The satellite earth station antenna system as a whole can be divided into four parts: antenna system, feed network system, antenna pedestal system, and antenna control system. The antenna feed network is the last link of the earth station satellite uplink antenna. In order to ensure the normal transmission of electromagnetic wave signals, the feed…
Typically, radio frequency devices(RF devices)include two types of active devices and passive devices. Active components are microwave components that require external power supply, such as PA, LNA and RFIC, etc. Passive components include passive filters, power dividers, and other microwave components that can work without external power supply. Whether it is an active device or…
With the rapid development of modern science and technology, people’s demand for information transmission is getting higher and higher. As we know that communication satellites with the characteristics of large coverage, long communication distance, short construction period, and its communication cost are independent of distance, which have an indispensable position and play an important strategic role in satellite…
As we all know, when the satellite earth station is newly built, expanded and updated, the network access verification test is required. According to the satellite network management convention given by the satellite company, we can see that the network access verification test mainly includes the following four parts for reference. This time we focus…
As we know that satellite communication system is kind of open system and the main usage is to transmit signal. It means that satellite communication system is easier to be interfered by some outside factors. Let us show you more details of causes and solutions about satellite communication interference. satellite communication system In general, common…
Antesky is a professional earth station antenna manufacturer, based on our experience between our customers, we found some customers’ testing methods are with some difference, so we’d like to share our earth station antenna testing method here for your reference. And we will introduce our testing method for earth station antenna including Radiation Pattern, Gain and…
As we know that antenna is transmitted signal via microwave, which is effected by environment conditions.Antenna efficiency will be deducted when antenna reflector is covered by snow. In the mean time, high noise temperature will disturb antenna receiving and transmitting.In order to assure antenna efficiency and to lower noise temperature, it is required to install…
It is important and necessary to do testing and debugging before antenna accessing to the network officially. Based on our experience, there will be some problems when doing test like no receiving signal, which is normal and allowable. Please do not be worry about that. We can solve it with ease per our expertise.…
Orbital inclination is the angle between the plane of an orbit and the equator. An orbital inclination of 0° is directly above the equator, 90° crosses right above the pole, and 180° orbits above the equator in the opposite direction of Earth’s spin. Orbital inclination measures the tilt of an object’s orbit around a celestial…
You need to know two major things right away: Design a VSAT transmitting network, first you need to know the information capacity and quality which need to transmit,each communication link from each information, firstly calculate the occupied bandwidth and occupied Satellite transmitting power. According to Satellite transmitting power and communication quality specification, through link budget…
