Features:
- SiRF StarIV internal ROM-based ultra low power chipset
- Compact module size for easy integration: 22 x 18 x 7 mm
- Ct-G434 smart antenna module
- Operating at 1.8V signal level

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). 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
- Use of software control modules to achieve power saving state

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


Interface
- Multiple host interfaces (UART)
- 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 -160dBm, 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
