According to foreign media reports, US NASA's latest Swan ISS freight mission will be conducted on Monday on the local time, except for some experimental supplies and daily replenishment, there will be 3 cubesat, one of which is equipped with radar, this is the first one Cubesat satellite with radar.
It is understood that the three miniature satellites are probably only 26 pounds (11.8 kg), which will be used to display new technologies on the track.
Cubesat has made great progress since the first time the platform of the Thunder future space engineer has been introduced. Today, they are increasingly used to collect near-way track data, and even two are on the way to Mars. For this cube spacecraft of this 4x4x4 inch (10x10x10 cm), it only needs to operate the smartphone level.
Raincube
On May 21, 2018, three Cubesat shifted from the NASA's Wallops flight launch base, which will be deployed to the near-territory track after separation with unmanned space ships. One of them will be a satellite equipped with radar, referred to as Raincube. It is a type of satellite loaded with an active radar system. This satellite uses a stretchable antenna of about 20 inches (50 cm) and operates under high frequency Ka band. NASA, which enables data to grow in an exponential level in the data transfer of long distances.
NASA Earth Science Technology Office Earth Science Technology Space Verification Project is a demo experiment to monitor Earth weather like a larger traditional satellite but can achieve faster, lower cost, and more flexible purpose.
EVA PERAL EVA PERAL EVA PERAL, a Raincube, a procoction laboratory of Pasadina, California, pointed out that a group of RainCube observes the internal structure of the weather system.
Cuberrt
The second Cubesat is a radio frequency interference technology satellite for improving space data collection methods. NASA said that RF interference (RFI) is becoming a problem of space microwave radiation meter of land humidity, meteorology, climate, and other land phenomena.
In order to overcome the interference caused by the mobile phone, radio and television, Cuberrt will establish a prior art for processing RFI, which is capable of filtering out RFI damaged data by using a large amount of data. It is hoped that the new subsystem of Cuberrt can detect RFI in real time and filter out of RFI damaged data in real time on miniature spacecraft.
Tempest-D
The third satellite is the time experiment of the Tempest-D) task, which will demonstrate a new five-band radiation meter based on new low noise amplifier technology, which can be used to study cloud processing, storm development and determination. Start rain. By changing the position and height, Tempest-D may be able to achieve a goal, and more quickly to the traditional satellite, and traditional satellites can only re-access a storm system every three hours.
STEVEN Reising, Colorado State University, said: "With the same class Tempest Cubesat satellite group, we can take a look at how the storm is formed every 5 to 10 minutes."
