Marvell 88L1000 GPS Hybrid Location Processor PRODUCT OVERVIEW The Marvell® 88L1000 GPS Hybrid Location Processor delivers the lowest-power location solution in the smallest size for embedded systems including smart phones, feature phones, notebooks, tablets, cameras, and other mobile devices. The 88L1000 provides accurate position data, both outdoors and indoors, useful for turn-by-turn navigation, location-based services and games, asset tracking, social networking, and geotagging. The 88L1000 provides both autonomous and assisted GPS modes and is fully 3GPP and E911 compliant. The 88L1000 is integrated with Wi-Fi and Cell-ID positioning technologies as well as MEMS sensors that deliver accurate location and motion sensing, even in the absence of GPS satellite signals. Environmentally aware and intelligent algorithms ensure that only the necessary technology components are activated to quickly and efficiently determine the device’s location, while using as little energy as possible.
