Application of portable satellite communication flyaway antenna in emergency disaster relief

In emergency disaster relief, keeping communication smooth is an important condition to reduce disaster losses and reduce the impact of disasters, and satellite mobile communication is an effective means to ensure smooth communication. As an economical, practical and reliable emergency communication mode, portable flyaway antenna plays an important role in the application of satellite mobile communication in…

Instructions of Earth Station Antenna Feed Film Replacement

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…

RF devices in Satellite antenna communication(Passive devices)

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…

How do sun outage and eclipses affect communication satellites?

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…

How to access the network for satellite earth station?-Network access verification test for satellite earth station antenna

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…

Introduction and solutions about interference problems in satellite communication

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…

Comparison of several de-icing system devices for satellite antenna

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…
