Ct-G431 GPS模組

Ahighsensitivity,lowpower,SurfaceMountDevice(SMD)

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 Highest level of BOM integration Value added software enhancements Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted) – Need operator support Embedded CGEE / SGEE (Need server support) SiRFGeoRecovTM Reverse EE Cold/Warm/Hot Start Time: 35/35/1 sec. at open sky and stationary environments Reacquisition Time: 0.1 second RF Metal Shield for best performance in noisy environments

	Interface TTL level serial port for GPS communications interface Protocol: NMEA-0183/SiRF Binary (default NMEA) Baud Rate: 4800 bps
