Hammerhead^TM II
PMB 2525
Product Brief
The Industry’s Highest Performance GPS Receiver in the smallest package yet.
H a m m e r h e a d I I delivers all the performance of its predecessor, while
achieving a new benchmark for high performance Positioning & Navigation integration
into mobile devices.
U s in g c hip scale packaging (CSP) technology, its size (3.59 x 3.75 mm²) now
offers possibilities of integration into the miniaturizing world of mobile handhelds.
H a m m e r h e a d I I integrates a high performance A-GPS baseband processor
and a low-noise GPS RF front end. It comes packed with new software features such
as advanced multi-path mitigation that avoid large errors in urban environments
caused by reflected signal-in buildings and other structures.
Key Features and Benefits
■ Single-chip minimizing board space (< 50 mm² PCB area for complete A-GPS solution)
■ Advanced low-power 0.13 µ RFCMOS technology with smart power management
■ Real-time hardware correlator engine (fast acquisition and high sensitivity)
■ High sensitivity, -160 dBm, enabling indoor and deep urban operation
■ Built-in voltage regulators supporting single-power supply source
■ Multiple-mode operation
– MS-based (calculation of position in mobile handset)
– MS-assisted (calculation of position in base station)
– Autonomous (no assistance by network)
– Enhanced autonomous (using four day assistance data)
■ Multiple protocol operation
– Control plane (RRLP & RRC)
– User plane (SUPL)
■ A-GPS control software enables non disrupting call flow and ease integration
■ Standard compliant (exceeds requirements for 2.5 G and 3 G networks)
Note: The Hammerhead trade mark is owned by Global Locate, Inc
