The Ct-G551 GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that
fully utilized SiRFstarV upgraded features. This 48-channel Global Positioning System (GPS)
and Global Navigation Satellite System (GLONASS) receiver is designed for a wide range of
OEM applications and is based on the GPS signal search capabilities of the SiRFstarV
CSRG05e ROM chipset, SiRF’ s newest chipset technology. The Ct-G551 provides flexible bus
interfaces (UART).
