Satellite tournament
A satellite tournament is either a minor tournament or event on a competitive sporting tour or one of a group of such tournaments that form a series played in the same country or region.
Poker
A satellite tournament in poker is a qualifying event. Winners of these satellites usually win the buy-in fee to a larger, more prestigious tournament like the World Series of Poker Main Event. Although there are some land-based satellite tournaments (usually for very high-stakes tournaments), most of them are online-based. Some sites, like PokerStars, maintain several tiers of satellites. A player can thus start out at one tier (not necessarily the lowest one) and play his way to a higher tier. The entry fee for each tier is always higher than the fee for the tier below it, with the first tier being the cheapest.
Tennis
In professional tennis, satellite tournaments were four-week tournaments, typically organised by a country's national tennis association and overseen by the International Tennis Federation. They were played by players who were ranked outside the top few hundred by the Association of Tennis Professionals, with openings for unranked players in the qualifying draw. Total prize money ranged from $25,000 to $50,000 for the tournament. Players successful at this level of pro tennis would move on to play ATP Challenger Series or even top-flight ATP Tour events. The men's satellite tournaments were discontinued following the 2006 season as the circuit moved exclusively to one-week Futures tournaments.
