The Leadtek GPS 9101 module (LR9101) is a
high sensitivity, high gain, low power and very compact
Surface Mount Device (SMD). This 20-channel global
positioning system (GPS) receiver is designed for a
broad spectrum of OEM applications and is based on the
fast and deep GPS signal search capabilities of
SiRFStarIII? architecture.
