ST-Ericsson, Broadcom Launch GPS + GLONASS Receivers

摘要

Two receiver makers are introducing chips aimed at consumer devices to acquire both GPS and GLONASS satellite signals. Compared to GPS-only solutions, receiving signals from the additional 21 GLONASS satellites will dramatically improve positioning accuracy in dense urban canyons and increase time to first fix, manufacturers say. ST-Ericsson's new CG 1950 is a GPS/ GLONASS receiver built in 45 -nanometer silicon, enabling manufacturers to produce low-cost devices capable of supporting highly accurate navigation, mobile social networking, augmented reality, and other location-based services, the company said.The low-power CG 1950 is designed to be integrated into mobile phones, camcorders, cameras, and other mobile devices.
