the entire power of that system. But without an error-handling protocol, those systems are useless. The thing that the system is powerful doesn't mean that the system is trusted. 

The error handling process must be done before the quantum computers are turning trusted systems. That is delivering confirmed data. The error-location and error-correcting protocols are necessary for making full-function quantum computers. 

How do quantum computers locate and correct errors? Without that ability, the quantum system is useless. In normal or binary computers other computers will check the data. But the problem with a quantum computer is that the system would handle more complicated algorithms than binary computers. 

And the quantum computers might complete the calculation in minutes that takes the binary computers even thousands of years. So the binary computers are useless in this process. 

There is one thing that people must remember when they are talking about quantum computers. Quantum computers are more sensitive than binary computers. 

Things like gravitational waves and fast electromagnetic bursts like GRB:s (Gamma-Ray Bursts) and FRB (Fast Radio Bursts) can affect quantum computers. So that thing means that the error-handling capacity in the cases of quantum computers is in the key role for using them in trusted and confirmed operations. 

One version is to use two or more quantum computers for making the calculations. And if there are errors that would send the solution for the rethinking process. That kind of thing is one of the versions of the problem called error handling. 

Many things can make to ensure the results that quantum computers can get. One of them is to use control calculations. 

The well-known algorithms are giving confirmed results. And they can use for finding errors in quantum computers. 

And if there is a difference between the confirmed result and the result that is forming in quantum computers control drive. The quantum computer and its operator get information that there is an error in the system. Another way to ensure the calculation is to make the process multiple times. And if there are differences between results- There is some kind of mistake.

But before the quantum computer can benefit in full-scale operations. The error probability of that system. Must be determined. That thing can make by sending some simple calculations through the system billions of times. And the difference between answers is telling that there is some kind of error. In history, there is an example of a simple error in the function of the microchip. 

And that thing is called the "1+1 problem". When the microprocessor is handling data. By using extremely high speed. There is the possibility that some of its gates or switches are stuck. That thing causes that the computer will calculate the result of 1+1 being something else than 2. That thing causes problems with data handling capacity. The thing is that quantum computers are extremely powerful tools. 

But there is the possibility that some outcoming effect like GRB (Gamma Ray Burst) or gravitational waves can affect the energy level of the qubit. That thing means that the data is lost or it would release to the wrong states. So in the future. There is the possibility that in space will be satellites that are sending warning about incoming gravitational waves or GRB:s.
