美國政府規定，今年10月以後，美國市場上銷售的行動電話都必須具備衛星定位功能，以方便救援?

一般稱為E911法案. (原因就是來是911事件)
E911(Enhanced 911) 來源應該是緊急電話號碼911 (剛好911 事件在9/11 發生)
FCC官方網站
The wireless E911 program is divided into two parts - Phase I and Phase II. Phase I requires carriers, upon appropriate request by a local Public Safety Answering Point (PSAP), to report the telephone number of a wireless 911 caller and the location of the antenna that received the call. Phase II requires wireless carriers to provide far more precise location information, within 50 to 300 meters in most cases.
