Features:
- SiRF Star V ultra low power chipset
- GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy
- Compact module size for easy integration : 15 x 14 x 2.8 mm

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).
The Ct-G551 is designed to allow quick and easy integration into GPS-related applications such as:
-Mobile gaming
-Cellular handsets
-Cameras
-Asset tracking
-Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing
-Opportunistic ephemeris decode and advanced power management, which enable the GPS receiver to stay in a hot-start condition nearly continuously while consuming very little power
-Full support for client-based and server-based SiRFInstantFixTM
-Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance
-Use of software control modules to achieve power saving state
