The band may bring closer the possibility of the existence of an Israeli band flight in orbit around the earth and will enable the simultaneous operation of up to four satellites in space for photography and navigation purposes, with unprecedented qualities
The researchers of the Faculty of Aeronautics and Space Engineering established a unique laboratory of its kind in Israel, for the development of flights of satellite "bands" in space. The laboratory contains a facility designed and equipped with the aim of testing methods and equipment under conditions as close as possible to the actual operating conditions in space, including joint control, relative position control and angular position sensing. The advanced equipment in the laboratory includes a large air table, models of space vehicles and sensing means.
"At the beginning of the 21st century, space engineers face a new challenge - to develop and carry out small missions in space that will be exciting from a scientific point of view, fascinating from a public point of view, and practical from a financial point of view," says Dr. Pini Gurfil, head of the laboratory. "In order to face these challenges and promote Israel's scientific and technological goals in space, we established the laboratory."
In the laboratory, Technion researchers simulate the simultaneous flight of small satellites in space, which cooperate with each other and are also easy to replace in the event of a malfunction. The system is designed to replace large and cumbersome satellites operating today. The "satellites" built by Technion researchers move on the air table and the communication between them is based on ZigBee, which is a wireless broadband communication method for short ranges (up to tens of meters).
The Technion researchers believe that thanks to the innovative system, small satellites will in the future be able to take a simultaneous photograph of every point on the earth, which will significantly improve the quality of the photographs and allow realistic XNUMXD images to be obtained. Yes, giving will be possible Local satellite navigation services And you will be able to photograph star systems for the purposes of astronomy and space exploration.
The laboratory was designed in collaboration with engineers from the Asher Space Research Institute at the Technion and the Tsikel Engineering company, and was built with funding from the Technion, the European Space Agency as part of the "Galileo" project (the European satellite navigation system) and the Ministry of Science.

Then like in an array of telescopes. The satellites created an observation capacity greater than that of a single telescope.
without investing in one large satellite.
It would be possible to count the lice on Ahmadinejad's head from a height of 600 km."
To all the commenters who did not understand the Technion information
It goes without saying that the Technion graduates enjoy our pleas, and prefer not to explain and keep the knowledge in their small pockets, because my expectations from the Technion graduates (of which there are many among the science readers, and I know at least one) to receive an answer, aim for zero, I allow myself to share my scant knowledge with the thirsty science responders know.
Well, the idea of using a band of nano satellites is a very successful idea in all respects. You can always send one or two more satellites to replace the broken ones.
The idea in photography is that the distance between the nano-satellites, tens of meters, actually constitutes the new diameter of the lens so that the nano-photographs, if done in a coordinated manner, will be able to photograph items on the surface of the earth very sharply, and even... Tiny planets in distant solar systems!
This idea is a well-known idea that is carried out on the ground in radio telescope farms and also in conventional telescopes, for example the pair of KK telescopes in Hawaii.
So much for the meager explanations and the Technionists knew that Israel was not a widow, and there is a reward for their knowledge.

"Science and Nature"
That sounds like an interesting idea
In short, lots of arguments without any content.
Jewish nation…
Is this a type of autism?
Dear respondents 2,4, 5 and XNUMX,
Maybe I asked a stupid question,
This is certainly possible since I have no background in the field,
But nothing will happen if you explain to me why she is stupid,
And it will surely be better than childish and arrogant responses.
In short: there is no shame in saying "we don't know",
And it's even better to apply the proverb: "A caveat to wisdom - silence".
In a new test, the Technion found a new type of infantils that until now had not been discovered by science. Our reporter was told that the nickname given by the scientists to the new type is Enfantilo-Cinniman and it also includes just ignorant fools who think they know everything after a half-hour program on Channel 8.
Give me your email and I'll send you exactly their frequencies...
I just don't want anyone to intercept them, you know?
come on.
I don't understand why you have to be cynical?
The person asked a question, it's better not to respond if you don't have a smart answer.
It also sounds strange to me personally, why do you need several satellites at a distance of a few meters from each other? Why is this an advantage?
Why not spread them over a larger space?
Gedi, thank you. I did not think about it. Really, the range is too short and now I will have to change the whole plan, including the laboratory.
So let's see, we lost 25 million dollars in fraud, let's say another 25 for the laboratory, I get 50 million dollars here. oh ok Better early than late.
Thanks again Gadi, you how are you okay.
Are they supposed to communicate in ZigBee even while moving in space?
Isn't that too short a term?
Or are they planning a huge launch of hundreds of satellites?
