 Ct-G433 |
|
|
| |
 |
|
The Ct-G433 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 architecture, SiRF’s newest chipset technology.
The Ct-G433
provides flexible I/O interfaces (UART , I2C
and SPI which can be defined by customer).
Ct-G433 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
