 |
|
The Ct-G434 is a high sensitivity, low power and very compact smart antenna module,
with built in GPS receiver. This 48-channel global positioning system (GPS) receiver is designed
for a wide range of OEM applications then based
on the fast and deep GPS signal search
capabilities of SiRFstarIV GSD4e ROM chipset, SiRF’s newest chipset technology.
The Ct-G434
provides flexible I/O interfaces (UART , I2C
and SPI which can be defined by customer).
Ct-G434 is designed to allow quick and easy integration
into GPS-related applications such as:
- PDA, MID, and other portable devices
- Car and Marine Navigation
- Fleet Management / Asset Tracking
- AVL and Location-Based Services
- Hand-Held Device for Personal Positioning and Navigation
