VSAT system uses geostationary satellite. A geostationary satellite is any satellite which is placed in a geostationary orbit. Satellites in geostationary orbit maintain a constant position relative to the surface of the earth. Geostationary satellites do this by orbiting the earth approximately 22,300 miles or 36,000 km above the equator. It will stay in that same spot above the earth. Its latitude stays at zero and its longitude remains constant.
What is the typical satellite life-span?
Geostationary satellites typically have a life span of between 10 to 15 years. At the end of its life-span, the satellite operator will normally lunch a new satellite as a replacement.
Where can we install a VSAT terminal?
VSAT terminal can be installed virtually anywhere, as long as electricity is available at the site. That what makes VSAT solution suitable for locations in-accessible by other modes of telecommunication system.
How long is the latency for VSAT connection?
Due the long distance between earth VSAT terminal and the satellite, it sure takes longer compare to cable or fiber. The latency, on in VSAT terms, RTT (Round Trip Time) for a VSAT network is around 600 ms. This is the time it takes, for the data to originate from Point A, goes to the satellite, come down to Point B, goes back up the satellite, and return down to Point A.
Which is the best VSAT solution between SpaceLink Broadband, Direct and Mesh?
The best is solution is what meets the customers’ requirement both technically and commercially. Each solution has its own unique advantages and disadvantages, with a different cost. In terms of cost, generally Spacelink Broadband is the lowest, Spacelink Mesh the more expensive solution and Spacelink Direct in between. However, this would also depends on the size and network configuration.
