Ct-G431 GPS模組

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

• Based on the high performance features of the SiRF Star IV low power single chipset.
• Built-in high gain amplifier and bandpass filter
• RoHS compliant (lead-free)
• Compact module size for easy integration: 15x14x2.8 mm (590.6x551.2x110.2 mil)
• SMT pads allow for fully automatic assembly processes equipment and reflow soldering

Performance

• Highest performance GPS PVT Engine.
• High acquisition sensitivity for fast TTFF
• Extremely low weak signal tracking sensitivity
• High jamming immunity
• Smallest footprint and total solution size
