3-axis stabilized antennas have to be used on maritime vessels for many years to compensate for the ships movement to track a satellite signal. There are 4 main antenna manufacturers that the majority of VSAT (and TVRO) satellite service providers …
Satellite communication is used for internet connection in remote areas of the world where a connection to the traditional copper or fibre network is not possible or used as a backup communication link for mission critical systems. VSAT is an …
When installing coax cable you need to know the distance of the run for the maximum coax cable lengths due to the attenuation of the L band RF signal and voltage drop on the coax cable between the outdoor equipment …
Prior to attempting to point the dish at the satellite you need to pre-set the polarization angle (also called skew) of the RF feed horn assembly. The NOC (Network Operations Center) should be able to tell you what polarization of …
When installing a VSAT satellite equipment you will need to know what polarization is used on the link and you will have to set up the RF feed assembly correctly. Cross-Pol (or XPOL) and Co-Pol are used for linear links. …
Satoms are now offering free online training courses for the Satellite & Communications industries. These courses will provide in-depth technical content, Health & Safety and practical information working in these sectors. The courses will give you the technical knowledge you need …
Ensuring that the coax connectors (F-Type N-Type or BNC etc.) are properly terminated is vitally important if you want reliable communications. Poorly terminated connectors will cost you money, time and reputation. This poorly terminated RG-6 coax was used in a …
Latency time of a satellite VSAT link is a crucial factor when choosing to use a satellite system, it can affect the performance of your network and some applications experience issues when the latency is too high, not to mention …
VSAT rain fade is the deterioration of the microwave RF signal levels caused by rain precipitation on either end of the satellite VSAT link. Typically, Ku and Ka band links are affected most (frequencies above 11GHz) and can occur at …
What is Adaptive Coding Modulation (ACM)? Adaptive Coding and Modulation (ACM) is a technology which automatically changes the Forward Error Correction (FEC) and modulation utilized on a satellite link to compensate for changes in link conditions, so that it is …
