How Does Mobile Satellite TV Work?

Mobile satellite TV has been around for years, but it is was only available to people who had busses, RV's or boats large enough to accommodate a large satellite dish. 
Nowadays, people can purchase mobile satellite dishes that are much smaller and can be mounted on the roof racks of cars, vans, or SUV's. 

Mobile TV via satellite works best when you can be out on the open road rather than in the city or somewhere that your reception can be scrambled or blocked by buildings or other obstructions.  Most mobile systems come with a rooftop antenna, a floor mounted receiver, and remote control.  Your in-car screens and connection service fees will cost extra. 

The mobile satellites contain antenna elements that draw signals in from the sky.  Mobile systems use GPS (Global Positioning System) to track their position and this
compensates for the constant moving of whatever vehicle you are traveling in.  This allows for a digital signal which provides a clear, constant picture even though your
vehicle is in motion.  This is much better than the flickering and shaky pictures once associated with mobile television antennas and receivers. 

Your satellite signal will remain strong and focused as long as your dish is pointed towards the south which is where the orbiting satellites are located.  You should make
sure that your mobile dish, like your home satellite dish, is free and clear of obstructions as this will cause a disrupted signal.  A big positive for mobile satellites is that they are less susceptible to being filled with debris and rain. 

For now, most satellite mobile TV is costly; approximately $2000 for the most basic models.  On the plus side, if you are already a satellite TV subscriber, you can usually get mobile service for quite a bit cheaper as a part or as an extension of your existing subscription.  The user feedback is very positive so far and it will probably only get better as the technology evolves.
