 Ct-G432 |
|
|
| |
 |
|
The Ct-G432 is a high sensitivity, low power ,Surface Mount Device (SMD), that fully utilized SiRF star IV upgraded features. This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications
then based on the GPS signal search capabilities of SiRF
star IV GSD4e ROM chipset, SiRF’s newest chipset
technology.
The Ct-G432 provides flexible bus interface (Optional :
UART , I2C or SPI ).
Ct-G432 is designed to allow quick and easy integration
into GPS-related applications such as:
- Mobile gaming
- Cellular handsets
- Cameras
- Asset Tracking
- Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing.
- *2 Full support for client-based and server-based SiRFInstantFixTM
- *3 Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance
(*2/*3, Above features should be combined with external EEPROM, please refer to application note.) |

Performance
- High Performance Solution:
- High sensitivity navigation engine (PVT) tracks as low as -163dBm
- 48 track verification channels
- SBAS (WAAS or EGNOS)
- Active Jammer Remover:
- Removes in-band jammers up to 80 dB-Hz
- Tracks up to 8 CW jammers
- Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted) – Need operator support
- *4 Embedded CGEE / SGEE (Need b server support) speed up TTFF a lot and makes cold start time to be around 20 seconds
- SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode.
- Reacquisition Time : 0.1 second
- RF Metal Shield for best performance in noisy environments
( *4, Above features should be combined with external EEPROM, please refer to application
note. )
