A new nanosatellite built by researchers at Tel Aviv University (Israel) was put into orbit by a SpaceX Falcon 9 rocket from a launch site in California (USA), Tuesday January 10, 2023.
According to the researchers, Extremely small size nano satellite – only 20 cmappointed YEAR-SAT3is the first Israeli satellite built to advance research into optical and quantum communications technologies from space and is ““an important step toward demonstrating that quantum communication is truly reliable.”
Quantum communication is a method of information transmission that applies quantum technology, allowing data to be transmitted quickly and securely. The advantage of quantum communication lies in its extremely high security, which prevents illegal access to information and data. Quantum communication is also almost “immune” to hacker threats.

According to Professor Yaron Oz, director of the Center for Quantum Science and Technology at Tel Aviv University, the emergence of quantum computers is expected. “cracking today’s encryption algorithms”.
As a result, data such as personal medical and financial records, emails and WhatsApp messages will be leaked and stolen. Currently, the world is investing millions of dollars in research projects “anti-eavesdropping quantum communication”.
Quantum computing Harness quantum mechanics technology to quickly solve problems too complex for classical computers by processing massive amounts of data.
“The principles of quantum mechanics enable a secure encryption method that is considered impenetrable.”
“Whenever a malicious actor attempts to prevent a message from being transmitted, the message is immediately lost.”
The satellite, called TAU-SAT3, was launched on January 3 from the Cape Canaveral station in Florida.

At an altitude of 550 km (342 miles), the TAU-SAT3 satellite will orbit the Earth for approximately 5 years to carry out a number of scientific missions, while also returning optical and radio communications signals to the receiving station . on the roof of a building on the Tel Aviv University campus.
“This is the first transceiver station in Israel and one of the few in the world that can locate, track and collect data from a nanosatellite, which is only the size of a pixel ( approximately the size of a pixel equivalent to 0.26 mm) as seen from Earth, ” said Professor Noam Eliaz, Dean of the Fleischman School of Engineering at Tel Aviv University.
The TAU-SAT3 satellite, developed at the Fleischman Faculty of Engineering in Tel Aviv, is equipped with an optical device only a few centimeters long. This satellite is equipped with a battery manufactured by the Israeli company Epsilor, which will provide energy for the entire duration of the satellite’s operation in orbit.
Professor Eliaz said: “As the satellite passes over Israel, the device will emit light at different wavelengths and the ground station telescope will identify this microscopic light, lock on to it and track it.”
“However, when the optics are facing the ground station, the antenna points in a different direction.”
“As a result, a significant part of the data may be lost. The novelty of this project is the ability to reconstruct lost data in real time using intelligent signal processing algorithms, developed at Tel Aviv University from communication systems installed both in nanosatellites and on the ground. stations”Professor Eliaz explained.
The nanosatellite is part of a series of three satellites that Tel Aviv University launched into orbit in less than three years, participating in the global space revolution, opening research opportunities for civilian institutions and businesses.
