Sirf Technology Inc. has developed a low-cost Global-Positioning (satellite) System (GPS) chipset and modular operating software package aimed at consumer applications. Sirf hopes that the lower costs will prompt OEMs to build a wave of new products incorporating GPS. The company is already beginning to work with OEMs on products scheduled for Christmas 1996 introduction. For example, Mitec Inc. is building a low-cost, PCMCIA GPS add-in card for portable computers.
