Today one of our engineer do the maintenance of our 7.3m ku-band antenna for one of our users. When he arrived at the antenna site, he found a bird’s-nest on our antenna, the birds make the sub-reflector as their home, which is very interesting. At this time, our engineer met a question: Should we destry this bird’s home…
Largest satellite dish Overview of FAST（Five-hundred-meter Aperture Spherical radio Telescope 500M） In the year of 2006 and 2012, Antesky participate in the project of 50m 50m Radio Telescope (VHF/UHF-, L-, S/X-, Ku-band)&65m Radio Telescope Antenna(L/S/C/X/Ku/K/Ka/Q band), and we Antesky do the components production, installation,debug and testing.the Chinese government is now establishing the biggest single…
Satellites, gravity and circular motion Since entering space age, human beings has launched more than 4000 spacecrafts into the space. At present, there are about one thousand artificial objects in geostationary orbit, 5% of which is working, while the left 95% of which will become space debris without working. Until now, there are nearly 300…
1. General Flyaway antenna is of offset antenna, which is comprised of reflector, feed system, azimuth adjusting mechanism, pitch adjusting mechanism and triangular pedestal. The antenna is packed in a backpack which can be loaded in automobile like jeep. 2. Structural Characteristic (1) Flyaway Antenna Structure Characteristic In order to embody…
The characteristics of antenna system performance are as follows: 1.The antenna is shaped and assembled by four pieces of aluminum panels, with characteristics of large rigidity, light weight, high precision of profile, and convenient assembly. 2.The antenna is packed in a case, which is convenient to carry, suitable for long highway transportation and taken by…
Description Today’s requirements for secure, interoperable communications systems, as well as rapidly deployable networks for emergency response, are driving the need for inexpensive, simple, satellite earth station antennas, ranging in size from sub-meter to 5 meters in diameter. When selecting and siting antennas, systems engineers rarely consider the earth station antenna’s vulnerability to damage or…
I Brief Introduction Satellite communication earth station antenna is one important aspect of antenna field. With the continuous development of satellite communication, technology of antenna used in satellite communication earth station has developed rapidly. Firstly, it is development of antenna frequency. It develops from C-band to Ku-band. And it also opens satellite communication business at…
1. Introduction Building a video news gathering system which is comprehensive, three-dimensional and multi-echelon has been put on the construction schedule. The system can expand business in a maximum limit and improve real-time transmission capacity of audio and video business, secure a leading position in news gathering technology field. The construction goal of complete system…
I. Antesky Antenna tracking system components and working principle 1. Antenna tracking system composition Antenna automatic tracking system is mainly composed of indoor antenna control unit (ACU) and outdoor antenna drive unit (ADU).The control command are operated through the programmable terminal display to realized the antenna azimuth, elevation and polarization angle adjustment. (1) Antenna Control…
VSAT Antennas become more and more popular in recent years, however, some people don’t know how to select the VSAT antenna site, and this article will give you guidance. The VSAT (Very Small Aperture Terminal) is a telecommunication system based on wireless satellite network. Although it is easily implemented due to the wireless nature of…
