The Ct-G430 GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that can be compatible to
Ct-G348 or 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-G430 provides flexible I/O interfaces (UART is default, I2C and SPI by customer requirement).

The Ct-G430 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
  • All applications of battery drive device that needs lower power consumption
