Epson announced the development of its cutting-edge Infineon XPOSYS chip, scheduled for mass production by the end of 2009. The new chip is an “Assisted GPS” device, measures 2.8mm x 2.9mm, and will be 25% smaller than any A-GPS chip on the market. Furthermore, the XPOSYS should use only half the power of current-generation chips. Epson promises a greater sensitivity in indoor environments.
A-GPS is used extensively with GPS-capable cellular phones and enhances the start-up performance of GPS-based systems. This technology standard will likely be the future of GPS development for the next several years.
