Abstract

Модуль (программный или ASI) для использования в Центре Определения Положений Мобильных устройств (SMLC) или в мобильной станции, которая имеет приемник GPS (или приемник A-GPS) для определения ITOW для сигнала CNAV-1. Также предложено мобильное устройство с приемником GPS (или A-GPS), чтобы это мобильное устройство могло использовать ITOW (ITOW от CNAV-2 или вычисленный для CNAV-1) для однозначной идентификации эфемеридной информации в сообщении с требованием поддержки. Кроме того, предложен модуль для SMLC, через который SMLC сможет использовать поля IOD в сообщениях со вспомогательными данными для однозначной идентификации соответствующей эфемеридной информации.
