Extended Abstract—
On the move, satellite communication is a major new capability that is being sought by the military to support
operational concepts. Because of their size and weight, small aperture terminals are very attractive in such
communication on the move applications. It can also serve civilian purposes like in civilian transportation water
vessels and road transports can use a suitable and efficient version of it.[1] Establishing satellite communication
with a moving platform efficiently is our research area.
Our main objective of this research is to make on the move satellite communication more efficient and available
to all military vehicles for safe communication in the war-zone and remote areas. It should also be available for
civilians to broadcast TV channels live on their moving transportation system.
In this research, we are using mixed methods of research. We are doing the archival study, experiments,
resources, and data analysis. But most of this research part is experimental and this keeps the highest part of
the research.
On the move satellite is not a new concept. But its
operational cost is very high and not available for
civilian use. In civilian cases, the concept of DTH (Direct
to Home) is widely now used. This system establishes a
line-of-sight communication with a geostationary
satellite and maintains the line-of-sight in a fixed
position. On the move, communication face challenges
to maintain the line-of-sight.[2] In our research, we want
to develop a system that can maintain the line of sight
by using several sensors and other methods. According
to our analysis, available on-the-move systems use
various complex methods, their operation is terrain
dependent and their price is very high. We can provide
this for both military and civilian uses. We can mount this system above public transport like buses, launches,
etc. to entertain people by showing live television. We can use this system in disaster management by sharing
real-time situations and also the military mobilization and communication in remote unknown terrain.
There are so many challenges in this research. Maintaining the line of sight is not easy in the parking position.
There are a lot of scenarios created on the move like speed variation, slope variation, acceleration, brake, turn
rate, etc. We also have to consider the antenna errors, receiver errors, transmitter errors, etc. There are also some
issues with the power supply to the antenna and other sensors.[3]
We are at the very primary stage of this research. As we proceed forward, we will resolve all the challenges and
be able to build a stable platform for on the move satellite communication.
