At the 6th Science and Technology Fair, which was opened yesterday, the “Low-Guard” laser pointer interception system developed and produced by China Jiuyuan High-tech Equipment Co., Ltd. attracted everyone to watch.
With the increasing number of drone players, the "black fly" interference with civil aviation has been repeatedly banned, and traditional air defense methods are difficult to combat such "low and small" aircraft. The "low-altitude guard" is a low-altitude security system developed to solve the "low-slow" threat.
According to reports, the "low-altitude guardian" system integrates command and control, radar search, photoelectric warning, and laser strike. It can achieve target search, capture, lock tracking and shooting down within a radius of 1-3 kilometers. The collateral damage, flexible application, and low cost of single-use are effective means of disposing of "low-slow" aircraft.
At present, China Jiuyuan High-tech Equipment Co., Ltd. has laid out the production of “low-altitude guards” in the Mianyang Economic Development Zone.
ESA Aeolus satellite has begun its mission to monitor the global winds with lasers
On August 22nd, the European "Aeolus" (the guardian of the wind in Greek mythology) satellite was successfully launched from the European spaceport base in Guyana, France, on a Vega rocket, and executed in the high altitude of 320 km (200 miles) from the Earth. A three-month mission. It is reported that it has begun to emit ultraviolet pulses from the laser to monitor the wind on the earth.
Aeolus is the fifth Earth exploration mission planned by the European Space Agency. This new mission is also the 50th launch of Ariane Space for the European Space Agency.
It is reported that Aeolus is equipped with a single instrument: Doppler wind laser system: an advanced laser system designed to accurately measure global wind patterns from space. Its laser emits 50 strong UV pulses per second into the atmosphere and measures the signals of molecules, dust particles and water droplets in the air to create a wind speed profile at a minimum of 30 kilometers (19 miles) from the atmosphere.
Ariane Space said the mission will provide much-needed data to improve the quality of weather forecasts and contribute to long-term climate research.
Josef Aschbacher, director of the Earth Observations Program at the European Space Agency, said: "This new technology fills a huge gap in our meteorology data, allowing us to monitor global wind movements in a cloud-free atmosphere."
