Loitering munitions or kamikaze drones are effective weapons that cause high risk if they get into the wrong hands.



The invasion of Ukraine is typical Russian military action. Long-range cruise missiles are used against civilian and military targets. The thing in the use of the cruise missiles is that the Glonass/GPS systems are effective only if the location of the target is well-known. And another thing is that the system should know all the time if the target is moving. In the western military. 

The problem with the Russian missiles is this: are they accurate enough to make pinpoint accurate attacks? So are they shot at civilian targets on purpose? And how well do their systems stand against high-power ECM (Electronic Counter Measure) jamming? 

The attacks are followed by high-flying recon planes or satellites. The problem is that if the target is moving. The missile should know that thing or it misses the hit. New missiles are so-called kamikaze drones. They are cruising above the battlefield. The official name of those systems is loitering drones. They can use against things like cruise missile batteries. 

Those drones are like Aquila target/recon drones that are equipped with anti-tank or some other type of warhead. The Aquila was the system of the 70s. And there are more advanced systems that are replacing it. But basically, they are all similar systems. 

Those kamikaze drones are transmitting data to the command center. And when the target is visible the controller will give an order to dive against that target which can be a ship or main battle tank. They are normal recon drones that are equipped with a warhead. 

The difference between a kamikaze drone and a cruise missile is minimal. The famous "Tomahawk" cruise missile is the only BQM-119 drone that is equipped with a conventional or nuclear warhead. But "kamikaze drones" can patrol above operational areas and transmit data and then make the attack against the target. 

The kamikaze drones that are using radio control are vulnerable to jamming. The EMP strikes can also drop those things. When we are talking about pinpoint accuracy there are two or three types of internal navigation systems. The GPS is needed to locate the beginning point of the flight of the missile. Then the inertial navigation will take the missile to a certain point of the flight route. 

The other way is to use TERCOM (Terrair contour matching)-system. The TERCOM means, that the system uses a series of images that are stored in the memory of the computers to fly to the target. In that system, satellite or high-flying recon plane will make the 3D topography map by using radar or lidar. And then the missile will use that data to find the route to its target. 

And finally, the image recognition system or ATR (Automatic Target Recognition) will select the target by using scene-matching technology. That system has the image of the target stored in its memory. And when the image that the camera transmits matches with the image that the missile will aim to target.

The little bit more about Amelia Earhart


Amelia Earhart
(Picture 1)


Kimmo Huosionmaa

There have been big headlines of the case of Amelia Earhart in today's news. It's very sure, that if this woman known as Amelia Earhart survived the crash landing, would she send the emergency calls, but the question is, why those emergency signals were not taken seriously? If civilians heard those signals, what this woman send from the lone island, why they didn't contact the authorities or went there to look, what was the trouble? And if those messages would report to authorities, why they would not go to check, what was going on? The radio tracking equipment could locate the place, where emergency calls came, and then there would send an airplane or a ship. But why those emergency signals caused the reactions with anybody?


Those emergency calls would give by frequency, what is reserved only for emergency calls. And there would be more than one transmitter in the plane. The experienced pilot or any other adventurist ever left their life in the hands of a single device. So if the crew of the airplane wanted to give emergency signal they must only push the button and automatic transmission begins. The radios had the accumulator- or battery backup, and that's why that equipment ever left the person in trouble, even if they were in the adventure flight.


If there were sent only one transmission, that might be missed by one operator. But if those calls were given simultaneous, that would be no miss. Of course, those pilots knew about international emergency call signal, and the bigger ships were also heard that. If the emergency signals were heard, every ship in that area had to turn to that transmitter. Experienced radio-operator sends one message, waits for a reply and if there would be no reaction, that person would try again in a couple of minutes. And of course, Earhart had own secret code if Noonan were drunk or violent. Noonan is the very unusual name, and if this man made some mistakes, would those stories came to knowledge.  He was in service of Pan Am before this flight and the question is why this man retired? Was there something, what he wanted to hide?

Was it flying in drunk, or was he do something else in his flight career, and that is the reason. why Pan Am kicked this man away, even if this man made flight routes in Pacific ocean.  Some persons think that maybe this person was fly guns to IRA or cocaine from South America in the service of Mafia or even took part of shooting innocent people from airplanes in Africa or Brasilia, and that might be the reason to kick this man off the Pan Am. Or maybe this man was homosexual, and that was red clothes to Pan Am directors. There are many stories about this tragedy, and maybe they are only legends. And there are many false claims about this kind of cases. But why Noonan retired from his job and wanted to establish the new pilot school in Florida, might have some connections to the case of Earhart.


Many of those photographs that are taken from those persons together are like situation pictures. Not portraying pictures, and in some of those pictures that are taken with sponsors and other men, Noonan seems to act like some kind of "boss". And he seems very serious person. He seems like bothering about publicity and Earhart was actually seemed like more relaxing. In some photographs Noonan  had suit on, and he seems like to act something else than pilot.

There are many theories what happened on that plane. Sometimes I have faced theories, that those pilots committed suicide. In this theory both of them had cancer, and they knew that they would die, and decided to make the suicide for avoiding pains, what that sickness causes. Another version of this theory was, that the family of Amelia Earhart wanted to transform this magnificent woman more common.


And there were called the doctor's psychiatrical institute to make their delusion true. In this theory is the aspect that Earhart was rebellious like many other fascinated persons are, and then somebody of her family was called the psychiatrist to help them. And this was meant the end of this magnificent woman, who decided to make suicide. Those places had the bad reputation in that time, and maybe this could explain this sad accident. But we cannot say anything before the wreck of the airplane would be found.
