Over 40 mln Global Navigation Satellite Systems (GNSS) receivers were shipped in 2005, but in 2011 the market will have grown to nearly 300 mln shipments, according to ABI Research. That growth will not occur evenly across the board. In 2005, in-vehicle navigation systems accounted for just 26% of the total shipments, but 34% of worldwide GNSS hardware revenues. In 2011, in contrast, in-vehicle navigation shipments will represent just 16% of the total market, but will still deliver 29% of the hardware revenue. In 2005, communications accounted for 43% of the total market in terms of shipments. In 2011 that will have grown to 69%, but the revenue derived from it will have doubled, from just 9% in 2005.
