88L1000 Product Brief

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.
KEY FEATURES AND BENEFITS
SPECIAL FEATURES
• Ultra small and low power single-chip GPS Receiver
BENEFITS
• Extremely small solution size of <25 mm2 for integrated solution
• <40 mW full power continuous tracking and <8 mW power-saving
mode maximize battery life
• Highly integrated Host Software Library
• Faster first-fix times with a client-server extended ephemeris solution
• A-GPS library with 3GPP SUPL and Control Plane support
• Seamless integration into Android, Windows, and Linux platforms
• Anti-jamming Technology
• Automatically scans, detects, and removes in-band tones
• Anti-jamming engine handles a maximum of 3 tones up to -80 dBm
• Accurate tone-frequency tracking detects tone disappearances
and tracks tone drifts as fast as 500 Hz/s
• Advanced Fusion Algorithms
• Wi-Fi and Cell-ID assistance for high availability coarse location
• 10 degrees-of-freedom MEMS sensors determine orientation
and position in the absence of satellite or other radio signals
• Intelligent, context-aware navigation performance and power optimization
