b1SATCOM-On-The-Move (SOTM) stands for Satellite Communication on the move, a mobile satellite technology, which is mostly used for military purposes. A vehicle mounted with SATCOM antenna can access satellite or space station even when it is moving. This is an important part of military warfare. There are a number of benefits of deploying this communication technology. Some of the key benefits of SOTM are: it guarantees the effectiveness of warfare, lethality, and survivability. These key benefits have made SOTM a fundamental defense communication system. Initially, it was only used by US military for defense purposes. Later on, it surfaced as a commercial commodity. Hence, commercial satellite industry emerged as a new sector. Figure 1 illustrates a mobile vehicle using satellite technology used in military agencies.

What are the applications of SATCOM on the Move Systems?

When a satellite revolves over the equator of the Earth, it can transmit signals to the extremes of both north and south of a longitude. In summary, when a satellite is hovering along any one longitude of the earth, the station on earth can receive data signals from any point on the ground.   Undoubtedly, with SOTM the defense technology has taken a leap.

What are the future challenges faced by the SOTM Technology?

b2However, there are some potential challenges faced by this technology. Challenges can be based on weight, size, Radio frequency, Protocols of the networking, data rate, and above all vehicle platform dynamics. On the basis of the technical specifications, there are different types of SOTM devices. Portability of the device is the most vital challenge faced by the manufacturers of the SATCOM-enabled products for vehicles. The lighter the device, more acceptability it will get.   Another challenge faced by SOTM is the outage of the radio frequency used for operating and connecting the device for a time period. Interruption can be caused due to bad weather conditions and lack of connectivity inside the tunnels. However, if SOTM device is powerful enough, it can resume operation once you are out of the obtrusion.

Telxperts provides intensive learning to SOTM systems, latest technologies and performance in this training course. This training course focuses on SATCOM services, SOTM fundamentals, techniques, Orbital and spectrum consideration for SOTM and Satellite Communication Evolution to Protected Satellite Communication.
