Recently, Galaxy Aerospace successfully carried out the first domestic KA/Q/V -band low -orbit broadband test constellation "Little Spider Web" car "Little Spider's Caps" test. The test broke through the vehicle "Motion Zhongtong" antenna under actual vehicle driving conditions. The problem of accurately tracking the low -orbit and high -frequency satellites in real time has achieved a continuous satellite communication, and an important step in the exploration of the low -orbit satellite Internet application.

Popularly speaking, "Movement" means that the satellite terminal can communicate during mobile, and the terminal can be installed on a car, train, ship, aircraft and other carriers. The car "Movement" terminal requires that the antenna can quickly and accurately perceive the posture changes in the vehicle driving process. Through the beam control tracking algorithm, the extremely narrow beam formation of the antenna is accurate to accurately align the satellite in real time in the bumps of driving.

The car "Dynamic Zhongtong" test relies on the "Little Spider Web" of the 5G test network of Star Di. On March 5, 2022, Galaxy Aerospace successfully launched six low -orbit broadband communication satellites independently developed, forming my country's first low -orbit broadband communication test constellation to build a "small spider web".

It is understood that this car "Motion Zhongtong" test, the car is equipped with a flat -type phased array terminal, which realizes a stable low -orbit broadband network under high -speed driving, turning, up and downhill. -Fi connects the low -orbit satellite network with mobile phones and laptops, and experiences Internet services such as smooth browsing webs, video calls, etc., delayed low, and good network speed experience.

The flat -wave phase control array of the tablet using this test is jointly developed by Galaxy Aerospace and domestic partners. This phase -control array antenna terminal is designed with autonomous controllable radio frequency receiving chips. The advantages of contour, high gain and low cost.

With the continuous development of the phase control array antenna technology, the use of low -oriented "movement" will be more convenient. In the future, donkey friends who are on the desert off -road adventure, holidays on the cruise ship, and emergency vehicles to the front line of rescue and disaster relief need to be special. Users who connect to the network under the environment can quickly access the high -speed network through the "Movement". Galaxy Aerospace took the lead in carrying out the engineering exploration of the low -orbit "Dynamics". In the future, we will promote the "Dynamic" to more application scenarios such as ships and airborne, and lay the foundation for the promotion of the low -orbit satellite Internet. Help my country's satellite Internet construction.
