Ct-G431 GPS module is a high sensitivity, low power, Surface Mount Device (SMD)) that fully utilized SiRFstarIV upgrade features. This 48-channel global positioning
system (GPS) receiver is designed for a wide range of OEM applications and is based on the GPS signal search capabilities of the SiRFstarIV GSD4e chipset, SiRF’s newest chipset
technology.
The Ct-G431 provides flexible I/O interfaces (UART is default, I2C and SPI by customer requirement).
The Ct-G431 is designed to allow quick and easy integration into GPS-related applications such as:
PDA, Pocket PC, Tablet and other computing devices
Fleet Management /Asset Tracking
AVL and Location-Based Services
Hand-Held Device for Personal Positioning and Navigation
Hardware and Software
