Mobile handset module

GPS World, Dec, 2004

Seiko Epson Corporation has developed the S4E 19863 single-chip GPS module with -160 dBm max sensitivity for use in next-generation mobile handsets equipped with built-in GPS support. The GPS module supports the three 3GPP-compliant positioning modes (MS-based, MS-assisted, and autonomous) and includes a GPS baseband processor, GPS RF receiver, and peripheral circuitry, though not a temperature-compensated crystal oscillator (TXCO). Reported positioning accuracy is less than 10 meters outdoors, less than 35 meters indoors. Interface operating voltage is 1.8 or 3V, and internal operating voltage is 1.5 or 1.8V. The chip measures 13 X 8 X 1.28 millimeters. Seiko Epson Corporation, Tokyo, Japan.
