According to the production progress of 4.5m C/Ku 4 port Motorized Antenna, Antesky did the testing before delivering product to customer. In last week, Antesky engineers finished the 4.5m antenna testing based on the following parameters: Antenna gain, Efficiency, Radiation pattern, Noise temperture, Isolation and Tracking accuracy etc. After careful testing, all the technical specification can…
Elon Musk once said,” If rocket can be resued as airplane, the cost to enter into space will become 100 times lower.” At 9:00A.M. of Dec 22nd,2015, SpaceX launched the Falcon 9 rocket researched and developed by themselves into Space from Florida Kennedy Space Center. This is the first time for civilian companies to send effective payload to…
Satellites at different earth orbits present various perspectives for many reasons. Usually there are three kinds of orbits in essence, which are high Earth orbit, medium Earth orbit and low Earth orbit. High Earth Orbit It is also called geosynchronous because the satellite seems motionless to the earth at the same turing speed as the earth. These…
Aluminum mesh antenna,When talking about antennas, what will appear in your brain? A paraboloid, a big and high object, white color etc.Actually there are a variety of antennas around us. They divided into variable categories according to different operations, applications, structures, wave length, etc.Today I’d like to know some antennas with you. Look at the following…
1. What is Rain attenuation？ During the operation of the satellite, if it encounters a rainy area, the radio waves emitted by the satellite will not only be partially absorbed by the rain, but the rain will also scatter the radio waves to a certain extent. Under the joint intervention of the two effects, the…
This is a list of satellites in geosynchronous orbit. These satellites are commonly used for communication purposes, such as radio and television networks, backhaul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do. A number ofweather satellites are also present in geosynchronous orbits. Not included in the list below are several more classified military geosynchronous satellites, such as PAN. Listings…
ESA is adding a new 4.5m “acquisition aid” to its current New Norcia, Western Australia, tracking station. It has been ready to catch the first signals from new launched missions. This new antenna can acquire and track during new missions’ critical initial orbits, whose range can be up to about 100 000 km. It can also control a…
