Ct-G434 smart antenna module |
|
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
Features
Performance
High Performance Solution:
- High sensitivity navigation engine (PVT) tracks as low as -160dBm
- 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) – With operator support
*2 Embedded CGEE / SGEE (With back-end 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.
RF Metal Shield for best performance in noisy environments
( *2, Above features should be combined with external EEPROM, please refer to application note. )
Interface
Multiple host interfaces (UART, I2C, and SPI)
Secondary I2C port for MEMS connection
Protocol: NMEA-0183 (default)
Advantages
Built-in LNA.
Built-in internal ROM and based on Firmware 4.x.x
*3 Embed CGEE (Client Generated Extended Ephemeris) that can capture ephemeris data from satellites locally and predicts ephemeris out to 3 days. So if the module was off within 3 days, it could complete positioning process with limited time just like hot start.
It can remove in-band jammer up to 80db-Hz and track up to 8CW jammers, so the module can prevent GPS signal interference when design-in the electrical device with noisy electrical signal interferences such as Laptop, mobile phone, DSC, etc.
Tracking sensitivity as low as -163dBm, even without network assistance.
Support SiRF Aware technology
Support adaptive “Micro Power Controller” power management mode
*4 Support MEMS sensor through I2C interface. (V4.X.X firmware is available for now)
MEMS interrupt can improve Micro Power Mode performance.
Only 8mW Trickle Power, so user can leave power on all day instead of power off
Suitable for battery drive devices that need lower power consumption application
Cost saving through elimination of RF and board to board digital connectors
Flexible and cost effective hardware design for different application needs
( *3/*4, Above features should be combined with external EEPROM, please refer to application note. )
